HT and HTO in the environment at Chalk River
The release of tritium into the public environment from heavy water reactor operations at Chalk River Nuclear Laboratories is about 0.1% of the Derived Release Limit which is based on internationally accepted standards. A mean discharge of 500 TBq/a of HTO vapour to the atmosphere has resulted in concentrations in precipitation at the plant boundary of 74 Bq/L. (1 TeraBq = 10/sup 12/Bq = 27 Ci). A dilution factor of 6 x 10/sup 7/ m/sup 3//s is observed. Measurements of HT in tree leaf moisture and integrated snow cores serve to delineate the dispersal plume. Measure discharges of liquid HTO to local surface and groundwaters totaling 147 TBq/a agree reasonably well with amounts observed in the Ottawa River. Preliminary measurements have shown that minor amounts of HT are being released to the atmosphere from the Chalk River facilities.
