Because to extensive utilization of soil as a building/construction stuff, the activities of ²³⁸U, ⁴⁰K, ²³²Th, and exhalation studies in solid samples have been measured using thallium activated sodium iodide (NaI(Tl)) gamma detector and scintillation-based smart RnDuo monitor. The measured activity concentration of radionuclides lies in the range of 2.76–38.96, 12.47–65.70, and 199–450 Bq/kg for uranium (C_U), thorium (C_Th), and potassium (C_K), respectively. The annual effective dose rate due to radionuclides is within the secure limit suggested by ICRP. The radium equivalent activity of all the samples is under 100 Bq/kg. The maximum outward and inside risk indices of all these samples are below the values of 0.37 and 0.43. No direct correlation has been seen between ²³⁸U and its mass exhalation rate as well as ²³²Th and its surface exhalation rate in soil samples.
