86. Radon: It’s Coming From Inside The House

You know something’s amiss when you set off the radiation alarms while walking in to the nuclear power plant.

Show Notes

Back in the 16th century, lung disease was a problem in a Bohemian town called Joachimsthal, meaning “St. Joachim’s Valley” in German. There wasn’t much there aside from the mines, but it’s one of those out-of-the-way places that’s had a surprisingly outsized historical impact. For instance, the silver coins minted there were called “Joachimsthalers,” which understandably got shortened to “thalers.” Given a few centuries to marinate, this became “dollar.”

It’s a weirdly influential town in that kind of way. The other medieval mineralogist, Georgius Agricola, also spent some time there studying. Hundreds of years later, so did J. Robert Oppenheimer, AKA “The Father Of The Nuclear Bomb.” (Or as I like to call him, Atom Daddy.) The Nazis appear to have had a sickening interest in the place, and for a time, there was fear that they were using uranium from the mine to build their own atomic bomb.

That is what the Soviets did with the place after Joseph Stalin negotiated the rights to the place. Political prisoners dug uranium out of the dirt there until 1960.

Additionally, Joachimsthal is part of Czechia now, and its name has changed. Please forgive me, but I just couldn’t say its new name in audio format: Jáchymov.

I checked multiple independent sources for the correct pronunciation. The J takes on a Y sound, but even so.

I apologize to the good irradiated people of Jáchymov for my anglocentric immaturity.

In researching the Watras incident, I came upon this news story. I didn’t end up using anything from it, but I love the lede, which is just a huge swing and a miss: “If Stanley Watras’ home were a uranium mine, it would have been closed long ago.”

get it. And it’s kind of clever and cute, but it’s overruled by its own clunky absurdity. If Stanley Watras’ home were a uranium mine, I would have many more questions before thinking about Health & Safety.

One of the coolest things I stumbled upon but didn’t get a chance to include: It’s possible that monitoring radon could be a tool for predicting earthquakes. The idea is that tectonic plates that are about to slip are likely to suddenly emit lots of radon gas.

Strangely, it doesn’t appear that much research has gone into this beyond the preliminary stage. Geologists, what’s the word?

Episode Script

Radon is one of the noble gases; thus, its valence shell is full and it’s nearly entirely unreactive. But that doesn’t make it safe. Quite the opposite, actually. While radon hangs on to its electrons tightly, it’s prone to spontaneously ejecting bits of its nucleus as alpha radiation — and as we’ve recently learned, that stuff can kill you.

So if radon is noble, it’s distinctly a Prince-of-Denmark kind of nobility — a fittingly dramatic way to cap off period 6 and Poisoner’s Corridor.

You’re listening to The Episodic Table Of Elements, and I’m T. R. Appleton. Each episode, we take a look at the fascinating true stories behind one element on the periodic table.

Today, we’ll pluck radon from thin air.

Even among the weird radioactive elements near the bottom of the periodic table, radon stands out in its oddness. Many of the upcoming elements are laboratory curiosities, often existing only for brief moments in time, with no place in the natural world. Some of them have changed the course of history, but only after humanity found ways to exploit them.

Conversely, radon is everywhere on Earth, and it always has been. In minuscule amounts, granted, but the entire time, it’s been exercising influence over us and all known life from the very beginning.

We really started from the bottom: as single-celled prokaryotes hovering near hydrothermal vents on the sea floor. Now we here: trillions of cells acting in concert to metabolize, locomote, and wear every single chain, even when we’re in the house.

Every step of that journey was driven by genetic mutation — slight changes to our DNA, the blueprints to our bodies. Sometimes these cause disabilities, or cancers, but once in a great while, that slight tweak to its DNA will benefit an organism, making it more likely to survive and pass that DNA down to the next generation. The accumulation and development of these changes over time is what we call “evolution.”1

When the subject comes up, most of the focus tends to be on the changes. That makes sense, that’s where all the interesting stuff happens, the results of those genetic mutations. But the causes of those mutations are just as critical.

Mutations can occur spontaneously, through sexual reproduction or errors in DNA replication, but if that were the only thing driving evolution, the process would be even slower than it already is.

Plenty of chemicals can have an effect on DNA molecules when ingested, from cadmium to polycyclic aromatic hydrocarbons. But mutagens aren’t only chemical in nature. Bacteria and viruses can alter DNA, and so can ultraviolet light, x-rays, and even cosmic rays from distant stars. You may have noticed those last three are all types of radiation, and the alpha radiation emitted by radon is quite capable of doing the same thing.2

Whenever polonium decays into lead, bismuth, thallium, etc., that all tends to happen in one place. Those elements are usually solids, so they’re not exactly mobile. But when an unstable atom decays into radon, it’s freed from its earthly shackles and can float off into the atmosphere.

Around sea level, there’s pretty reliably about 2,500 atoms of radon per cubic inch. That’s out of the many quintillions of atoms occupying that cubic inch — it’s an infinitesimal amount of radon that we’re talking about, but it is a pretty constant level and it’s pretty well dispersed around the globe.3 4 5

The theory proposes that this omnipresence has made radon one of the most reliable and consistent mutagens on Earth, wielding only minuscule influence over DNA, but doing so constantly for billions of years.6

It’s worth noting that this isn’t a “good” thing. Mutations can be as harmful to an organism as they can be helpful. And on the timescale of a human life, as opposed to the speed at which evolution operates, radon’s effects can be fatal. In this way, humanity was familiar with the effects of radon for centuries before discovering radon itself.

Remember Paracelsus, the 16th-century doctor slash philosopher slash alchemist who taught us that “the dose makes the poison”? In 1537, he noted the incredibly high occurrence of “Schneeberger Lung Disease” among local miners. This was different from any of the myriad other lung diseases plaguing miners, especially with its high mortality rate and frequent occurrence among young miners, rather than those who had been working the mines for decades.7 8 9

Paracelsus figured this had something to do with the bad quality of the air in the mines, possibly because of thick dust. He was on the right track, but not quite correct. This disease was lung cancer, and a main cause was the presence of radon gas. Workers at the time were mining silver; unbeknownst to them, those veins were also rich in uranium, which eventually decays into radon.10

Radon would remain unknown until the turn of the twentieth century, and even its discovery was unusual compared to its elemental neighbors.

Whereas polonium, actinium, and radium were found by element hunters sifting through highly radioactive ores, nobody really went looking for radon. And when it finally was found, no one thought it was an element!

The Curies had figured out that radium was giving off some kind of gas, and that said gas remained radioactive for long periods of time. Ernest Rutherford found the same thing while studying thorium. He referred to the gas as “thorium emanations.” It looked a lot like a new element, and behaved like one, too… but these were the pioneering days of radioactive science, and the idea of one element transmuting into another sounded downright preposterous.11 12

Incidentally, Rutherford was assisted in this work a great deal by Harriet Brooks, Canada’s first female nuclear physicist. She was regarded as one of the brightest minds in physics, and is another of the many unsung women in science history.13 Whenever he had the chance, Rutherford always spoke glowingly of her, if you’ll pardon the pun. In a recommendation letter for a fellowship, Rutherford said, “next to Mme. Curie she is the most prominent woman physicist in the department of radioactivity.” In a personal letter to a colleague, he called Brooks “a woman of great personal charm and marked intellectual interests.”14 And when she died at the young age of 56 — possibly because of her work with radioactive elements — Rutherford wrote an obituary for Nature that emphasized the foundational importance of her work “to the then youthful science of radioactivity.”

Rutherford was also quick to note that the Curies played a big part in this work. In general, he seems to have been the kind of guy who genuinely wished to give credit where credit was due. Make no mistake, though — Rutherford did have an ego. He was competing quite fiercely with noble gas superstar William Ramsay in his study of these emanations, and he didn’t think very highly of Ramsay’s work. In 1908, he succeeded in developing a photograph of radium-emanation’s chemical spectrum. Ramsay claimed to have done the same, but Rutherford thought he was full of bull-emanations — and he was quite pleased at the thought of getting one over on old Ramsay. In a letter, he wrote, “I think [my colleague] Royds and I have certainly succeeded in making Ramsay temporally very unhappy.” Or, as renowned chemist Sir Martyn Poliakoff so delightfully puts it:

I just think it’s so wonderful. We always think of these scientists from the past as being saints. And here he is in his office thinking, ‘Hee hee, I’ve made my competitor feel uncomfortable!'”15

Anyway, it soon became difficult to deny that this was, indeed, a new element. For Ramsay’s part, he published the following:

«emanation from radium», … is a cumbrous expression, and sufficient evidence has now been accumulated that it is an element… It is true that it is only a transient element, and ought in justice to be called a compound; but of what? It stands on a wholly different plane to any known compound (…) It is a gas; it follows Boyle’s law; (…) it resembles the gases of the argon series in its indifference to chemical reagents (…) Now, it appears advisable to devise a name which should recall its source, AND … express the radical difference which undoubtedly exists between it and other elements. As it is derived from radium, why not name it simply «exradio»?”

Ooo, so close.

Ramsay also proposed “exthorio” and “exactinio” for those emanations coming from thorium and actinium. When those names didn’t catch on, Ramsay said, “Okay, how about ‘niton,’ from the Latin for ‘shining?'” This too was met with a collective “meh,” and these substances continued to be called “radium emanation” and such for 13 more years.

In 1923, predecessors to the IUPAC chose the names radon, thoron, and actinon. These were all isotopes of the same element, though, and since naming every isotope got rather cumbersome rather quickly, they were all filed under the name “radon.” (Radon-222, radon-220, and radon 219, to be precise.)

Brooks and Curie and all the other pioneers of radiation couldn’t possibly have known that this newly discovered phenomenon could lead to their demise decades later — but the rest of us learned quickly. Now we keep safety standards in place for those who work closely with radioactive substances. For instance, in 1984, Pennsylvania’s Limerick nuclear reactor installed alarms that would sound if any employees leaving the site seemed to be dangerously irradiated.

So everyone was very confused when construction engineer Stanley Watras set off those alarms, sirens blaring and red lights flashing. Confused because Watras wasn’t leaving the plant — he had just shown up for another day on the job. What’s weirder is that the site was still under construction, so there wasn’t even any nuclear fuel there yet.

Watras had come straight from home, so investigators checked that first — and almost immediately found the problem. As you can probably guess, it was radon. Lots of radon. The air in the Watras’ home was reading radiation levels 700 times greater than the safe limit for human exposure. As the Chicago Tribune put it at the time, Watras and his family were nearly seven times as likely as an average person to get lung cancer in the following decade.16 In terms of exposure, it was as though they had all been smoking several hundred packs of cigarettes every day17 — because of course there’s radon in cigarettes. Cigarettes are the hall of fame of chemical poisons, wrapped up in convenient tube form.18 19

So how did the radon get in Watras’ house? The same way that it usually escapes into the atmosphere. It seeped into the basement from the rocks beneath the house — and once it got there, it wasn’t going anywhere.20

The problem is that radon is quite heavy for a gas — its atomic number is 86, after all. So without deliberately venting the gas outdoors, the radon just kind of pools up at the lowest point it can find. By the way, that was the solution for the Watras house — a strategically placed duct and a decent fan were all that it it took to lower radon back down to safe levels. There might be such a contraption in your own home, too. It mostly depends on where you are and the hyperlocal geology beneath your abode. Domestic radon isn’t a terribly common problem, but it is common enough to support a thriving radon testing and mitigation industry.21

Radon is a known carcinogen, and we generally go to great lengths to limit our exposure. So it’s especially baffling that some people willingly, even joyfully pump it into their bodies.22 23 No, I’m not playing coy about cigarettes again. Astoundingly, there are several places around the world where clients can be exposed to relatively high levels of radon. (Not as much as was in the Watras house, but much higher than the EPA’s safe limit.) These “radon spas” can be found in Ukraine, Czechia, Austria, and Montana, among other places.24 Proponents claim that radium has anti-inflammatory and painkilling properties that work when nothing else will (although plenty of people also casually claim that this treatment can deepen sleep, lower cholesterol, and cure infertility).25 26 27 28

Countless anecdotes can be found in support of this kind of radon exposure, but scientific evidence is scant, when it’s not outright contradictory.29 30 31 32

Still, it’s possible these passionate enthusiasts could be on to something. The amount of radon the EPA considers acceptable is very, very low, so it’s possible that slightly elevated levels of radon might not be very hazardous. Paracelsus might utter his perpetual refrain, and there are plenty of people who have endured such exposure to no visible ill effect.33

In fact, Stanley Watras and his family seem to be among them. Reliable information is hard to come by, but it seems that he’s still with us and doing just fine.. In 1997, he appeared in a PBS FRONTLINE documentary about nuclear power, and public records suggest that he’s still alive and voting in Pennsylvania.34

Despite all that, I will formally recommend that you not collect radium at densities above 4 picocuries per liter. If you laugh and flout this suggestion, being the rebel you are, there are a few ways you could collect a sizable sample of this noble gas.

It is occasionally used in oncological treatment, making it one of those strange elements that can be the cause of and solution to cancer. Sometimes it’s even delivered via little vessels of pure gold.35

But if aesthetics matter to you the handsomest way to collect radon is probably by acquiring an antique watch that has (or had) numbers on its face that provide their own light. Those watches were painted with a special paint that contained radium and… well, we’re going to hear all about that very soon. For now, I’ll just say those watches are still emanating radon today, and leave it at that.36

And that’s the trick. Like so many of the upcoming elements, radon has a pretty short half-life — a little over three days. That means you don’t want a vial of radon, you want something that will continuously emanate radon as it decays. Perhaps you’re sitting atop such a source right now. You’d certainly surprise the contractor conducting your radon test if its failure put a big smile on your face.

Perhaps I’ll get a little more adventurous in the future, but for now, I’ll be satisfied with the trace amounts that exist in the air near my element collection. There might not be very many of them, but they are there, and they’re very important.

    1. Oganesson seems to have the properties of a noble gas, but it’s hard to know for sure, since it’s so short-lived. Theoretically, it’s possible that there could be other ultra-heavy noble gases!

  1. Wait, chimera refers to a specific composite creature, not just any composite creature?

    Also, I just realized, but Period 7 will be the first period where I’m listening to episodes as they come out(I caught up with my initial binge around the time you started the Lanthanides… Of course, just because we’re entering the last period doesn’t mean we’re in the home stretch quite yet, more than a fourth of all elements are in the last row of the table… at least until Element 119 is synthesized and period 8 gets started, assuming Ununenium(or is it Ununnonium? I might have my greek and latin prefixes mixed up) doesn’t completely destroy predictions of how super heavy elements behave.

    1. Both, kind of! I think mythological chimerae tend to at least follow a certain template, where there are multiple heads and the main body is probably a lion’s and the tail is some kind of snake, but there’s a lot of variability among what species the heads belong to, whether there are wings involved, etc. But yeah, in the scientific realm, I think it’s a lot more general term referring to one animal’s peanut butter getting mixed into another one’s chocolate.

      I have to admit, I do kind of hope there’s a boom of elemental discovery in the next year. That, or none at all, so as to preserve the finicky tidiness of seven perfectly filled rows. The worst will be if 119 is the only one they discover.

      1. The Ancients really like their Lion-hybrids… setting aside the inconsistent depictions of chimeras(chimeri? is the word of Greek or Latin origin and which is it that uses the odd by English standards plural form?), We have, at a minimum, Gryphons(and the multitude of spelling variants), Sphinxes, and manticores, though two of those are part bird, one is part primate, and one is part arthropod in their most familiar depictions… Though I have read stories where gryphons with snakes for tails(and the snake head having a separate mind and personality from the Lion head) treated like a legendary form of mundane Gryphons…

        And yeah, it was messy enough seeing versions of the periodic table where there were gaps in the hundred teens after growing up with tablesthat had started with 109 elements with 104+ with systematic names that then slowly added the real names and adding the hundred preteens in order… Period 8 is going to make a mess of things… and is going to last a long time… I forget the exact numbers, but isn’t it predicted that the g-block will have so many elements that Period 8 will add like another hundred elements by the time we get to Eka-Oganesson? And isn’t it predicted that electrons would need superluminal orbital speeds to avoid crashing into the Nucleus by the time we reach element 137?

  2. Well everyone knows of sharks and rays, but few people ever heard about the chimaeras outside of marine biology

  3. So how would I have to modify my periodic table shawl to accommodate a g block? It would already be weird enough to have an Element 119 square dangling off the bottom left of my shawl.

    1. Well, first to review the existing blocks, just in case anyone is unfamiliar:

      The blocks are named for the type of orbital that is filled by the newly added electron in the element’s neutral electron configuartion: s, p, d, and f.

      In a given period, the s orbital is the first to be filled and can hold two electrons, so the s-block consists of the two leftmost columns of the standard table, plus Hydrogen and Helium, which are both put on the left on tables emphasizing the electron configuration blocks.

      Next to be filled are the p-orbitals, which hold a total of 6 electrons, and the p-block is the six rightmost columns of the standard table, minus Hydrogen and Helium. Together, the s and p electrons form the Octet of the Octet rule.

      d-orbitals hold ten electrons and the d-block is the low, middle section of the standard table.

      The f-orbitals hold 14 electrons, and the f-block consists of the Lantanides and Actinides(sorry if those are misspelled, Firefox is flagging them, but isn’t suggesting anything that sounds more correct as my screen reader reads them to me). The Standard tableseparates the f-block from the main table and puts them below, though there are versions that insert them in-line, leading to a very long, short wall between the s-block tower and the rest of the table. The version with the separated f-block probably gained dominance at least in part because it makes printing the tablein landscape on a single sheet of paper with a typical aspect ratio manageable(the in-line version is nearly twice as wide, after all).

      Based on existing trends, it’s predicted period 8 will start filling a fifth orbital type, and based on the pattern, I believe it’s predicted that 18 electrons will be required to fill this new orbital… if the current standard form of the table survives the population of period 8, I suspect the g-block willend up detached and displayed below the f-block… I believe the prediction based on trends is that Unbiunium will be the first g-block element, and I wouldn’t be surprised if someone has already nicknamed the period 8 g-block elements the unbiunides and totally expect both g-block and the third row of the f-block to get nicknames similar to the ones we already have for the existing rows of the f-block.

      That said, Period 7 already shows some break down of periodic trends, most of the period 7 elements have never been synthesized in macroscopic quantities, and of the ones that have, I’m fairly sure most have never been found in nature. Plus, Period 8 brings up lots of questions that could potentially break electrons from their predicted behavior(such as if the innermost electrons can move fast enough to not crash into the nucleus due to strong charge attraction, whether enough of a nucleus’s positive charge can penetrate such thick electron clouds to hold on to the outermost electrons, and I’m sure there are ones I’m forgetting or haven’t heard of), so period 8 could go completely off the rails and defy all predictions to electron configuration, assuming such super heavy nuclei can even be long-lived enough for scientists to observe their electron clouds sufficiently.

      Though, thinking about how period 8 might break the current standard form of the periodic table, it makes me wonder how long the current standard form has been standard. I remember middle school science classes in the late-90s having textbooks that might have been old then that featured a version of the table most people would find familiar that only listed 109 elements and I think had systematic, placeholder names for Elements 104-109… and I know Mendeleev’s table bares little resemblance to modern versions(granted, he only had atomic masses and bulk properties to go on, atomic number and subatomic particles came later).

      1. I’ve been meaning to respond to this and your other comments for several days now, and I’m sorry to not reply with more substance, but — this is such a fantastic and comprehensive explanation of such a mind-boggling topic. Orbitals stand at the gate of the truly mystifying, and while it gets a lot weirder down there, orbitals are a good warning to “abandon all hope if this isn’t your cup of tea.”

        Thank you so much for sharing all of this! If it’s all right with you, I think I might highlight this in a post of its own so that others can more easily find it.

        1. I’d be happy for you to highlight any of my comments if you think them worth highlighting.

          Though I confess, I barely understand orbitals myself beyond “electron clouds are much stranger than the planetary model of the atom or a series of concentric spheres”, that each orbital has a number of suborbitals that each contain a pair of electrons with opposite spin(another term that means something much stranger when talking atoms and their components than talking macroscopic objects), and that s orbitals are roughly spherical and p orbitals form 3 mutually orthogonal pairs of teardrops.

          Though, speaking of strangeness, I kind of wonder why Strange quarks get all the attention when talking the more exotic parts of the Standard Model… Top and Bottom quarks are another generation up and thus require more extreme conditions to exist for any sizeable length of time, but you’d think charm quarks would get more attention.
