Continuous indoor radon measurements were carried out in two traditional Russian rural houses located in different villages of the Moscow region in summer of 2017 and 2018. In additional, in the summer of 2017, continuous measurements of soil gas radon activity concentration at depth 0.8 m and radon exhalation rate from the ground surface near the house were performed simultaneously. It was found that the indoor radon concentration in rural houses is subject to strong daily variations, which are characterized by highs at night and lows during the day. Indoor radon concentration is directly proportional to indoor and outdoor temperature difference and inversely proportional to wind speed. While the radon exhalation rate from the ground surface, as well as the ventilation of premises (opening doors and windows) practically do not affect the concentration of radon in Russian rural wooden houses.
2017 年和 2018 年夏季，在莫斯科地区的两个不同村庄的两座传统俄罗斯乡村住宅中进行了连续的室内氡测量。此外，在 2017 年夏季，还同时对 0.8 m 深处的土壤气体氡活度浓度和房屋附近地面的氡释放率进行了连续测量。结果发现，乡村住宅内的氡浓度存在强烈的日变化，其特点是夜间高、白天低。室内氡浓度与室内外温差成正比，与风速成反比。而地面的氡释放率以及房屋的通风（开门窗）实际上并不影响俄罗斯乡村木屋中氡的浓度。
