"November 2015." The copy has been replaced as requested by the author-department (Jan. 5, 2017). Includes bibliographical references. This Special Environmental Radioactivity in Canada Report provides a comprehensive account of the environmental radiation surveillance activities conducted by Health Canada in the months immediately following the Fukushima accident which includes an assessment of the overall levels of radiation and its impacts to Canada. Working in conjunction with Environment Canada, the levels of airborne contaminants and deposition were calculated for North America using their state of the art contaminant dispersion models. During this process, agreement was established between actual airborne contaminant measurements, both from the IMS and domestic network measurements, and the modelled values. Hence, the models provided reliable estimates of the airborne concentrations and ground deposition of contaminants from the Fukushima accident across Canada, even where no sampling equipment existed. Finally, the overall impact of these contaminants to the Canadian environment was assessed and determined to be of no health concern to Canadians. Using a conservative approach, the maximum dose to an individual resulting from the Fukushima accident was estimated to be less than 0.0003 (1/ 3,000) of the typical annual dose of an individual living in Canada from the natural background radiation. This additional dose resulting from the Fukushima accident is far less than the normal variation in dose due to background radiation across Canada. There are no health impacts related to this incremental dose. gccst Nuclear power plants gccst Accidents gccst Radiation gccst Radioactive materials gccst Measurement Canada. Health Canada. Canada.
