Tritium Releases and Dose Consequences in Canada in 2006

The Tritium Releases and Dose Consequences in Canada in 2006 report (PDF) is one of a series of research studies being produced by the Canadian Nuclear Safety Commission (CNSC) under its Tritium Studies Project.  The goal of the research is to expand the body of knowledge on tritium and to further enhance regulatory oversight of tritium-related activities in Canada.

The study reports that:

  • releases of tritium from nuclear facilities in 2006 were a small fraction of the regulatory limits
  • doses to workers or members of the public living near nuclear facilities were a fraction of the CNSC dose limits
  • concentrations of tritium in drinking water sources around nuclear facilities were all below the Canadian drinking water quality guideline of 7,000 becquerels per litre (Bq/l)
  • elevated levels of tritium in groundwater do not contribute to the radiation dose of workers or the public
