In this study, the natural radionuclides in soil and sand have been measured by using high purity germanium (HPGe) detector. While, radon exhalation rate has been measured by Alpha GUARD. The data analysis is performed to determine ²²⁶Ra, ²³²Th, and ⁴⁰K activity concentrations in addition to ²²²Rn exhalation rate. The values of radium equivalent activity (R_aeq), external hazard index (H_ex), internal hazard index (H_in), and absorbed dose rate were ranged from 46.46 to 124.16 Bq⋅kg⁻¹, 0.07 to 0.33 Bq⋅kg⁻¹, 0.09 to 0.42 Bq⋅kg⁻¹, and 13.24 to 58.37 nGy⋅h⁻¹ respectively in all samples. The area and mass exhalation rates were increased from 9.16 ± 2.83 to 16.18 ± 2.83 Bq⋅m⁻²⋅h⁻¹ and 1.8 ± 1.34 to 11.35 ± 0.98 Bq⋅kg⁻¹⋅h⁻¹ respectively.
