The survey on indoor radon exposure was undertaken to explain whether the excess in lung cancer deaths in Cracow city center may be attributed to this particular exposure. A total of 310 detectors was placed in households randomly chosen from three homogenous strata of residential buildings. The first stratum included house in the old city center constructed predominantly out of the stone bricks. The second stratum covered area of the city with big apartment condominiums built out of concrete blocks. The third stratum consisted of single family houses located in a suburban area. From each of these residency strata a random sample of equal number of households has been chosen and the radon detectors were placed in households located at different levels of buildings. The three-month radon sampling data were used to determine the distribution of various levels of radon in the households. In the measurement of radon exposure the Landauer alpha-track samplers were used. The data collected show that the best single predictor of indoor radon concentrations was type of building. Other variables found to be associated significantly with indoor concentrations were household level in the building and house age. In general, residences with a concrete slabs and dwellings with rarely-opened windows were found to have slightly higher radon concentrations.
开展了一项关于室内氡暴露的调查，以解释克拉科夫市中心肺癌死亡人数过多是否可能归因于这种特定的暴露。从住宅建筑的三个同质层次中随机选择的家庭中共放置了310个探测器。第一层包括主要由石砖建造的老城区中心的房屋。第二层覆盖了城市中由混凝土砌块建造的大型公寓共管区。第三层由位于郊区的独栋房屋组成。从这些居住层次中的每一层中随机选择了数量相等的家庭样本，并将氡探测器放置在建筑物不同楼层的家庭中。三个月的氡采样数据用于确定家庭中不同水平氡的分布。在氡暴露测量中使用了兰道尔α径迹采样器。收集到的数据表明，建筑物类型是室内氡浓度的最佳单一预测指标。发现与室内浓度显著相关的其他变量是建筑物中的家庭楼层和房屋年龄。一般来说，有混凝土板的住宅和窗户很少打开的住宅的氡浓度略高。
