pi 11 Answer Yes thenuclides ean be broken down by name. As previously stated there are approximately 200 radionuclides created in the fisstoning process “but it is possible to estimate the radiation doses to the population pri marily by considering 5 significant radionuclides that may be deposited in.ternally. The latest values for the dose commitments for populations in the North Temperate Zone from nuclear tests carried out before 1968 are given in the following Table taken from a recent report of the United Nations Tare 1.
