Once an estimate of the quantity of tritium in the body is made, the dose can be calculated by using biological models that estimate the concentration of tritium in organs and tissues. [...] The goal of the project was to enhance the information available to guide regulatory oversight of tritium processing and tritium releases in Canada. [...] The regulation of the impacts of tritium releases are within the mandate of the CNSC, through the Nuclear Safety and Control Act (NSCA). [...] Overall, the study aimed to contribute to our knowledge of the pathways and mechanisms of transformation of tritium emissions from nuclear activities to the biosphere and the food supply. [...] Figure 3. T ritium dose to members of the public in 2006 compared to the dose from all radionuclides and the CNSC public dose limit (with the dose due to tritium as a percent of the public dose limit shown on the x-axis) 1,000.
