A total of 21 soil samples and 17 water samples were collected from various locations. A high-purity germanium gamma detector HPGe was used to measure the concentrations of ⁴⁰K, ²³²Th, and ²²⁶Ra in all samples, along with the concentrations of heavy metals. In soil samples, the average concentrations of ⁴⁰K, ²³²Th, and ²²⁶Ra were 731.5, 30.7, and 28.16 Bq kg⁻¹, respectively. While some samples showed higher than permissible levels for ²²⁶Ra and ²³²Th, the overall average remained within acceptable limits.

In water samples, the average concentrations of these nuclides were 5.38, 0.73, and 0.66 Bq L⁻¹, all within the global safety limits. Radiological risk assessments for soil indicated an average radium equivalent activity (Ra_eq) of 124.4 Bq kg⁻¹, absorbed dose rate in air of 59.9 nGy h⁻¹, annual effective dose rate of 0.07 mSv y⁻¹, outdoor excess lifetime cancer risk (ELCR) of 0.26 × 10⁻³, and annual gonad equivalent dose (AGED) of 336.6 mSv y⁻¹.
