Abstract |
|
|
| Human body exposed natural radiation by inhalation, ingestion or absorption. Excess exposure of ionizing radiation to human can cause harmful effects. Water is a source of exposed radiation to human body. In Bangladesh only a limited number of studies on internal dose assessment due to water have been performed. The main purpose of this present study is to calculate activity concentrations of natural radionuclides [238U (226Ra), 232Th, and 40K] and gross Alpha and gross Beta activity of water from different upazila of Satkhira district, Bangladesh. To measure the natural radioactivity concentration a high resolution Gamma-ray spectroscopy with an HPGe detector in a low background configuration and a Zinc Sulphide Scintillation Detector Zn(Ag)S has been carried out the analysis of gross Alpha and gross Beta activity . The findings of Gross-Alpha and Gross Beta activity mostly similar with the findings of previous studies of different countries. Some cases natural radiation dose slightly excided the previous studies of different countries. Considering this data as a baseline data further a broad line study may be happened and can be used in future to evaluate any changes due to any vulnerability. |
