Until about 1915 these were called Sinclair Hot Springs. An analysis of the water was made at McGill University 14 May 1912, and it was discovered to contained radioactive particles - hence the change of name. "The natural temperature of the main spring of the Sinclair/Radium Hot Springs in Kootenay National Park....is about 114 degrees Fahrenheit. The radioactivity is unusually high and it is believed that their theraputic efficacy may be partly due to this fact" ("Natural Resources", Canada, July 1929).
