Measurement of radioactive impact of the gas well accident on environment of Sylhet division in Bangladesh

The main goal of this study is to carry out the public exposure contribution from radioactive materials occurring due to the accident of natural gas exploration well of Sylhet division in Bangladesh. This study has been performed by using a gamma spectrometry of Genie 2000 software embedded PC-based High Purity Germanium (HPGe) detector system. The measured activity concentrations of naturally occurring radionuclides 232Th, 226Ra, and 40K have been in the public safety limit on the environment of the study areas. The specific activity of detected anthropogenic radionuclide 137Cs has been found to be very little with a mean value of 1.65 ± 0.61 and 1.13 ± 0.57 Bq•kg–1 in the Magurchhera and Haripur gas field area respectively.
