Who Knew?

False teeth are often radioactive. Approximately 1 million Americans wear some form of denture; half of these dentures are made of a porcelain compound laced with minute amounts of uranium to stimulate fluorescence. Without the uranium additive, the dentures would be a dull green color when seen under artificial light.
