Radithor

The time of Radithor and radioactive elixirs ended in 1932, with the premature death of one of its most fervent users, Eben Byers, an American golfer.

[5] Byers was buried in a lead-lined coffin; when exhumed in 1965 for study, his remains were still radioactive and measured at 225,000 becquerels.

[4] As a comparison, the roughly 0.0169 g of potassium-40 present in a typical human body produces approximately 4,400 becquerels.

[6] His death led to the strengthening of the Food and Drug Administration's powers and the demise of most radiation-based patent medicines.

A Wall Street Journal article describing the Byers incident (published in August 1990) was titled "The Radium Water Worked Fine Until His Jaw Came Off".
