These high levels are caused by a variety of factors, including fluid dynamics, geological structures, hydrocarbon reserves, geological composition, and human activities associated with gas production. According to the assessment of radiological risk indices, some of them are higher than the advised thresholds. The distribution features of the radioactive concentrations were investigated using statistical techniques, such as descriptive statistics, principal component analysis, and hierarchical cluster analysis.

To safeguard the environment and occupational exposure, appropriate management measures, including regular radiological monitoring, dust control, safe handling of core materials, and worker radiation safety practices, are recommended. Overall, the study emphasizes how crucial it is to understand and monitor the radiological hazards due to gas extraction operations in Bangladesh in order to protect both employees and the local population.</p></div>
