This table is from the final environmental impact statement for the Chalk River Mound (aka the “NSDF”), published in early December 2020
Note that the table includes five isotopes of plutonium.
Note also that Twenty-five out of the 30 radionuclides listed are long-lived, with half-lives ranging from four centuries to more than four billion years. Materials such as these are not supposed to be disposed of in above-ground landfills according to the International Atomic Energy Agency.
