The article presents the results of radon research, carried out in the area of the mining commune in the Upper Silesian Coal Basin (USCB), Poland. Past investigations in the 1990s on radon concentrations in buildings, located within the mining area, showed that the indoor radon concentrations measured in the area affected by mining were higher than in buildings located outside that area. Currently, all underground hard coal mines within the boundaries of the observed commune have been closed. In 2020, after the closure of the last active mine, radon measurements were started again. The current results of indoor radon concentrations were compared with the archival results from the 1990s. It was found that the radon concentration increased significantly in the basements of buildings where measurements were made in 1990, 2020, and 2021: the maximum values were 260 Bq/m, 644 Bq/m, and 1041 Bq/m, respectively. Therefore, these questions were posed: Do the mine closure processes increase radon migration? How long is the period of the occurrence of changes in radon concentrations in buildings after the cessation of mining operations?
本文呈现了在波兰上西里西亚煤田（USCB）矿区进行的氡研究结果。20 世纪 90 年代对矿区内建筑物氡浓度的过往调查表明，受采矿影响地区测量到的室内氡浓度高于矿区外建筑物的浓度。目前，观察区内所有地下硬煤矿都已关闭。2020 年，最后一个活跃的矿山关闭后，再次开始进行氡测量。当前的室内氡浓度结果与 20 世纪 90 年代的档案结果进行了比较。结果发现，在 1990 年、2020 年和 2021 年进行测量的建筑物地下室中，氡浓度显著增加：最大值分别为 260 Bq/m、644 Bq/m 和 1041 Bq/m。因此，提出了以下问题：矿山关闭过程是否会增加氡迁移？在停止采矿作业后，建筑物中氡浓度变化的发生期有多长？
