Abstract

The purpose of this study is to investigate the Anthropogenic and Naturally Occurring Radionuclides in Soil Samples of Kurigram District in Bangladesh.  The level of radioactivity in collected soil samples was determined by means of a gamma-ray spectrometry. The observed radioactivity of 238U, for all samples varies from 13±3 to 70±6 Bqkg-1, 232Th ranges from 17±4 to 182±8 Bqkg-1 and 40K ranges from 44±22 to 895±43 Bqkg-1. The radioactivities of 238U, 232Th and 40K were compared with the reported values of other locations of Bangladesh and other parts of the world. Raeq ranges from 117 to 178 Bqkg-1. The estimated Absorbed Dose Rate based on soil radioactivity ranges from 54 to 82 n Gyh-1. Hex varies from 0.32 to 0.48 m Svy-1. The outcomes of this study show that the Hex values from all soil samples are below the permissible limit which is recommended by International Commission of Radiological Protection (ICRP) 60. The Deff from outdoor was estimated in this study varies from 66 to 101 µSvy-1 with average value of 83 µ Svy-1, which is slightly larger than the effective dose of 70 µSvy-1. The radioactivity of natural occurring radionuclides in soil samples of Kurigram poses no threat to general public there. Artificial radionuclide 137Cs was not found in this studied.
