Radon-222, a naturally occurring radioactive gas, responsible together with its progeny of around 50% of the average effective dose received by the population, has not been regulated by law until the recent Directive 2013/51 /Euratom. Its transposition into Spanish legislation was made in the recent RD 314/2016, which sets at limit value of 500 Bq l-1 for radon-222 in water for human consumption. Intercomparison exercises, such as those carried out by IPROMA SL and the Laboratory of Environmental Radioactivity of the Cantabria University (LARUC) in November 2015 and December 2016, represent the most useful tool available for detecting problems and taking corrective actions necessary for an efficient measurement by part of the laboratories. The participants in these exercises used three techniques: liquid scintillation counting, gamma spectrometry and desorption followed by ionisation chamber detection.
氡-222是一种天然存在的放射性气体，与其子体共同导致了人群所接受的平均有效剂量的约50%，直到最近的2013/51/Euratom指令出台，它才受到法律监管。其纳入西班牙法律是在最近的RD 314/2016中实现的，该法规将供人类消费的水中氡-222的限值设定为500 Bq l-1。比对活动，例如IPROMA SL和坎塔布里亚大学环境放射性实验室（LARUC）在2015年11月和2016年12月开展的活动，是检测问题以及采取必要纠正措施以使各实验室进行高效测量的最有用工具。这些活动的参与者使用了三种技术：液体闪烁计数法、伽马能谱法以及解吸后电离室检测法。
