In many countries, caves can pose an economic interest for the authorities and stakeholders. The development of a show cave requires, apart from the conservation issues, to ensure the human safety by minimising the exposure to radon for cave personnel and visitors. Radon levels can vary widely from cave to cave, being directly correlated with different internal and external factors. It is therefore important to monitor radon levels before establishing the number of personnel required, so that they are not exposed to health-threatening levels of radiation. A long-term radon survey was carried out for this purpose in five show caves of Romania. The study pointed out the existence of high-radon potential areas inside the caves with concentrations reaching up to 4024 Bqm-3, thus posing radiological hazard to cave personnel and researchers who develop activities underground. Further research focused on personal dosimetry will be necessary for an efficient management of occupational risk.
在许多国家，洞穴对当局和利益相关者可能具有经济利益。除了保护问题外，开发一个供人参观的洞穴还需要通过尽量减少洞穴工作人员和游客接触氡的机会来确保人身安全。不同洞穴中的氡水平差异很大，这与各种内部和外部因素直接相关。因此，在确定所需人员数量之前监测氡水平非常重要，这样他们就不会暴露在对健康构成威胁的辐射水平下。为此，在罗马尼亚的五个供人参观的洞穴中进行了一项长期氡调查。研究指出，洞穴内存在高氡潜力区域，浓度高达4024贝克勒尔每立方米，从而对在地下开展活动的洞穴工作人员和研究人员构成辐射危害。为了有效管理职业风险，有必要进一步开展侧重于个人剂量测定的研究。
