The present study involves the measurement of radionuclide contents and radon/thoron exhalation rate in the soil samples collected from the 30 villages of Jammu district, J & K, India. Thallium-doped sodium iodide detector and advanced Smart Rn Duo monitor were used for the measurement of the radionuclide contents and radon/thoron exhalation rates. The radon flux rate was also measured by using a surface chamber technique. The radon mass exhalation rate in the soil samples has been found to vary from 15 ± 0.4 to 38 ± 0.8 mBq kg⁻¹ h⁻¹, while thoron surface exhalation rate has been found to vary from 90 ± 22 to 4880 ± 280 Bq m⁻² h⁻¹. The mean value of radium equivalent activity (99 ± 27 Bq kg⁻¹) has appeared to be well within the admissible limit of 370 Bq kg⁻¹ suggested by the Organization for Economic Cooperation and Development (2009) report. The values of various parameters related to radiological hazards were also calculated, and all parameters have been found to be well below the safe limits given by various organizations. Thze outcomes pointed out that the region was protected from danger as per health risk effects associated with these radionuclide contents are concerned.

本研究涉及从印度J＆K查mu地区30个村庄收集的土壤样品中放射性核素含量和ra / tho气呼出率的测量。掺碘化钠检测器和先进的Smart Rn Duo监测器用于测量放射性核素含量和ra / tho呼出率。using通量率也通过使用表面室技术来测量。已发现土壤样品中mass的呼出速率在15±0.4至38±0.8 mBq kg ^-1 h ^{-1之间变化}，而表面的呼出速率在90±22至4880±280 Bq m之间变化^-2小时^-1。镭当量活度的平均值（99±27 Bq kg ^-1）似乎已完全在经济合作与发展组织（2009）报告建议的370 Bq kg ^-1的容许范围内。还计算了与放射危害有关的各种参数的值，并且发现所有参数均远低于各个组织给出的安全极限。结果表明，根据与这些放射性核素含量相关的健康风险影响，该地区受到保护免受危险。
