As part of a retrospective epidemiologic study of lung cancer in women, alpha-track and charcoal canister radon measurements were made in a sample of New Jersey residences. The alpha-track measurements were designed to yield estimates of annual average exposures of dwelling occupants, while charcoal canister measurements were designed to yield "worst case" concentrations for screening purposes. The year-long living area and basement screening measurements had geometric means of 19 Bq m-3 (0.52 pCi L-1) and 56 Bq m-3 (1.5 pCi L-1), respectively. Measurements of radon gas with different detectors and on different floors were compared to each other within residences. Ratios of screening to annual average results became more extreme as the measured concentrations increased; the mean ratio of basement canisters to year-long living area alpha-track detectors was 5.6 vs. 2.7 for houses that screened above and below 150 Bq m-3 (4 pCi L-1), respectively. Although the residence sample from which these data were drawn is not necessarily representative of either state or national housing stock, these observations, if verified, may have important implications for procedures and decision strategies designed to reduce individual and population exposures to radon.
作为一项针对女性肺癌的回顾性流行病学研究的一部分，在新泽西州的一些住宅样本中进行了α径迹和活性炭罐氡测量。α径迹测量旨在得出居住者年平均暴露量的估计值，而活性炭罐测量旨在得出用于筛查目的的“最坏情况”浓度。为期一年的居住区域和地下室筛查测量的几何平均值分别为19 Bq m-3（0.52 pCi L-1）和56 Bq m-3（1.5 pCi L-1）。在住宅内，对不同探测器在不同楼层进行的氡气测量结果进行了相互比较。随着测量浓度的增加，筛查结果与年平均结果的比值变得更加极端；对于筛查结果高于和低于150 Bq m-3（4 pCi L-1）的房屋，地下室活性炭罐与居住区域年平均α径迹探测器的平均比值分别为5.6和2.7。尽管这些数据所取自的住宅样本不一定能代表该州或全国的住房存量，但这些观察结果若得到证实，可能会对旨在减少个人和人群氡暴露的程序和决策策略产生重要影响。
