Features of Monitoring the Radioactive Situation in the Surface Air Layer and Precipitation near a Nuclear Power Plant

Abstract

Abstract The influence of nuclear power plants on the population and agricultural fields located within a radius of 150 km from the nuclear power plant is considered. The features of monitoring the radioactive situation in the surface layer of the air have been studied. The volumetric activity of 137Cs near the nuclear power plant has been estimated. A sufficiently accurate way of placing monitoring installations has been determined (taking into account the direction of the winds, the distance to the nuclear power plant, and nearby settlements). It has been established that some radionuclides, which are currently poorly controlled, require additional measurements. A variant of replacing cuvettes with sides with universal collection tanks is proposed to provide more precise control. The placement of monitoring installations fully complies with the IAEA recommendations.
