"Following the Chernobyl nuclear reactor accident in April 1986, the National Water Research Institute initiated measurements on samples obtained as part of our Acid and Toxic Rain projects designed to study the impact of the accident on Canadian freshwater systems. The results obtained so far show that the radionuclide deposition in Canada was several thousand times lower in Canada than in Western Europe. Specific measurements failed to detectany Chrenobyl radionuclides in Lake Ontario, even when, highly sensitive NWRI techniques were used. Presumably, the diluation effect pushed the levels below our detection capabilities. It is unlikely that any Chernobyl-derived radionuclides reached populations deriving drinking water from water filtration plants. Also, unlike in Europe, the Chernobyl radioactivity will not leave a 'marker' in the Canadian aquatic environment"--Management perspective.
