Natural and anthropogenic radioactivity of the environment is of particular interest for ecological researches. The purpose of this work is to characterize radioactivity in the soil of the Black Sea coastal strip in Ureki-Shekvetili zone (Georgia). Measurements were carried out using gamma-spectrometry method. There were identified up to 21 radionuclides in samples of coastal and bottom soil. Mean activity concentration of radionuclides of family Th-232 changed from 4.1 up to 16.3 Bq/kg, family U-238 - from 2.9 up to 17.5 Bq/kg, family U-235 - from 0.2 up to 3.3 Bq/kg. The greatest activity concentration was observed for K-40 (maximal value was 1127 Bq/kg in bottom soil samples). Activity of anthropogenic radionuclide Cs-137 in the samples of coastal soil varied more than by 2 orders - from 1.7 up to 262 Bq/kg; Cs-137 concentration in bottom soil samples is appreciably less than in coastal soil; activity of anthropogenic radionuclide Cs-134 identified in some cases was 0.12 Bq/kg.
