The effect of uranium mine tailings on radionuclide concentrations in Langley Bay, Saskatchewan, Canada

From 1955 to 1964 the Gunnar Uranium Mine (Canada) produced approximately 8×103 tonnes of uranium oxide and about 5×106 tonnes of waste rock tailings. Large quantities of fine tailings material washed into Langley Bay, a shallow bay opening onto Lake Athabasca. The limnoiogical characteristics of this bay make it an ideal site to study the movement and impact of some radionuclides in and on the northern environment. This paper describes the physical, chemical, and biological characteristics of Langley Bay and introduces a study of radionuclide movement begun in 1983.
