Methodology for estimating radiation doses due to tritium and radiocarbon releases. [Health hazards from thermonuclear reactors]
Although the exact release rates of tritium (/sup 3/H) and /sup 14/C to the environment from a fusion power plant are not known, unit dose rates from postulated releases to air or to surface water can be calculated for a hypothetical individual and for population groups. Assuming a tritium release of 1 curie per year (Ci/yr) as HTO to the atmosphere, a hypothetical maximum individual residing near a fusion power plant might receive a dose rate of 2 x 10/sup -3/ millirem per year (mrem/yr). Assuming a 1 Ci/yr release to surface waters, this individual might receive a dose rate of 1.5 x 10/sup -5/ mrem/yr. The dose rate to the population of the world including the United Sates and the regional population was estimated to be 1 x 10/sup -2/ man-rem/yr from the release to the atmosphere and 6 x 10/sup -2/ man-rem/yr from the release to surface waters. Dose rates from releases of 1 Ci/yr /sup 14/C to the atmosphere were estimated to be 0.4 mrem/yr to the bone of the hypothetical maximum individual and 2 man-rem/yr to the total body of the world population. Because of the persistence of /sup 14/C in the environment and the fact that carbon is a major constituent of any living thing, efforts should be made to eliminate those releases with available technology such as double containment of the reactors to prevent air leakage.
