The Natural Radionuclides in Soils of Subotica (Serbia): Distribution and Corresponding Gamma Dose Rates
MetadataShow full item record
The activity concentrations of K-40, Ra-226 and Th-232 from 50 locations on the territory of Subotica, North Serbia, were determined by gamma ray spectrometry. Based on the activity concentrations of investigated radionuclides, the absorbed gamma dose rate in the air was calculated. The mean values of activity concentrations were found to be 290 Bq/kg for K-40, 20 Bq/kg for Ra-226 and 18 Bq/kg for Th-232. The total absorbed gamma dose rate varied between 24 and 46 nGy/h. The mean value of 32 nGy/h was lower than the world average value.
