The Rooppur Nuclear Power Plant (RNPP), the first nuclear power plant in Bangladesh with a capacity of2.4 GWe, is under construction on the bank of the river Padma, at Rooppur in Bangladesh. Measurementof background radioactivity in the natural environment adjacent to RNPP finds great importance forfuture perspectives. Soil and sediment samples collected from upstream and downstream positions ofthe Padma River (adjacent to RNPP) were collected and analyzed by HPGe gamma-ray spectrometry forprimordial radionuclides. The average activity concentrations (in Bqkg 1) of 226Ra, 232Th and 40K radionuclides in soil samples were found to be 44.99 ± 3.89, 66.28 ± 6.55 and 553 ± 82.17 respectively. Respective values in sediment samples were found to be 44.59 ± 4.58, 67.64 ± 7.93, 782 ± 108. Relevantradiation hazard indices and dosimetric parameters were calculated and compared with the worldaverage data recommended by US-EPA. Analytical results show non-negligible radiation hazards to thesurrounding populace. Measured data will be useful to monitor any change of background radioactivityin the surrounding environment of RNPP following its operation for the generation of nuclear energ
