These Everyday Items Were Dosed With Radium Until We Discovered It Was Toxic

Radium was discovered by Marie Curie and her husband Pierre in 1898.In 1903, the Royal Academy of Sciences awarded Marie and Pierre Curie and Henri Becquerel the Nobel Prize in Physics, making Marie the first woman to win the prize.

Later, in 1911, she would win her second Nobel for isolating radium, discovering another element (polonium), and for her research into the new phenomenon of radioactivity, a word she coined herself.

By 1910, radium was manufactured synthetically in the U.S. But before the effects of radiation exposure were well understood, radium ended up in a lot of crazy places for its purported magical healing properties and its glow-in-the-dark novelty.

1. In Chocolate

Food products containing radium, like the Radium Schokolade chocolate bar manufactured by Burk & Braun and Hippman-Blach bakery's Radium Bread, made with radium water, were popular overseas until they were discontinued in 1936.

2. In Water

Radium water crocks like the Revigator stored a gallon of water inside a radium-laced bucket; drinking the water would cure any number of ailments, from arthritis to impotence to wrinkles.

3. In Toys And Nightlights

4. In Toothpaste

Toothpaste containing both radium and thorium was sold by a man named Dr. Alfred Curie, who was not related to Marie or Pierre but didn't miss an opportunity to capitalise on their name.

5. In Cosmetics

Alfred Curie's product line didn't end with dental care, though. He also manufactured the extremely popular Tho-Radia brand of cosmetics, which included powders and creams that promised to rejuvenate and brighten the skin.

6. In Heating Pads And Suppositories

7. In The Treatment Of Impotence

8. In Health Spas

9. In Clocks And Watches

Between 1917 and 1926, during the height of radium's heyday, the U.S. Radium Corporation employed more than a hundred workers (mostly women) to paint watch and clock faces with their patented Undark luminous paint. As many as 70 women were hired to mix the Undark paint, comprised of glue, water and radium powder. Workers were taught to shape paintbrushes with their mouths to maintain a fine point, and some used the material to paint their nails and teeth. While U.S. Radium's labour force were all but encouraged to ingest the dangerous mixture, management and research scientists who were aware of the danger carefully avoided any exposure themselves.

Five Radium Girls sued U.S. Radium in a case that initiated labour safety standards and workers' rights. There are no records of how many of U.S. Radium's employees suffered from anemia, inexplicable bone fractures, bleeding gums and eventually, necrosis of the jaw. Though many of the factory's workers became sick, cases of death by radiation sickness were initially attributed to syphilis. (It's believed that this was an attempt to smear the girls' reputations, and that medical investigators hired by U.S. Radium were paid to withhold their findings.)

The Radium Girls' case was settled in 1928, putting a swift end to shaping paintbrushes with the mouth and open containers of radium paint. Though radium was still used in clocks until the 1960s, new cases of acute radiation syndrome in dial painters came to a screeching halt, and soon after, so did the popularity of radium-containing products and toys. The former U.S. Radium manufacturing plant is now a Superfund site.
