In the present study, the contemporary indoor radon activity concentration and the surface-deposited 210Po activity were measured in 65 Romanian dwellings. The activity of trapped 210Po on the glass surface was measured using the (CR-LR) difference technique. The retrospective radon activity concentration estimated on the basis of age-adjusted 210Po activity was found to have a geometric mean of 318 Bq m-3, being higher than the geometric mean (250 Bq m-3) of the contemporary indoor radon measurements, measured with two types of track detectors (RSKS and Radtrak2®). By applying Lin's concordance correlation coefficient, a substantial strength of agreement (rC = 0.94) was obtained between RSKS and Radtrak2® results, respectively a poor agreement (rC = 0.71) between the retrospective and contemporary methods. The ratio between contemporary and retrospective radon concentrations has a geometric mean of 0.8 and range from 0.2 to 3.9.
在本研究中，对罗马尼亚65所住宅内的当代室内氡活度浓度和表面沉积的210钋活度进行了测量。使用（CR-LR）差值技术测量玻璃表面捕获的210钋的活度。基于年龄校正后的210钋活度估算的回顾性氡活度浓度的几何平均值为318 Bq m-3，高于使用两种径迹探测器（RSKS和Radtrak2®）测量的当代室内氡测量值的几何平均值（250 Bq m-3）。通过应用林氏一致性相关系数，RSKS和Radtrak2®结果之间获得了较高的一致性强度（rC = 0.94），回顾性方法与当代方法之间的一致性较差（rC = 0.71）。当代与回顾性氡浓度之比的几何平均值为0.8，范围为0.2至3.9。
