Radon-222 concentrations in the air of 12 tourist caves in Slovenia, Yugoslavia were measured. In almost all the caves concentrations are higher than in the outdoor air, with the highest concentration in the Tabor Cave at about 6000 Bq m-3. From the 222Rn concentrations obtained, the activity of 222Rn inhaled by a visitor breathing cave air was calculated, and the bronchial dose was estimated. The inhaled activity and the bronchial dose were highest in the Tabor Cave with values of 10 kBq and 540 microSv, respectively.
对南斯拉夫斯洛文尼亚12个旅游洞穴空气中的氡-222浓度进行了测量。几乎所有洞穴中的浓度都高于室外空气，塔博尔洞穴中的浓度最高，约为6000贝克勒尔/立方米。根据测得的222Rn浓度，计算出呼吸洞穴空气的游客吸入的222Rn活度，并估算了支气管剂量。塔博尔洞穴中的吸入活度和支气管剂量最高，分别为10千贝克勒尔和540微希沃特。
