Abstract |
|
|
| For this study, surface water was collected from Atomic Energy Research Establishment (AERE) (50 samples), Barapukuria Coal Mine (BCM) (50 samples), and Rooppur Nuclear Power Plant (RNPP) construction site area (44 samples) from individual sampling points. Sample collected, prepared, and measured radiation concentration (gross alpha and beta) in the year 2023. All samples were prepared by following the guidelines of EPA 900 and measured in the screening method with a ZnS scintillation counter. For the sample of AERE, the mean activity of gross alpha was 0.0071±0.0008 BqL-1 and the average activity of gross beta was 0.1228±0.0204 BqL-1. For the sample of BCM, the average gross alpha activity was 0.0056±0.0008 BqL-1 and the average gross beta activity was 0.1000±0.0206 BqL-1. For the sample of RNPP, mean gross alpha activity was 0.0031±0.0007 BqL-1 and mean gross beta activity was 0.1356±0.0207 BqL-1. The average annual effective dose (AED) for the samples of AERE was 0.034 mSvy-1, for samples of BCMCL was 0.0276 mSvy-1, and for the samples of RNPP construction site was 0.0363 mSvy-1. All the measured AED values were less than the WHO reference value, which is 0.1 mSv-1. |
