The Power of Radium – Health & Medicine in American History
The residue of radium ore was even used as sand in children's play boxes [17]. Stores sold portable, small size devices known as water jars that produced radioactive water good for any "common ailment" that one could imagine. Those jars guaranteed that the produced radioactive water "aids nature" and works as natural "vitalizer" [18].

EPA Facts about Radium
Isotopes of radium decay to form radioactive isotopes of radon gas. The time required for a radioactive substance to lose 50 percent of its radioactivity by decay is known as the half-life. The half lives are 3.5 days for radium-224, 1,600 years for radium-226, and 6.7 years for radium-228, the most common isotopes of radium, after

Management of wastes from uranium mines and mills
As at least 97% of the Ra-226 fed to the mill remains undissolved through the leaching process, the concentration of radium in the tailings is only slightly less than that in the ore. Radon will be continually produced because of this Ra-226 in the tailings. Whereas windborne particulates from the tailings' surface may be
