In the present work, we report the results of measurements of indoor ²²²Rn, ²²⁰Rn, and their progeny concentrations in Ghuttu region of Tehri Garhwal district in the Uttarakhand state of India for radiation protection purposes. The measured concentrations of ²²²Rn, ²²⁰Rn, and their progeny were used to estimate the inhalation doses received by the public. The measured values were found to depend upon different seasons of a calendar year. The annual effective dose attributed to ²²²Rn, ²²⁰Rn, and their progeny exposure was estimated in the range of 0.93–2.37 mSv y⁻¹ with an average of 1.54 ± 0.42 mSv y⁻¹. No significant health risk has been found to be associated with the exposure of ²²²Rn, ²²⁰Rn, and their progeny in the study area.

在目前的工作中，我们报告了印度北阿坎德邦 Tehri Garhwal 区 Ghuttu 地区室内²²² Rn、²²⁰ Rn 及其后代浓度的测量结果，用于辐射防护目的。²²² Rn、²²⁰ Rn 及其后代的测量浓度用于估计公众接受的吸入剂量。发现测量值取决于日历年的不同季节。归因于²²² Rn、²²⁰ Rn 及其后代暴露的年有效剂量估计在 0.93–2.37 mSv y ^-1范围内，平均为 1.54 ± 0.42 mSv y ^-1. 没有发现显着的健康风险与研究区域中²²² Rn、²²⁰ Rn 及其后代的暴露有关。
