Garin Y. Development of method of identification and quantitative estimation of ALARA limit of an effective doze in the radiation monitoring regulation of NPP's personell

The analytical results defining range of temperatures and quantitative estimation of critical doze at which in biosubstance the radiation-induced phase transition of the first kind is observed, and also quantitative evaluation of macroscopic time scale of relaxation of biophysical system to initial state for the first time are obtained. The determination of relative biological efficiency for the first time is given and the quantitative expression for criterion of ionizing radiation quality in the area of low dozes is obtained. Criterion of biophysical identification of value of limit of an effective doze which indicates low bound of ALARA principle action is grounded. The task of completeness and sufficiency of NPP's personnel radiation monitoring and base task of "cost-benefit" analysis in frameworks of risk-oriented approach are mathematically formulated.
