The present work determines the contents of active and passive indoor ²²²Rn, ²²⁰Rn, and their daughter in the 32 houses of the Reasi district of J&K, India. The passive ²²²Rn and ²²⁰Rn concentration was measured by dosimeters, whereas the active content was measured by active radon monitor. Progeny sensors and integrated samplers were operated for the evaluation of passive and active daughter contents of ²²²Rn and ²²⁰Rn. The measured averaged values of indoor ²²⁰Rn and ²²²Rn were 73 ± 40 and 22 ± 8 Bqm⁻³, respectively. The radon and thoron equilibrium factor has varied from 0.3 to 1.7 and from 0.006 to 0.6. The fine fraction of the above-mentioned gases was also calculated. The results of Mann–Whitney test statistically demonstrated significant differences between the content of indoor ²²²Rn, ²²⁰Rn, and their daughter for different seasons. The values of ²²²Rn, ²²⁰Rn, and their daughter content were appeared to be elevated in set of mud houses among all sets of houses. The values of all daughter concentration and indoor ²²²Rn were appeared to lie within the limit proposed by various agencies. The total doses were detected less than range commended by ICRP that suggested the district is safe as a health hazard point of view.

目前的工作确定了印度 J&K Reasi 区 32 栋房屋中主动和被动室内²²² Rn、^{220 Rn 及其女儿的内容。}被动²²² Rn 和²²⁰ Rn 浓度由剂量计测量，而活性含量由主动氡气监测仪测量。操作子代传感器和集成采样器来评估²²² Rn 和²²⁰ Rn 的被动和主动子体含量。^室内220Rn和^222Rn的测量平均值分别为73±40和22±8Bqm ^-3。氡气和钍气平衡因子从 0.3 到 1.7 以及从 0.006 到 0.6 变化。还计算了上述气体的细粒部分。^{Mann-Whitney检验结果统计表明，不同季节室内222Rn}、^220Rn及其女儿的含量存在显着差异。^{在所有房屋组中，泥房组中222} Rn、²²⁰ Rn 及其子体含量似乎有所升高。^{所有子浓度和室内222} Rn的值似乎都在各个机构提出的限值内。检测到的总剂量低于 ICRP 推荐的范围，这表明该地区从健康危害的角度来看是安全的。
