Abstract

The seasonal variations of the indoor radon activity concentrations were determined in the 97 dwellings of Trabzon, Turkey. The annual average indoor radon activity concentration varied from 8 to 583 Bq/m3. The average winter/summer ratio of radon activity concentrations was 3.62. The gamma activity concentrations in the soil samples were determined as 41, 38, 443 and 25 Bq/kg for 226Ra, 232Th, 40K and 137Cs, respectively. The average gamma dose rate in air and the annual effective dose equivalent for outdoor occupancy were calculated as 63 nGy/h and 77 μSv/y, respectively.

► This study sheds light on the indoor radon activities in dwellings and radionuclides in oil samples. ► Indoor radon activities were investigated according to the seasonal variation and the floor number. ► Average gamma dose rate in air and the annual effective dose equivalent were calculated. ► Results will be valuable database for future estimations of the impact of radioactive pollution.
