简介
Soil samples were collected from different localities of districts Jhelum, Chakwal, Rawalpindi and Attock, Punjab Province, Pakistan with an aim to measure naturally occurring radionuclides, namely 226 Ra, 232 Th, 40 K and fallout 137 Cs radionuclide using a P-type coaxial high purity germanium (HPGe) γ-ray spectrometer. Measured specific activities of 226 Ra, 232 Th and 40 K in these soil samples ranged from 26.02 ± 7.11 to 93.54 ± 8.13 Bq kg −1 , 29.34 ± 2.58 to 114.41 ± 2.80 Bq kg −1 and 348.15 ± 3.20 to 752.98 ± 4.20 Bq kg −1 , respectively. Activity due to 137 Cs was observed in some locations which ranged from 0.4 ± 0.2 to 7.8 ± 0.3 Bq kg −1 . From the measured activity concentrations, radium equivalent activity concentrations …
