使用高灵敏度便携式探测器测量塞浦路斯室内氡（Rn-222）浓度
Indoor radon (Rn-222) concentration measurements in Cyprus using high-sensitivity portable detectors
摘要：
使用高灵敏度氡（Rn-222）便携式探测器（RADIM 3型无源电子设备），测量了塞浦路斯各种建筑物和住宅内部空气中Rn-222的浓度。对于每个预选的建筑物和住宅，将校准的检测器放入封闭的房间，并以2至4小时的采样间隔记录Rn-222浓度，总计数时间通常为48小时。Rn-222放射性浓度范围为6.2至102.8 Bq/m**3，总体算术平均值为（19.3 +- 14.7）Bq/m**3。这一数值比世界平均值（人口加权）39 Bq/m**3低两倍。塞浦路斯人口的年总有效剂量当量计算为0.16至2.6 mSv，总体算术平均值为（0.49 +-0.37）mSv。
英文摘要：
Using high--sensitivity radon (Rn-222) portable detectors (passive electronic devices of the type RADIM3), the airborne Rn-222 concentration in the interior of various Cypriot buildings and dwellings was measured. For each preselected building and dwelling, a calibrated detector was put into a closed room, and the Rn-222 concentration was registered in sampling intervals of 2 to 4 hours for a total counting time of typically 48 hours. Rn-222 activity concentrations were found to be in the range of 6.2 to 102.8 Bq/m**3, with an overall arithmetic mean value of (19.3 +- 14.7) Bq/m**3. This value is by a factor of two below the world average (population-weighted) value of 39 Bq/m**3. The total annual effective dose equivalent to the Cypriot population was calculated to be between 0.16 and 2.6 mSv with an overall arithmetic mean value of (0.49 +- 0.37) mSv.
