Independent environmental monitoring and public dose assessment around the Canadian Nuclear Power Plants

Radiological impact to members of the public living around the Canadian Nuclear Power Plants (NPPs) was assessed using environmental monitoring data for tritium, gross alpha, 137 Cs and 131 I and dose calculations. The monitoring data exhibited concentrations much lower than guidelines and are comparable to other results in Canada. Tritium is the most significant radionuclide and major contributor to the very low dose (µSv y −1 ), to members of the public. The tritium dose was a fraction of the regulatory dose limit and background radiation dose. The public living around Canadian NPPs is not exposed to radiation that would result in a radiological impact.
