Radium Emanatorium

The album photo caption reads: "Exterior View - Standard Radium Emanatorium capable of treating ten persons at one time." The concept was that the inhalation of the radon produced by the decay of radium would have medical benefits. Until 1930 or so, radon was commonly known as radium emanation. These types of treatments were promoted by the director of Standard Chemical's medical clinic, William Cameron. Cameron and Charles Viol, a colleague at Standard Chemical, founded the American Radium Society.
