Radiological Monitoring Activities in the Northwest Territories, Canada

Results from the radiological monitoring activities relating to surface water and old uranium mining waste sites in the Northwest Territories are described. Data from the Baker Lake site reveal that the radionuclide levels in the surface water are quite low. In view of limited monitoring data, three new stations have been established in the Northwest Territories. Initiation of a similar program for the Yukon is recommended. Studies carried out at uranium mining waste sites by government agencies and private consultants concluded that the present levels of radionuclides in the associated waters were posing no health hazards.
