The present work aims to assess the effective doses from long-term continual radon monitoring in six European caves (Slovenia, Slovakia and the Czech Republic), including influencing environmental factors. Caves are important radiation protection subjects because of elevated radon activity concentration (~kBq/m3), mostly due to the low natural ventilation. The sources of radon gas are most often underground rock layers and clastic sediments. The radon activity concentrations show seasonal variations, for which the outside temperature is the main driving force. The human health impact due to the radon inhalation in monitored caves was estimated through the annual effective dose, using the methodology provided by the International Commission on Radiological Protection (ICRP Publication 137). The annual effective dose could reach several tens of mSv, depending on the working hours spent in the underground.
本研究旨在评估在六个欧洲洞穴（斯洛文尼亚、斯洛伐克和捷克共和国）中进行长期连续氡监测的有效剂量，包括影响环境的因素。由于氡活度浓度较高（~kBq/m3），且通风条件较差，洞穴成为辐射防护的重要研究对象。氡气的主要来源通常是地下岩层和碎屑沉积物。氡活度浓度呈现季节性变化，室外温度是主要驱动因素。通过国际辐射防护委员会（ICRP 出版物 137）提供的方法，对监测洞穴中吸入氡气对人体健康的影响进行了估计，该方法基于年度有效剂量。由于在地下工作的时间不同，年度有效剂量可能达到几十毫希沃特。
