Tritium Hazard Report: Pollution and Radiation Risk from Canadian Nuclear Facilities

Publication - June 11, 2007
The report concludes that official attitudes on tritium are unscientific and incorrect, that tritium’s hazardous nature should be fully acknowledged by radiation protection agencies in Canada, and that tritium’s dose coefficient should be increased substantially.

Executive summary: This report on tritium releases in Canada is in two parts. Part 1 discusses tritium discharges from nuclear facilities in Canada and compares them with those from reactors in other countries. It examines the resulting tritium concentrations in drinking water, air and in food near Canadian nuclear stations. Although tritium releases from Candu facilities are very large, radiation protection regulators continue to maintain that these releases are of little concern because tritium’s radiation doses and its resulting hazards are small. Part 2 examines these contentions in considerable detail. It shows that tritium’s radiation “doses” are, questionably, estimated to be several hundreds of times lower than most other radioactive elements. Radiation and radioactivity (including risks, doses, biology and epidemiology) are complex matters which are often difficult to grasp. Therefore Part 2 is designed to be read primarily by health physicists and radiation protection scientists. However, efforts have been made to make this report more accessible to the wider public. In particular, technical terms have been explained and scientific jargon has been avoided. The report concludes that official attitudes on tritium are unscientific and incorrect, that tritium’s hazardous nature should be fully acknowledged by radiation protection agencies in Canada, and that tritium’s dose coefficient should be increased substantially
