Generalized Approach to Comparative Assessment of the Effect of Radiation from Nuclear Fuel Cycles on Biota

摘要

An approach to evaluating a generalized index of the radiation effect of NFC objects on biota is proposed. The effect of the radiation factor on the collection of representative natural organisms belonging to difference taxonomic groups is taken into account. The change in the proposed index for individual actinides flowing with activity 1 MBq into the environment and their decay products is calculated. The actinides present in spent fuel are considered in the calculations: Am-241,Am-242m,Am-242,Am-243, Cm242-248, Np-237, Pu-238-242,Pu-244, and U-235,U-236,U-238. The index developed is suitable for radioecological assessment of the objects of open and closed fuel cycles. The results of such assessment are an important element of the environmental validation of new nuclear power technologies.
