In view of the dispersible nature of the radiologically significant gaseous radon (²²²Rn) and its dependence on metrological variables, an investigation was carried out in the uranium mineralized region of Jaduguda. Two distinct locations, comprising of prototype dwellings and outdoor environment outside the dwellings were chosen for the comparative study. The investigation was carried out during monsoon, autumn and winter seasons so that a profile ranging from minima to maxima can be accounted. Along with the ²²²Rn concentration profile and gamma level, the metrological variables such as ambient temperature, pressure, relative humidity has also been investigated. Results of sixty six (66) outdoor and thirty nine (39) dwellings monitoring was found to have ²²²Rn concentration ranged from 9 to 68 Bq m⁻³ and 35 to 130 Bq m⁻³, respectively, in outdoor and indoor with corresponding average value of ²²²Rn concentration were found 34 ± 13 and 79 ± 24 Bq m⁻³, respectively. These values are well within the expected range of a uranium mineralized area. Also, the outdoor ²²²Rn activity concentration is about 43% of the indoor ²²²Rn activity concentration, which can be attributed to greater atmospheric dilution and related metrological variables like higher temperature.

鉴于具有放射性意义的气态氡气（²²² Rn）的分散性及其对计量变量的依赖性，在贾杜古达铀矿化地区进行了调查。选择两个不同的地点进行比较研究，包括原型住宅和住宅外的室外环境。该调查是在季风、秋季和冬季进行的，以便可以计算出从最小值到最大值的剖面。除了²²² Rn 浓度分布和伽玛水平外，还研究了环境温度、压力、相对湿度等计量变量。六十六（66）个室外和三十九（39）个住宅的监测结果发现，室外和室内的²²² Rn 浓度分别为 9 至 68 Bq m ^-3和 35 至 130 Bq m ^-3，具有相应的平均值发现²²² Rn浓度值分别为34±13和79±24Bq m ^-3。这些值完全在铀矿化区域的预期范围内。此外，室外²²² Rn 活性浓度约为室内²²² Rn 活性浓度的 43%，这可归因于更大的大气稀释度和相关计量变量（例如更高的温度）。
