Abstract

There are given results of radioactivity research in soil samples within the territory of some regions of the Black Sea coast. Ten samples have been collected from 10 locations. Up to 22 radionuclides were identified. Activity concentration of radionuclides of Th-232 family was in limits from 15.2 to 32.5Bq/kg (mean, 24.5Bq/kg), U-238 family – from 9.7 to 23.8 Bq/kg (mean, 17.2Bq/kg), U-235 family - from 0.62 to 1.31Bq/kg (mean, 0.93Bq/kg). Also individual radionuclides have been identified: K-40 – from 81.1 to 485Bq/kg (mean, 300Bq/kg), Cs-137 – from 8.8 to 191 Bq/kg (mean, 68.4Bq/kg); Be-7 – from 2.2 to 29.5 Bq/kg (mean, 12.3 Bq/kg). Radium equivalent activity varied from 44.9 to 89.4Bq/kg (mean, 73.2Bq/kg). Annual effective dose varied from 0.027 to 0.054mSv/y (mean, 0.043 mSv/y).
