Abstract
The collective dose is examined as an integral characteristic of the radiological effect of nuclear fuel cycle enterprises on the general population. A relation is obtained for evaluating the ecological factor, which takes account of the specifics of radionuclides from the standpoint of their migration capacity and the particularities of dose load formation. The ecological factors are calculated for 241Am, 242mAm, 242Am, 243Am, 242Cm, 243Cm, 244Cm, 245Cm, 246Cm, 247Cm, 248Cm, 237Np, 238Pu, 239Pu, 240Pu, 241Pu, 242Pu, 244Pu, 235U, 236U, and 238U. Links where the activity of the daughter radionuclides was taken as equal to the activity of long-lived precursors are singled out in the decay chains of the actinides. The dynamics of the yearly collective dose for the general population, formed by individual actinides with activity 1 Bq in the emissions and their decay products, for a long period of time is calculated. The results are suitable for performing comparative radioecological assessments of enterprises in open and closed nuclear fuel cycles.
