The Radiation Safety Institute of Canada was founded in 1980 in response to the disaster in Elliot Lake, where over 200 uranium miners died of lung cancer after being exposed to radioactive radon gas and long lived radioactive dust. It is a not-for-profit independent national organization dedicated to prevention of cancers resulting from unacceptable exposure to radiation, and works to promote radiation safety in the workplace, in the home and in the environment in Canada and internationally.
