The craze came to an end when then-famous industrialist Eben Byers developed cancer of the jaw and died after using Radithor for several years, causing bioaccumulation of radium in his bones. Most of his teeth had come out, most of his jaw had to be removed, and other bones in his body were disintegrating.

There was also the famous case of the Radium Dial Painters in the US and Canada, who suffered similar fates after being told to use their mouths to shape camel hair brushes used to paint radium dials. 50 became sick, a dozen died from radiation poisoning.
