Anatoli Bugorski and the Splitting Headache. (Hit in the Face with a Particle Accelerator)

<p dir="ltr">Episode 9: Anatoli Bugorski. Anatoli and the Splitting Headache. </p> <p dir="ltr">One more story to tell today in our mini series of scientific heroes who work in dangerous mediums and, like the last couple of episodes, today’s story  is also a cautionary tale of sorts, but it’s a story of a mistake most of us won’t even have a chance to duplicate even if we wanted to. I’m looking forward to telling you about today’s subject, Anatoli Bugorski, but even MORE looking forward to the next few episodes when we dive into the primary sources - pre all of this societal polarization and vitriol - and learn in their own words what a Nazi is and what a Fascist is. What did each of those parties believe, what were their planks, and how did they behave? In a world where everybody who disagrees with you politically is a vile Nazi or Fascist, it might just be helpful to look up what each party was all about. That’s history-history, and a time period that is right in my wheelhouse, a few years before and after WW2.</p> <p dir="ltr">Sometimes science brushes so close to the edge that it leaves a scorch mark. Today’s story is about a man, unlike our other heroes of science, who escaped the flash “brighter than a thousand suns” ( Discover), even though it hit him square in the head.  It’s also about how a human life can thread the needle between disaster and miracle and keep on going, to finish a PhD, show up to work, and survive.</p> <p dir="ltr">This is the tale of Anatoli Petrovich Bugorski, “a Russian retired particle physicist … known for having survived a radiation accident in 1978, when a high-energy proton beam from a particle accelerator passed through his head.” Yep, you heard me correctly. Essentially, he is the Phineas Gage of the nuclear era. And if you don’t know about Gage…look him up. Ouch! </p> <p dir="ltr">We start in Protvino, in the Russian SFSR, at the Institute for High Energy Physics. Bugorski “worked with the largest particle accelerator in the Soviet Union, the U-70 synchrotron” (..). On July 13, 1978, he walked into the kind of malfunction that turns a routine check into legend: “he was checking a malfunctioning piece of equipment when the safety mechanisms failed. Bugorski was leaning over the equipment when he stuck his head in the path of the 76 Giga electron volt proton beam” (..).</p> <p dir="ltr">He didn’t really feel pain as such, at least not immediately. Instead, he saw light. Specifically, he “reportedly saw a flash ‘brighter than a thousand suns’” In that instant the beam “passed through the back of his head, the occipital and temporal lobes of his brain, the left middle ear, and out through the left-hand side of his nose”  The dose in the exposed pathway: “200,000 to 300,000 roentgens  Discover puts the energy another way: “2,000 grays … on the way in, and … 3,000 grays by the time it left. A dose of around 5 gray can be lethal to humans” (Discover). How do those two things cohere, considering that Bugorski didn’t die? I’ve no idea. Like Homer Simpson, I’m no nuclear scientist, and unlike Homor Simpson, I don’t even work at a nuclear power plant. </p> <p dir="ltr">Somehow, someway, Bugorski “understood the severity of what had happened, but continued working on the malfunctioning equipment, and initially opted not to tell anyone” (..). That detail feels very Soviet, very scientist, and very human: finish the job, then process the catastrophe. It reminds me of the time I was bit by a racoon…..And, you know what? Don’t expect anybody to make a podcast in the future about my raccoon incident…Bugorski’s story is a billion times better. </p> <h2 dir="ltr">Let’s talk about What Particle Beams Do (And Don’t Do) to Flesh</h2> <p dir="ltr">There’s a reason we generally don’t put our hands in beams. When I was a kid, if I heard my mom say that once, I heard her say it a million times. </p> <p dir="ltr"> As The Atlantic frames the broader thought experiment: “What would happen if you stuck your body inside a particle accelerator? The scenario seems like the start of a bad Marvel comic” (The Atlantic), according to the Atlantic, but a GOOD Marvel comic if you’re asking me. </p> <p dir="ltr">Accelerators “allow physicists to study subatomic particles by speeding them up in powerful magnetic fields and then tracing the interactions that result from collisions” (The Atlantic). But that neat chalkboard world becomes very real when “a beam of subatomic particles traveling at nearly the speed of light meets the flesh of the human body” (The Atlantic).</p> <p dir="ltr">Discover says it plainly: “protons are still very much physical objects, and when you take trillions of them and force them through something as delicate and complex as a human cell, the collisions tend to tear biological structures apart” (Discover). Radiation harms by “breaking apart chemical bonds that hold DNA and other cellular components together” (Discover). With enough energy, “cells are unable to duplicate and begin to die, leading to organ failure” (Discover). And yet, unlike fallout or whole-body exposure, “the particle beam was narrowly focused,” meaning “only his brain received any exposure to the radiation, keeping the damage concentrated to a single area” (Discover). That narrowness, Discover suggests, may be part of why he lived: “He may have just been lucky, and the beam missed important areas of his brain, or perhaps proton beams affect the body differently than other sorts of radiation” (Discover). Reading the Discover article, I wonder if they realize just how important the brain is. I don’t feel like Bugorski got lucky because the particle accelerator beam only hit him in the face. </p> <p><strong> </strong></p> <p dir="ltr">The Atlantic zooms out: this kind of radiation—protons at these energies—“is a rare beast indeed”  Almost no one ever encounters a dose like this in such a focused line. When they do, it’s usually deliberate and medical: “Particle accelerators can deliver targeted doses of radiation to cancer patients, a process known as proton beam therapy … Those doses are around 300 times smaller than the one Bugorski sustained” (Discover). So cancer-destroying proton beams are 300 times smaller than the beam that smacked our guy in the head. Wild! </p> <p dir="ltr">So no, this isn’t an origin story for Super-Anatoli. As the Discover article cracks: “Were this a comic book, Bugorski would certainly be endowed with fearsome powers … As it is, he’s probably just happy to be alive”  One possibility they didn’t consider is that Burgorski did, in fact, develop superpowers, but like Superman with his glasses on, he is clever enough not to advertise his powers to the rest of the world. Yeah, that’s the ticket. <br /> <br /></p> <p dir="ltr">Back to 1978. Like with Slotin, Kelley, and Daghlian, Bugorski’s Doctors expected a death watch. “They expected him to die, but he survived with severe but non-fatal injuries” (..). The physical toll was immediate and visual: “The left half of Bugorski’s face swelled up beyond recognition and, over the next several days, the skin started to peel, revealing the path that the proton beam had burned through parts of his face, his bone, and the brain tissue underneath” (..). Discover’s article version is also a tad grisly but concise: “his skin blistered and peeled off where the beam had struck” (Discover).</p> <p dir="ltr">Permanent damage for Bugorski coincided with the beam’s route through his head. He “completely lost hearing in the left ear, replaced by a form of tinnitus” (..). “The left half of his face became paralyzed due to the destruction of nerves” (..). “He was able to function well, except for occasional complex partial seizures and rare tonic-clonic seizures.” Or as Discover translates the neurology: “in the long-term, Bugorski suffered for a time from both petit mal and grand mal seizures and found that he became more easily mentally fatigued” (Discover). One other side effect: Apparently, The paralyzed side of his face never aged, but if you are dealing with wrinkles and looking for a fountain of youth style medical cure here, you might want to verify that in person before sticking your body into a particle accelerator.  </p> <p dir="ltr">What about his mind? Did he lose his wits? Most reports note that “There was virtually no damage to his intellectual capacity, but the fatigue of mental work increased markedly” (..). After the accident, Discover magazine reports that Bugorski “nevertheless went on to earn his doctorate, and even returned to work at the same facility where his accident occurred” (Discover). The Atlantic underscores the same improbable normalcy: “Despite having nothing less than a particle accelerator beam pass through his brain, Bugorski’s intellect remained intact, and he successfully completed his doctorate after the accident” That’s pretty impressive, and puts him in a tier of one. I’m pretty sure he’s the only guy in history to earn a doctoral degree after taking a million-mile fastball from a particle accelerator to the face. Impressive. </p> <p dir="ltr">After the accident, he “continued to work as a physicist … eventually becoming the experiment coordinator for the same particle accelerator by which he was injured” (..). In an institutional world that can sometimes be quick to sideline, that’s a quiet triumph.</p> <p><strong> </strong></p> <p dir="ltr">The human story here runs on two tracks: private medical vigilance and public silence. .. again: “Because of the Soviet Union’s policy of maintaining secrecy on nuclear power-related issues, Bugorski did not speak publicly about the accident for over a decade” (..). Meanwhile, he “continued going to the Moscow radiation clinic twice a year for examinations and to meet with other nuclear accident victims” (..). In that circle, he was “described as ‘a poster boy for Soviet and Russian radiation medicine’” (..).</p> <p dir="ltr">Money and medication brought their own hard edges. “In 1996, Bugorski applied unsuccessfully for disability status to receive free epilepsy medication” (..). It’s not just the US that denies legit insurance claims, folks. </p> <p dir="ltr">He “showed interest in making himself available for study to Western researchers but could not afford to leave Protvino” (..). There’s sadness tucked between those lines: a unique case that could teach the world, a scientist willing to help, and a visa-sized wall of costs and borders, red tape and bureaucracy. Ugh. </p> <p dir="ltr">Through it all, life continued. “Bugorski got married to Vera Nikolaevna, and they have a son named Peter” (..). Sometimes the most radical sentence, after 2,000 grays of piercing radiation in and 3,000 grays out, that’s pretty remarkable. </p> <p dir="ltr">Particle accelerators are weird and hard to understand for laymen like most of us. The Atlantic reminds us that particle physics often lives far from intuitive analogies. Compared to pictures from Mars, “CERN’s research doesn’t produce stunning, tangible images. Instead, the study of particle physics is best described by chalkboard equations and squiggly lines called Feynman diagrams” (The Atlantic). That distance from common experience is why even “some professional physicists” hesitate when asked what happens if you put a body part in a beam; in one interview, “Professor Michael Merrifield put it succinctly: ‘That’s a good question. I don’t know is the answer. Probably be very bad for you’” (The Atlantic).</p> <p> </p> <p dir="ltr">Now, about the numbers. The U-70’s beam energy was “76 billion electron volts,” and The Atlantic speculates Bugorski “might have experienced the full wrath of a beam with more than 300 times” the energy typically used in therapeutic settings (The Atlantic). That’s beyond catastrophic, if it’s delivered broadly. But, as Discover stresses, “only his brain received any exposure,” sparing “organ system[s]” that usually fail in radiation sickness </p> <p dir="ltr">And that flash? The Atlantic ties it to astronaut lore: “Apollo astronauts … exposed to cosmic rays containing protons … reported flashes of visual light, a harbinger of what would welcome Bugorski” (The Atlantic). Bugorski’s own report—“brighter than a thousand suns”—is both poetry and neurology. </p> <p dir="ltr">You know how they say that statistics lie? Here is a statistic that is a bit of a paradox in that it is both 100 percent true and a 100 percent misleading. Based on empirical evidence, the chances of dying from a direct hit in the face by a particle accelerator beam is 0 percent. </p> <p dir="ltr">Put another way, in the statistics of the world, 0 percent of the people hit by a particle accelerator beam in the head have died.<br /> <br /> It is, on paper, one of the single safest incidents known to man. Walking out to your mailbox, blowing your nose, swivelling in your chair, adjusting your airpods, and bending over to pet a friendly animal ALL have a higher likelihood of killing you - based on available statistics - then does a full on head shot from a fully operational particle accelerator, because Bugorski, as near as I can tell, is the only human in history to experience that, and he is still alive. It could be argued, in fact, that being hit in the face with a particle accelerator makes you absolutely immortal, but we should probably continue our observations a little longer before we break that news to the rest of the world. </p> <p dir="ltr">When we tell stories about scientific accidents, we often end with a policy, a protocol, a new rule on a laminated card. In this case, much of what survives is a man—and some unanswered questions.</p> <p dir="ltr">According to Discover: “what prevented him from experiencing much more damage is still unknown” (Discover). The focus of the beam “likely helped,” but perhaps “proton beams affect the body differently than other sorts of radiation” (Discover). The Atlantic adds that accidents like this are so rare that “the effects of super-high energy proton beams on the body are relatively unknown” (The Atlantic). That’s science’s honest shrug: sample size of one, no control group, ethics that forbid replication. As V.S. Ramachandran, the Indian-American neuroscientist, says,  “it takes only one talking pig to prove that pigs can talk” (The Atlantic). Bugorski is the talking pig of particle-beam human exposure—a phrase he surely never asked for, but one that marks a singular place in the medical literature of the unimaginable. By the way, I like the way Ramachandran’s mind works. </p> <p dir="ltr">One thing this episode and its predecessor have taught me is that radiation and dangerous chemicals rarely, if ever, lead to superheroes, and that is one of the great disappointments of my life. In my spare time, I like to treasure hunt with my metal detector, and have found all sorts of treasures and old coins, but no magic rings.<br /> <br /></p> <p dir="ltr">After the accident, Bugorski lived under secrecy, under observation, under the ceiling of a clinic he visited “twice a year” (..). He tried for disability medication help and was denied, but He kept working. He finished the doctorate. He coordinated the accelerator (..). He has a wife, and a family. He is, depending on what line you read last, either an emblem—“a poster boy for Soviet and Russian radiation medicine” or a private citizen who did the impossible thing and went home for dinner. He is still alive today and in his 80s. My deficit in the speaking and reading of Russian is a barrier to finding out much about his current life, as English speaking sources lack very few contemporary details on the life of Bugorski. </p> <p dir="ltr">What can we learn from Anatoli Bugorski? Just this: When life hits you full in the face with a focused beam from a giant particle accelerator, don’t quit, don’t give up, don’t stop…earn your doctoral degree and keep moving forward. And maybe get married and have a kid named Peter. Something like that. </p> <p dir="ltr">Our next set of episodes are all about what it actually means to be a Nazi or Fascist using primary sources from the 1930s-1960s…before all of today’s inflammatory rhetoric. I can’t go a day right now without reading a progressive on social media call a conservative a Nazi or Fascist or vice versa, and I hope it is time for all of us to learn precisely what those words mean, so that they don’t just become a synonym for something/somebody I don’t like. Until then - Keep Digging! </p> <h2 dir="ltr">Quoted Sources (as cited inline)</h2> <ul> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">Discover Magazine — “If You Stuck Your Head in a Particle Accelerator …” (Nathaniel Scharping, 2017): (Discover)<br /> <br /></p> </li> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">The Atlantic (Aeon) — “What Happens If You Stick Your Head in a Particle Accelerator?” (Joel Frohlich/Aeon):.

Quicksilver: The Life and Loss of Karen Wetterhahn

<h1 dir="ltr">Quicksilver: The Life and Loss of Karen Wetterhahn</h1> <p dir="ltr"> </p> <p dir="ltr">Hello friends, and welcome to episode #8. Today we have another riveting but tragic story for you.   </p> <p dir="ltr">If you haven’t listened to episode 7 yet, it isn’t absolutely necessary, but it would do you well to hear the stories of early nuclear pioneers like Louis Sloten, Cecil Kelly, and Harry Daghlian, and the dangers that ended their lives. I think this is going to be an intriguing episode, with a fascinating scientist that most won’t be familiar with.  </p> <p dir="ltr">Today is not so much in my wheelhouse - Nuclear history, toxic chemical history, safety history, and high velocity subatomic history. I’m not a scientist, and I didn’t stay recently at a Holiday Inn, but I am certainly a science hobbyist, and keep up with science news daily, and the fact that the last few topics are out of my milieu, so to speak, means I’ve had to research them more thoroughly, fact-check my assumptions, look up terms, and generally do the due-dilligance to get things right. I may miss something here or there, but I am trying hard to get it right. Just let me know where I whiff, and I can tell the DJ to fix it in the mix. </p> <p dir="ltr">You know the podcast things. Sharing the show, telling people about it, posting about it, and leaving Apple Podcast reviews all help…a lot. I appreciate those of you who do that. Thank you!<br /> Some stories make you hold your breath. Some make you check your gloves. Today we’ll do both, and hopefully, when we do - we’ll be all the better for it. </p> <p dir="ltr">We begin with the story of Dr. Karen Elizabeth Wetterhahn, chemist, teacher, builder of programs, and teacher of  people, and of one “tiny glistening drop” that rewrote laboratory safety across the world . It’s a story I want to tell with reverence and a little warmth, because we are talking about a person who balanced world-class science with backyard pool parties and baby rabbits. We’re also going to talk frankly about a super-toxic compound, because Karen would have insisted that we learn everything we can. And I know what you might think when you hear the word Karen, but let’s be fair. Karen Wetterhahn was anything but, and the Karens I’ve known have all been lovely. Don’t judge people by their name - they had no say in it. </p> <p dir="ltr">Karen Wetterhahn was born October 16, 1948, in Plattsburgh, New York. She grew into a scholar of the highest order. “She earned her bachelor's degree from St. Lawrence University in 1970 and her doctorate from Columbia University in 1975,” and joined Dartmouth in 1976, publishing “more than 85 research papers” (Wikipedia). Dartmouth later remembered her as “the founding director of Dartmouth’s Toxic Metals Superfund Research Program,” an “expert in the mechanisms of metal toxicity,” and a scholar with “expertise in biochemistry and molecular toxicology” (Dartmouth Tribute). She rose to become Dartmouth’s Albert Bradley Third Century Professor in the Sciences (Dartmouth Tribute) and in 1990 helped establish the Women in Science Project, which “helped to raise the share of women science majors from 13 to 25 percent” … and has become a national model for recruiting more ladies into STEM careers. </p> <p dir="ltr">She didn’t just research metals; she organized people. She “played an integral role in the administration of the sciences at Dartmouth,” serving as Dean of Graduate Studies, Associate Dean of the Faculty for the Sciences, and Acting Dean of the Faculty of Arts and Sciences (Dartmouth Tribute). She “trained 14 postdoctoral research associates, 20 graduate students and over 50 undergraduate research students” (Dartmouth Tribute). And she did this while building programs that actively welcomed women into the lab. She was “co-founder of Dartmouth’s Women in Science Project … and was active in the Women in Cancer Research group” (Dartmouth Tribute).</p> <p dir="ltr">Now bring in the home front—because Karen’s life was never just pipettes and publications. Neighbors remembered that “we never knew she was a world-famous scientist,” because, in Lyme, New Hampshire, “she was just Char and Leon’s mom” (The Tennessean/AP). She loved “rock music—heavy metal was her favorite,” she “tended her garden,” and she hosted some great neighborhood pool parties. (The Tennessean/AP). This is the paradox and the beauty: the same person who would lecture in Norway and Hawaii would also her drag family to the golf course and cheer at Ashley’s hockey game (The Tennessean/AP). A life in balance.</p> <p dir="ltr">On a summer day in 1996, the story turns. Karen was “studying the way mercury ions interact with DNA repair proteins” and also investigating cadmium (Wikipedia). She was using an incredibly dangerous substance that we really don’t mess with much anymore called dimethylmercury—Hg(CH₃)₂</p> <p dir="ltr">She did what a careful chemist does. She wore “safety glasses and latex gloves,” worked “in a fume cupboard,” handled “very small quantities behind the fume cupboard sash,” and the sample arrived in a “sealed glass vial” cooled in ice water to reduce volatility (Bristol “Dimethylmercury”). On August 14th, she transferred liquid and, by her own later recollection, “spilled several drops of dimethylmercury from the tip of a pipette onto her latex-gloved hand” (Wikipedia; NEJM). “Not believing herself in any immediate danger, as she was taking all recommended precautions,” she cleaned up before removing the gloves (Wikipedia).</p> <p dir="ltr">That detail—the glove—matters. Tests later showed dimethylmercury “can, in fact, rapidly permeate several kinds of latex gloves and enter the skin within about 15 seconds” (Wikipedia; Bristol “Dimethylmercury”). In other words, the glove was no barrier, but rather provided a false sense of security, like many other modern protective measures. </p> <p dir="ltr">The Tennessean would capture the image like this: “It was just a drop of liquid, just a tiny glistening drop. It glided over her glove like a jewel” (The Tennessean/AP). There’s poetry in that line, and tragedy too. The article adds: “She washed her hands, cleaned her instruments and went home. It was just a drop of liquid, just a tiny glistening drop” (The Tennessean/AP).<br /> <br /></p> <p dir="ltr">Dimethylmercury is slow, stealthy, and cumulative. It is the very definition of insidious and more perfidious than Agatha Harkness. It is “one of the most potent neurotoxins known,” crosses the blood-brain barrier, and “is a cumulative poison, being very slowly excreted from the body, and by the time its effects are noted it is too late to do anything about it” (Bristol “Dimethylmercury”). What an awful, awful sentence. Like the Blue Flash of a supercritical reaction that we discussed in our last episode, once that Dimethylmercury hits you, it’s too late…even if it takes you much slower than Gamma or neutron radiation does. </p> <p dir="ltr">For months, there were no obvious signs. Then her body started sending signals. Roughly “three months after the initial accident,” there were “brief episodes of abdominal discomfort” and “significant weight loss.” “The more distinctive neurological symptoms … including loss of balance and slurred speech, appeared in January 1997, five months after the accident” (Wikipedia). The NEJM case report—the clinical, careful voice of medicine—notes that she presented with “a five-day history of progressive deterioration in balance, gait, and speech,” after losing “6.8 kg (15 lb) over a period of two months,” with episodes of “nausea, diarrhea, and abdominal discomfort” (NEJM).  How many of us would know what caused such symptoms when they didn’t begin until 3 months after exposure?? </p> <p dir="ltr">Her own memory solved the riddle: “in August 1996 … she spilled several drops … onto the dorsum of her gloved hand” (NEJM). Hair analysis would later show a “dramatic jump in mercury levels 17 days after the initial accident, peaking at 39 days,” then a slow decline (Wikipedia). In the hospital, the numbers were grim: “whole-blood mercury, 4000 μg per liter (normal range, 1 to 8; toxic level, >200); urinary mercury, 234 μg per liter (normal range, 1 to 5; toxic level, >50)” (NEJM). That’s a lot, an awful lot of dimethyl mercury. </p> <p dir="ltr">Clinicians tried everything they reasonably could: chelation, and Vitamin E was added “as a potentially protective antioxidant” (NEJM). They even attempted exchange transfusion, and it had partial impacts, as her “mean whole-blood mercury concentration” dipped from 2230 to 1630 μg/L two hours after, only to re-equilibrate to 2070 μg/L by 16 hours (NEJM). How does that happen? I know a microgram is a tiny, tiny amount of material - 1 millionth of a gram, but that is wild to me that the mercury concentration would seemingly reduce, then come back. </p> <p dir="ltr">For reference, one sand grain weighs around 12 milligrams, or 12000 micrograms, so maybe the measurements in the 1990s weren’t the most precise, or maybe mercury levels can fluctuate. </p> <p dir="ltr">Dimethyl mercury is extremely toxic, and .1 milliliters is enough to kill you, I repeat, POINT 1 milliliters. One milliliter of water weighs one gram, and is about 1 cubic centimeter, or 10 cubic millimeters in size. .1 milliliters would be 10 percent of that size, or more like 1 cubic millimeter in size. That is small, considering a flea can be about 3 milimeters in size, and a regular black garden ant - the small kind - can grow to well over 4 milimeters long…but we’re not done yet, because dimethyl mercury is almost three times denser than water, so a drop of it big enough to kill you would be about a third the size of water of comparative mass. This means a drop of dimethly mercury large enough to kill you would be a good bit less than 1 cubic milimeter in size, provided my math is correct…a somewhat dodgy caveat. How big is that? The average size of a drop of water from an eyedropper is .05 mililiters, so - factoring in the density of dimethyl mercury, the amount that’s needed to kill you would be smaller than the drop of water from an eyedropper. Would you even notice such a small amount hitting your glove?? I probably wouldn’t. </p> <p dir="ltr">We’ve done some math there - hopefully, let’s do some chemistry now. Dimethylmercury is a liquid “with a faint sweet smell (but don’t smell it, for Heaven’s sake!),” It boils at 92°C/197.6 F (density 2.96 g/cm³ ). It’s “supertoxic,”  and it “readily crosses the blood-brain barrier,” likely via “a methylmercury-cysteine complex,” has “a high affinity for sulphur” and attacks “the thiol groups of enzymes,” inhibiting neurotransmission (Bristol “Dimethylmercury”). Clinically, symptoms include “ataxia (lack of muscle coordination), sensory disturbance and changes in mental state,” with “delayed but ultimately fatal neurotoxic effects” (Bristol “Dimethylmercury”; NEJM). The hair-mercury curve in Karen’s case soared to “almost 1100 ng per milligram,” then declined with a half-life of “74.6 days” (NEJM). Those kinetics tell a story of a toxin that builds silently and leaves reluctantly.</p> <p dir="ltr"><br /> Dr. Wetterhahn’s brain, in particular the visual and auditory cortices and the cerebellum, was profoundly injured by the mercury exposure. The mercury content in the frontal lobe and her visual cortex averaged “3.1 μg per gram (3100 ppb),” with high levels also in the liver and kidney cortex (NEJM).</p> <p dir="ltr">Outside the lab, values and scans, family and colleagues were living a vigil. The Tennessean’s account is devastating and tender. Karen—who “had never been sick, never stopped working, never complained”—now found “words … getting stuck in her throat,” “her hands tingled,” and her “whole body was moving in slow motion” (The Tennessean/AP). Friends rushed her to the hospital. After the diagnosis, “Karen beamed when she heard the news. Finally, something she understood. … Science would cure her,” she thought (The Tennessean/AP). But dimethylmercury had other plans. “Doctors didn’t know it could break down the body over the course of a few months, slowly, insidiously, irreversibly.” (The Tennessean/AP).  Like in the case with radiation accidents and Slotin and Daghlian, we learned a lot about dimethylmercury poisoning from Karen’s case. </p> <p dir="ltr">The hospital room became a command center of love and science. “E-mails flew around campus, and around the country. Students emptied libraries of books on mercury … seizing on any sliver of information” (The Tennessean/AP). Thomas Clarkson, who had studied mercury disasters, confessed: “I felt such a sense of helplessness. ‘Here was one of the world's most distinguished scientists, and I was looking at this woman dying, realizing there is nothing the scientific or medical communities can do’” (The Tennessean/AP). A colleague remembered Karen’s husband seeing “tears rolling down her face.” When asked if she was in pain, “The doctors said it didn't appear that her brain could even register pain” (Wikipedia).</p> <p dir="ltr">On February 6, “22 days after the first neurologic symptoms,” she “became unresponsive to all visual, verbal, and light-touch stimuli” (NEJM). The newspaper captures the family’s promise: in the ambulance, Karen pointed to letters“N” and “H”and “Leon nodded. He promised that, whatever the outcome, he would take her home, to New Hampshire” (The Tennessean/AP). He did.</p> <p dir="ltr">On June 8, 1997—“ten months after her initial exposure”—Karen died (Wikipedia; NEJM). </p> <p dir="ltr">Like with Daghlian and Slotin, Karen Wetterhahn’s case revealed that the safety culture around “super-toxic” chemicals needed to change, and change rapidly. “The case proved that the standard precautions at the time, all of which Wetterhahn had carefully followed, were inadequate for ‘hyper-toxic’ chemicals like dimethylmercury” (Wikipedia). Wetterhahn was not careless; she was not dramatic; she didn’t display the understandable wartime bravado of Slotin - she was doing her job soberly, with the best understanding of safety and protective gear that they had in the mid-1990s, and it just wasn’t enough. She taught us that, and probably saved many lives in the process. </p> <p dir="ltr">Back in the lab, her colleagues got empirical. They “tested various safety gloves against dimethylmercury and found that the small, apolar molecule diffuses through most of them in seconds” (Wikipedia). The Bristol write-up is direct: “it is now accepted that the only safe precaution … is to wear highly resistant laminated gloves underneath a pair of long-cuffed neoprene (or other heavy duty) gloves” (Bristol “Dimethylmercury”). In short: double up, laminate first.</p> <p dir="ltr">Her accident had a broad scientific ripple. Dimethylmercury had been “the common calibration standard for 199Hg (199 Mercury)NMR spectroscopy”<br /> What is 199 Mercury NMR Spectroscopy? I totally know off the top of my head, and if you’ll give me a second to Google it - I mean, uh, look it up, I’ll tell you. Of course, 199Hg NMR spectroscopy is a Nuclear Magnetic Resonance technique that uses the 199Hg isotope of mercury to study the structure, dynamics, and binding of mercury-containing compounds, particularly inorganic and biological complexes. And if you don’t understand that, then you probably aren’t a high-level chemist, and, uh, I can’t explain it to you. Nah, I’m just kidding. I don’t really understand precisely how they were using that isotope of 199 Mercury in NMRs either. That’s the thing about brilliant people who know their field comprehensively. The most brilliant ones can explain things so clearly that non-experts can grasp it, and I simply can’t do that, because I am not anywhere close to brilliant in this field. <br /> <br /> After Karen’s death, “the use of dimethylmercury for any purpose has been highly discouraged” (Wikipedia). The NEJM paper was blunt about the substance itself: “Dimethylmercury may be even more dangerous than methylmercury compounds,” permitting “transdermal absorption” and providing toxic exposure via inhalation; “lethal at a dose of approximately 400 mg … a few drops” (NEJM). Their conclusion: this “case illustrates the potent toxicity of dimethylmercury and the need for additional safety precautions if it is to be used in any scientific research” (NEJM).</p> <p dir="ltr">And there was legacy in people and programs. Dartmouth established “The Karen E. Wetterhahn Graduate Fellowship in Chemistry” to encourage other women in science, “whenever possible, a woman is preferred for the award” (Wikipedia). The National Institute of Environmental Health Sciences created the “Karen Wetterhahn Memorial Award,” given annually (Wikipedia). Her broader legacy, Dartmouth College notes, is in the community she built: as “founding director” of the Toxic Metals Superfund Research Program and as a dean who “helped guide the growth and development of the science division and its graduate programs” (Dartmouth Tribute). Her death “prompted consideration of using an alternative reference material for mercury NMR spectroscopy experiments” (Wikipedia). Her life prompted many to become scientists and engage in their own brave, knowledge-expanding experimentation. </p> <p dir="ltr">If after this you need a laboratory proverb to tape above your hood, try this: the only thing that should pass through your glove in fifteen seconds is regret. Everything else needs SilverShield under neoprene. As the University of Bristol writes up on Dr. Wetterhan, “Doing chemistry is safe, much safer than driving a car,” but “it is only by ceaseless vigilance and attention to safety that it remains so.” Pioneers like Wetterahn, Slotin, and Daghlian have made science safer by their sacrifice. (Bristol “Dimethylmercury”). Ceaseless vigilance is just another way of saying: love your people enough to over-protect your hands.</p> <p dir="ltr">There’s a sentence late in the AP story that won’t leave me: “In many ways, Karen Wetterhahn’s death was as important as her life” (The Tennessean/AP). That shouldn’t diminish her life, but it’s to honor her wish. “While she could still speak, she urged doctors to learn everything they could from her accident. And they did” (The Tennessean/AP). Out of that courage came data, papers, safety circulars, and—most importantly—policies that mean other scientists go home after their experiments.</p> <p dir="ltr">Her colleagues’ early ignorance of dimethylmercury’s glove permeation wasn’t negligence; it was a gap that Karen’s tragedy closed. “Wetterhahn’s accidental exposure occurred despite her having taken all measures required at that time. … her colleagues tested various safety gloves … [and] as a result, it is now recommended by OSHA to wear Silver Shield laminate gloves … while handling dimethylmercury” (Wikipedia). The NEJM article adds the sober medical coda: they could find “only three previously reported cases of poisoning with dimethylmercury, all of which were fatal” (NEJM). This is a chemical for which there is no margin.</p> <p dir="ltr">And yet, this is also a story about love—the way her husband Leon promised “New Hampshire” with two letters; the way friends filled hospital walls with photos; the way students “stayed up all night to translate obscure research papers,” riding waves of “elation … then crying” (The Tennessean/AP). It’s about a scientist who could still crack a line with the hospital psychologist. Asked if she was depressed, she smiled: “‘Wouldn’t you be?’” I appreciate the Ph.D level gallows humor there, and her bravery in the face of the unknown terrors ahead. </p> <p dir="ltr">Karen’s death galvanized institutions. OSHA guidance changed. NMR standards were reconsidered (Wikipedia). Dartmouth and NIEHS named awards in her memory (Wikipedia). Her Superfund program continued, drawing “scientists from Dartmouth College and the Geisel School of Medicine,” with collaborators from other institutions (Dartmouth Tribute). The woman who built bridges in life kept building them after, helping others cross safely.</p> <p dir="ltr">The AP article leaves us with her husband’s ongoing ache: “He still wakes in the middle of the night and wonders if it's true. He still half expects her to come striding through the door with her laptop and her notes and her smile” (The Tennessean/AP). And then there’s the photo in that article that Leon held: “Karen working in her lab, a study of intensity in her goggles and gloves, staring at her test-tubes and vials. ‘She loved her work,’ he says. ‘It made her happy’” (The Tennessean/AP).</p> <p dir="ltr">So what do we do with this story, so sad and poignant?  First, we say her name with gratitude: Dr. Karen E. Wetterhahn. Second, we adopt her final lesson like a lab oath: super-toxic chemicals demand super-protective habits. And third, we remember that safety is love in practice—because someone is waiting at home who thinks of you as more than a scientist. They think of you as Mom, or Dad, or friend, or mentor. They don’t care how elegant your NMR spectrum is if the glove fails. Maybe you aren’t a chemist, but you’d still be missed if you were gone, so be vigilant. </p> <p dir="ltr">Thank you, Dr. Karen Elizabeth Wetterhahn, teacher, builder, scientist, for teaching us to give careful thought to our ways. </p> <p dir="ltr">Next episode, we meet Dr. Anatoli Bugorski, the Soviet scientist who survived - somehow - a direct hit to the face from a particle beam fired by a giant particle accelerator. Tell your people about the show - give us some reviews or shares on social media, yeah, yeah. You know the drill.
