Abstract:

Radiometric analysis of soil samples, collected from northern alluvial sediment plains between rivers Ravi and Chenab, has been carried out. Activity concentrations of 226Ra, 232Th, 40K and the artificial radionuclide 137Cs were estimated by using high-purity germanium detector. Subsequent values of activity concentrations were used to find terrestrial absorbed dose rate and annual effective doses received by resident of area. The mean radioactivity levels of 226Ra, 232Th, 40K and 137Cs were found to be 45.0 ± 1.3, 59.6 ± 2.8, 613.8 ± 20.0 and 4.0 ± 0.2 Bq kg−1, respectively. Terrestrial absorbed dose rate and annual effective dose received by public were found to be 85.1 nGy h−1 and 0.5 mSv, respectively. The activity concentrations of 226Ra, 232Th, 40K and 137Cs and resulting doses obtained for the current study were compared with data available in the literature and with international standards.
