11 Ways We Used Radiation in Everyday Life
Radiation as a medical cure has valid uses and definite dangers to the human body. We use radiation for diagnosis (as in x-rays) and for therapy (as in cancer treatment), but the benefits must be carefully weighed against the costs. Once upon a time, radiation in different forms was new and wondrous and had a million uses -medications, cosmetics, industrial applications, and even entertainment. It was only later that the danger became evident.
1. Radioactive Toothpaste
What could possibly make your smile brighter than radioactive toothpaste? A German firm called the Auer Company (Auergesellschaft) diverted thorium supplies from the Nazi atomic program in 1944 when it became clear that Germany would not win the war. The forward-thinking company saw the future of nuclear materials in cosmetics and developed Doramad radioactive toothpaste. Besides the usual wonderful benefits of radiation, the marketing mentioned that radiation would hinder bacteria in the mouth.
2. Shoe-fitting Fluoroscope
The radiation from x-rays was not considered particularly dangerous to humans when the machine was first invented. Despite injuries to scientists and technicians, the miracle instrument found its way into doctor's offices, military labs, and even shoe stores. From the 1930s to the 1960s, children were encouraged to have their shoe size determined "scientifically" by putting their feet into an x-ray fluoroscope at the shoe store. The shoe salesman and the customer could both see the bones in the foot (and be bombarded by leaking radiation). By 1950, these machines were recognized as dangerous, but they were only gradually banned state-by-state until 1970, when remaining states restricted the machines' use so strictly that the manufacturers stopped supplying them. They continued to be used in Europe for years afterward.
3. Tho-radia Cosmetics
Dr. Alfred Curie was no relation to either Marie or Pierre Curie, but his name sold French women on the idea of radioactive cosmetics. Curie along with Alexis Moussali developed a line of beauty products under the name Tho-radia. The line included face cream, soap, powder, and even toothpaste containing thorium and radium. Although they were expensive, Tho-radia product were a hit in Paris, and therefore popular everywhere else.
Dorothy Gray Salon Cold Cream was not marketed as containing any radioactive material, but this television ad is a bit shocking to modern audiences. The model is covered with radioactive dirt to show how well the cold cream removes it. At least we hope it did.
Radithor was a cure-all patent medicine consisting of distilled water and two isotopes of radium. Advertisements called it "Perpetual Sunshine". Radithor was only one of many radioactive elixirs sold to alleviate pain and cure all manner of maladies. According to this article from 1932, a popular advocate of Radithor developed holes in his bones and skull, and his entire jaw had to be removed as it had deteriorated badly, just before he died of radiation poisoning.

5. Radium Emanators
If you needed more radioactive water than could be supplied by patent medicines, you could make your own with any of dozens of devices produced to add radiation to water. This Radium Emanator was sold in the 1930s. It had uranium embedded in the cement core, which would leach into the water overnight.
6. Radium Clock Dials
Radium paint was special in that it tended to glow in the dark. The obvious use for this was for clock dials, so they could be seen with the lights out. Young women were hired in the 1920s to paint the numbers and hands on these clocks. The painters needed a very fine point on their brushes, so they would pull the brush fibers between their lips to keep the point. The amount of radium in each clock or watch was rather weak, but the painters in the factories absorbed so much that many died of radiation poisoning and related cancers, and others suffered from various radiation-induced disorders, particularly bone loss in the jaw. Five of the "Radium Girls" sued the company, U.S. Radium for damages, a case which led to stricter safety standards for the use of radium in industry.
7. Radon Health Mines
Although natural radon emissions have been designated as a health hazard and limits of safe exposure are set, some people still believe in the health benefits of radon. For these people, a vacation to a spa just for this purpose can be arranged. These spas were opened in the 1950s at abandoned mining sites in Montana where radon seeps out in unusual amounts. Spas include the Sunshine Health Mine in Boulder, Montana and Earth Angel Health Mine in Basin, Montana. Similar facilities are open in Europe as well. Image by Landon Nordeman/National Geographic.
8. Home Experiments
The Gilbert U-238 Atomic Energy Lab was one of many children's chemistry sets that included radioactive materials, in this case four kinds of uranium. The Gilbert lab was recommended for "only boys with a great deal of education", and was priced at $50.00, an astronomical sum in those days. The high price was the reason for the disappearance of these kits rather than the danger of the materials. You could buy less expensive kits for your youngster in the sixties, such as the Atomic Energy Lab which only had one kind of uranium, but also contained radium.
In the 1930s, anyone with $150 could purchase a radiendocrinator to place over your endocrine glands to expose them to therapeutic radium. The device came with paper soaked in radium, which you inserted into the case and exposed, screen-side up, to your testicles or other glands.
10. Vita Radium Suppositories
Another way to introduce radium to your vital glands was in a suppository form. Vita Radium Suppositories were guaranteed to contain radium, which sounded like a good thing at the time. Some ads contained euphemisms such as "vitality" alluding to a promised increase in sexual potency, while other ads targeting both men and women promised global benefits for anything that ailed you.
11. Uranium Glass
Beginning around 200 years ago, uranium salts were combined with silica before it was melted to create pretty yellow-green glass dishes. Most of these uranium glass dishes are valuable antiques now, and this is why you may see people carry black lights into an antique shop or flea market -they are testing for actual uranium content as opposed to later recreations.
