Radionuclide Releases - Nuclear Power Plants / Stack Emissions

This dataset contains the total annual releases of radionuclides released directly to the environment through stack emissions of the nuclear power plants in Canada.

This original radionuclide releases dataset of the nuclear power plants provides results for both stack emissions and direct discharge (i.e. releases to water). The dataset has been divided in two subsets for better discoverability. In this record as its title indicates, you will find the stack emissions results mapped. Make sure to look at the nuclear power plants direct discharge record in order to obtain a complete picture.
