Abstract
Activities of 137 Cs, resulting from globally distributed atmospheric fallout, and natural activities of 226 Ra and 40 K were determined for nine species of fish from five lakes in the Northwest Territories, Manitoba, Saskatchewan and northwestern Ontario. Sample sizes of approximately 25 fish were obtained for each species and location. Selected subsamples were also analyzed for the stable elements Ca, Zn, Cu and K. Surface water samples were collected and activities of 137 Cs and 226 Ra were determined in both dissolved and particulate fractions.
