The natural radioactivity and background content of anthropogenic radionuclides in groundwater near the Leningrad NPP was studied based on the results of monitoring observations. Radiation characteristics of the Quaternary, Lomonosov, and Vendian aquifer complexes were analyzed. The total alpha (α)- and beta (β) activities, as well as the content of radon (222Rn), radium (224Ra, 226Ra, 228Ra), polonium (210Po), lead (210Pb), thorium (232Th), potassium (40K), and uranium (238U, 234U) were measured. The increased activity of natural radionuclides in the the Vendian aquifer was noted. A typical level of natural radioactivity was estimated for the groundwater in the study area. The total alpha (α)- and beta (β) activities, the content of cesium (137Cs), strontium (90Sr), tritium (3H) were measured among the anthropogenic radionuclides. The background levels of anthropogenic radionuclides in groundwater in the study area were measured and provided.
