Doramad Radioactive Toothpaste
Doramad Radioactive Toothpaste (Doramad Radioaktive Zahncreme) was produced in Germany by Auergesellschaft of Berlin from the 1920s through World War II.[1]
Development
The toothpaste was slightly radioactive because it contained small amounts of thorium obtained from monazite sands.[1][2] Auergesellschaft used thorium and rare earths in making industrial products including mantles for gas lanterns; the toothpaste was produced as a byproduct.[1] Its radioactive content was promoted as imparting health benefits, including antibacterial action and a contribution to strengthening the "defenses of teeth and gums".[1][2]
