The Radium Water Worked Fine Until His Jaw Came Off
—Headline run by The Wall Street Journal about the death of Eben ByersWikipedia.

Radium (Ra) is an extremely radioactive metal (much more radioactive than an equal mass of uranium), producing all three kinds of ionizing radiation — alpha-, beta- and gamma-. It occurs naturally, as it is a result of the decay of uranium, and in turn decays into radon (Rn) — "a radioactive, colorless, odorless, tasteless noble gas" according to Wikipedia. Sounds fun, unless your house is built on granite bedrock (which contains uranium). Radium and radon have no stable isotopes, and as with all types of ionizing radiation, they can cause cancer to people who are exposed to them. radium-224, radium-226, radium-228 and radon-222 are known to be human carcinogens.[1]

Radium and radon quackery[edit]

Got a headache? Try some Tho-Radia — we use only the best radium and thorium!

Radium was first isolated in the beginning of the 20th century. About the same time it was found that the waters of several popular mineral springs were radioactive, as they contained "radium emanation" - a.k.a radon. The medical science of the time added two and two, forgot to subtract one thousand, and got four:

—Dr. C.G. Davis, the American Journal of Clinical Medicine

As a result, an industry of radium- and radon-related products sprang up. People were not content with bathing in and drinking natural radioactive water at the springs and decided that they need to do it at home (radon decays relatively quickly so radon water can't be transported over long distances).

A sample breakdown:

  • Various "radium emanators" and "radium jars" — water vessels for enriching water with radon. Some of them used porous ceramic containing radium or uranium; others were made of vaseline glass — normal glass coloured in a lovely yellow hue by adding uranium (exposed to UV light, it gives out an almost cartoonish radioactive green glow). Note that normal uranium glass is not very radioactive.
  • Some smartass took the idea further and produced a soda syphon that used bulbs containing radon in addition to the carbon dioxide
  • Bread made with radium water, because why stop at medical woo when you can have food woo too?[2]
  • Radium tablets shouldn't be surprising by now, but what about radium suppositories?
  • The crown of utmost radium idiocy goes to the guy who made a belt holding shiny capsules of radium-soaked paper under the wearer's testicles. He was an enthusiastic user of radium products. He died of bladder cancer.

Despite the "radiophobia" that gripped the West (and the East) after the bombing of Hiroshima and Nagasaki and the MAD days of the Cold War, radioactive "health" products, including radium and radon products, are still manufactured and marketed. If you want to bathe in radon-enriched water, some Japanese guys will sell you the Radon Egg — a ceramic container in which thorium tablets will release radon in your tub before the bath.[3]

One of the reasons the FDA was created was to crack down on radioactive quackery.

Non-quack uses of radium[edit]

Radium was used in the first successful radiotherapy treatment for cancer, originated by Marie Curie (whose death can be unmistakably attributed to radiation exposure itself). Thin metal cylinders filled with milligram amounts of radium salts, called "radium needles", were surgically implanted into cancer tissue and then removed after some time. This technique, called brachytherapy, is a legitimate medical procedure that is still used today. The radium salts, however, have largely been replaced by cheaper alternative isotopes, produced in nuclear reactors. It was at one time used to reduce the size of an overactive thyroid.

Another notable use of radium was in luminous paint used on watch hands, instrument dials, control panels and other equipment that had to remain usable in the dark without electricity. Many of the workers who painted the dials ended up with severe health problems, especially in the mouth as they were told to lick the paint brushes. This led to a coverup on the employers' end, with them trying to fund studies that would show that radium was safe, but eventually the evidence that radium was dangerous was too obvious and they had to stop.[4] Due to radium's long half-life, cost and gamma emissions, it has been replaced in this role with promethium, and then tritium, which emit only low-energy beta particles and are therefore only dangerous when ingested. Today, almost no household glow-in-the-dark wristwatch dials or toys are made with radioactive substances at all; instead they rely on slow phosphorescence, the absorption and slow re-emission of ordinary light, which is why they typically only glow for a few minutes after you turn the lights out. Furthermore, LEDs have largely supplanted the original need for glow-in-the-dark paint.
