Health effects of radon on the human body have always been a hotspot in medical, chemical, nuclear physical and some other researching area. In recent years, the academia have studied on the sources of radon (rocks and groundwater) . the influence factors of radon concentration (geologic factors, cave structure, meteorological parameters inside and outside the cave), radon concentration measurement (measuring object, measuring instruments and methods), the harm of radon, radon prevention and control (to isolate radon infiltration, enhance ventilation to reduce radon, reasonable arrangement of schedule to reduce the inhaled amount, strengthen monitoring) and some achievements have been got, but weak in the following researches such as the formation mechanism of radon in karst caves, establishment of karst cave radon measurement standards and effective dose estimates, controlling techniques of radon in karst caves and health management of show cave staff.%氡对人体健康的影响向来是医学、化学、核物理学等学科的研究热点.近年来学术界虽然对喀斯特洞穴氡的来源(岩石、地下水)、氡浓度的影响因素(地质因素、洞体结构、洞内外气象参数)、氡浓度的测量(测量对象、测量仪器及方法)、氡的危害、氡的防治(隔离氡气渗入途径、排风通氡、控制洞穴内停留时间减少吸入量、加强监测)等方面开展了研究并取得了不少的成果,但对于喀斯特洞穴氡的形成机理、喀斯特洞穴氡测量标准的制定及有效剂量的估算、喀斯特洞穴氡的防治技术及员工的健康管理等方面的研究还比较薄弱,有待加强.
