[Radiation safety at atomic electric power stations].

The paper discusses measures to be taken during hypothetic utmost breakdown at nuclear power stations when the amount of radioactive nuclides injected in the atmosphere exceeds the permissible level. Three consecutive steps of the breakdown are distinguished and, correspondingly, medical and hygienic measures are developed to provide radioprotection of the personnel, population, and workers involved in the elimination of the consequences of the breakdown.
