Caves and mines are considered to be places of especial risk of exposure to (222)Rn. This is particularly important for guides and workers, but also for visitors. In the Extremadura region (Spain), there are two cave systems in which there are workers carrying out their normal everyday tasks. In one, visits have been reduced to maintain the conditions of temperature and humidity. The other comprises several caves frequently visited by school groups. The caves were radiologically characterised in order to estimate the dose received by workers or possible hazards for visitors.
洞穴和矿井被认为是特别容易接触到（222）氡的地方。这对导游、工人以及游客来说都尤为重要。在西班牙的埃斯特雷马杜拉地区，有两个洞穴系统，里面有工人在进行日常工作。在其中一个洞穴系统中，为了维持温度和湿度条件，参观次数已有所减少。另一个洞穴系统包含几个经常有学校团体参观的洞穴。对这些洞穴进行了放射性特征分析，以估算工人所接受的剂量或对游客可能存在的危害。
