The difference between weekly measurements and the annual arithmetic mean of radon indoor concentration CRn,Indoor was studied in the Czech Republic. The deviations were analysed for 1537 weekly measurements which were consecutively obtained in 29 rooms over a period of 1 year and the annual arithmetic mean was calculated for each particular room. The relationship of the deviations to three meteorological parameters (i.e. outside temperature, atmospheric pressure, and weekly rainfall) and to the sequential number of a calendar week was studied. The effect of atmospheric pressure and weekly rainfall was not significant. The deviation between a weekly measurement and the annual arithmetic mean depended significantly on outside weekly average temperatures. If the average outside weekly temperature was below 10 degrees C, the radon concentration was systematically higher than that of the annual arithmetic mean. The deviation variability was lower up to a temperature of 10 degrees C. If the weekly average outdoor temperature was higher than 10 degrees C, the uncertainty of a weekly measurement of radon concentration was also higher.
在捷克共和国，对室内氡浓度CRn,Indoor的每周测量值与年度算术平均值之间的差异进行了研究。分析了在1年时间内于29个房间连续获得的1537次每周测量值的偏差，并计算了每个特定房间的年度算术平均值。研究了这些偏差与三个气象参数（即室外温度、大气压力和每周降雨量）以及日历周序号之间的关系。大气压力和每周降雨量的影响不显著。每周测量值与年度算术平均值之间的偏差显著取决于每周的室外平均温度。如果每周室外平均温度低于10摄氏度，氡浓度系统性地高于年度算术平均值。在温度达到10摄氏度之前，偏差变异性较低。如果每周室外平均温度高于10摄氏度，氡浓度每周测量的不确定性也较高。
