In this study, seasonal observations of radon concentration changes inside buildings carried out in the northeastern region of Poland is presented. One-year measurements of radon concentrations were performed in chosen buildings. The integral method of Cr-39 trace detectors in diffusive chambers was used. Mean values of radon concentrations were determined in monthly, 2-, 3-, 6-month, and annual observations. The fraction of a mean annual concentration of the value obtained in a shorter observation was calculated. Monthly concentration values were from about 0.2 to 14.9 of the annual mean. All buildings revealed seasonal fluctuation of radon concentration. Negative correlation of indoor radon concentration in the buildings and the mean temperature outside was observed in most examined buildings. The lowest coefficient range, determining which part of the annual mean value would be obtained in the 6-month observation, was gained for exposure begun in April or October.
本研究展示了在波兰东北部地区对建筑物内氡浓度变化进行的季节性观测。在选定的建筑物中进行了为期一年的氡浓度测量。采用了扩散室内Cr - 39微量探测器的积分法。在每月、2个月、3个月、6个月和年度观测中确定了氡浓度的平均值。计算了在较短观测中获得的值占年平均浓度的比例。每月浓度值约为年平均值的0.2至14.9倍。所有建筑物都显示出氡浓度的季节性波动。在大多数被检查的建筑物中，观察到建筑物内室内氡浓度与室外平均温度呈负相关。对于4月或10月开始的暴露，在6个月观测中获得的决定年平均值哪一部分的最低系数范围。
