title: Early Canadian results on the long-range transport of Chernobyl radioactivity.
abstract: The levels of Chernobyl-derived radionuclides were measured in several rain, snow and water filtration plant floc samples collected from various locations in Canada. The data indicate that the Chernobyl release had negligible effect on the radiological quality of Lake Ontario waters. The detection of some activation products in pre-Chernobyl samples, presumably arising from the accidental release of radioactivity during weapon testing at the Nevada site, is also reported. Some data from the ongoing measurements on rain samples are presented to discuss the possible use of Chernobyl radionuclides for delineating tropospheric transport processes. Fractionation factors for the major radionuclides are also reported.
