[Correlation between the probability and dosage characteristics of safety in the processing of radioactive liquids].

The authors show it possible and expedient to use the probability characteristics for evaluation of the safe operation of radiation-dangerous plants. The calculated values of doses that might be following an accident at these plants fail to give an adequate account of reality since the doses are largely variates. To divide accidents into classes or levels, it is necessary to use the principle of non-excess of accident probability of the given class or level rather than the threshold principle of non-excess of doses.
