The natural radionuclides activity concentration of 232Th, 40K and 226Ra were measured in soils around the thermal power station in Udupi using NaI(Tl) gamma ray spectrometer. 232Th, 40K and 226Ra mean activity in soils were found to be 17.72 Bq/kg, 54.23 Bq/kg and 32.82 Bq/kg respectively. The soil is commonly used construction material in the region. Soil is used to make bricks to construct houses and dwellings. In view of this, the radiological hazard due to natural radioactivity in soil such as Radium equivalent activity, Absorbed gamma dose rate (D), Internal hazard index (Hin), External hazard index (Hex)were assessed.

Radioactivity, soil, coal-based power plant, Internal hazard index (Hin), External hazard index (Hex).
