Statistical characteristics of the collective dose

A statistical approach for estimating the yearly effective collective dose is proposed. The distribution law for the collective dose is proposed on th e basis of the assumption that the distributions of the number of people in the controlled group and the individual irradiation dose are random. It is shown that the distribution law for the collective dose has a quasiexponen tial form and is characterized by an average value and a variance. It is sh own for a statistical analysis of the multiyear data from individual dosime tric monitoring of workers at the Moscow Scientific and Industrial Associat ion Radon that the hypothesis advanced is consistent with observations. Pra ctical recommendations are given for calculating collective dose statistics . 3 figures, 8 references.
