 Radon inhalation rooms were set up, where air tubes carried the gas up from a processing tank in the basement; the visitor would then use it through an inhalation apparatus.Baths were set up which were also irradiated, and irradiated air was also filtered through a trumpet-like pipe for inhalation.Concerns about radium were brought up before the United States Senate by California Senator John D. Works as early as 1915.
