Abstract
WWR-M nuclear research reactor (NRR) of the Institute for Nuclear Research (INR) of the National Academy of Sciences of Ukraine was an experimental base for scientific research. During the entire period of operation of the reactor the regular radiation monitoring is carried out on the territory of the sanitary protection zone (SPZ) and the observation zone. In this article, the authors studied several indicators of the radiation monitoring system of the natural environment in the SPZ of NRR namely the level of beta-activity for 2014–2023. It was established that the indicators of the concentration of beta-active aerosols in the air during the last ten years did not show significant fluctuations, which indicates that during the entire period of observation, no increase in the content of radioactive substances was detected in the control objects of the natural environment. But during the study of the average annual values of the density of beta-active radionuclides with settling dust and precipitation at control points in the SPZ in the specified period, the maximum values of this parameter were observed in 2014–2015, which may be a consequence of the fires in the Chornobyl zone. A comprehensive database has been created to develop science-based approaches to optimize the location of stationary control points taking into account changes in the stages of the nuclear installation operation cycle and natural conditions, and to systematize radiation monitoring data.
