The Canadian Radiation Protection Association (CRPA) was officially formed in 1979. Prior to that time, Canadians who were involved in radiation protection were for the most part members of the Health Physics Society (HPS), which is the official body for radiation protection professionals in the United States.
Throughout the late sixties and early seventies the number of Canadians working or interested in some aspect of health physics increased, until there were more than 80 Canadian members in the HPS. This was more than the membership of half of the countries that were members of the International Radiation Protection Association (IRPA). With these increasing numbers, it became more and more desirable to have a forum for discussing or establishing a collective viewpoint on Canadian topics in radiological protection.
In late 1977, Richard Osborne sent a questionnaire to the Canadian members of the Health Physics Society asking whether the formation of a Canadian group should be attempted. The questionnaire elicited 119 enthusiastic responses, with the majority favouring a technical/scientific-based society, primarily concerned with radiological protection and organized to be independent of other Societies.
Using these replies as a guide, a small group went ahead with organizing the formation meeting in Toronto, which took place on 27th April 1979. Efforts were made to ensure that participants were gathered from as many provinces as possible and from the many disciplines and activities associated with radiological protection, including industry, government, universities, hospitals, nuclear utilities and R&D laboratories. Ultimately, 89 people approved a draft constitution and indicated their intent to join a newly formed Canadian Radiation Protection Association. Later that year, on October 26th, 1979, with 48 full members the CRPA successfully applied to become an Associate Society of the International Radiation Protection Association.
The CRPA became officially incorporated in 1982.
CRPA has over 300 members from all areas of industry including hospitals and health care, universities, nuclear power and mining industries, regulatory bodies and all levels of government. 95% of our members are from within Canada and 5% are international, including members from Australia, Europe, and the U.S.
Membership categories include:
The objective of the Canadian Radiation Protection Association (CRPA) is to advance the development and communication of scientific knowledge and practical means for protecting people and their environment from the harmful effects of radiation consistent with the optimal use of radiation for the benefit of society. To this end, CRPA will:
