This pioneering study marks the first assessment of radioactivity in soil neighboring the Bhola 225 MW Combined Cycle Power Plant (CCPP) in Bangladesh, which utilizes natural gas and high-speed diesel (HSD). Twenty soil samples collected from the Bhola CCPP revealed average activity concentrations of 226Ra at 33 ± 3 Bq/kg (range: 27 to 65 Bq/kg), 232Th at 46 ± 4 Bq/kg (range: 39 to 54 Bq/kg), and 40K at 539 ± 48 Bq/kg (range: 470 to 630 Bq/kg). The elevated levels of 232Th and 40K are likely due to a combination of the presence of natural minerals, granitic parent rocks, combustion residues, and other environmental factors. While the radium equivalent activity and some hazard indices are within recommended limits, several radiological parameters exceeded established safety thresholds. These findings highlight the need for further investigation such as, site-specific studies to identify sources and spatial distribution of the elevated radioactivity levels, along with long-term monitoring of radiation changes. Proper guidelines should be implemented regarding the use of this soil for agricultural or construction purposes, and local communities should be educated on radiation risks.
