Cumulative fission yield

WebThis report contains tables for individual and cumulative fission yields together with half-lives for occuring, significant isobars. Prediction of the most probable radionuclide composition in the case of a real nuclear weapons explosion is of course not quite feasible. Therefore, for exercise purposes one have to choose a Webfission, νd, can be calculated by integrating over all time for a single fission. Thus: νdnii i ni i i ==∑∑PR Pc The total decays of nuclide i per fission, R i, is equal to the cumulative fission product yield of i. Thus, for a pure sample of an actinide, if the cumulative yields, c i are known the νd can be calculated.
