In order to estimate occupational exposure of workers in a therapeutic radon spa facility, radon concentration in the workplace air was investigated at Markhot Ferenc Hospital, Eger, Hungary. The investigated balneotherapeutic facility and its natural hot spa water are used for treatments and rehabilitations of rheumatic patients. Radon concentration, radon decay products at a bathhouse, treatment rooms and a consultation room were continuously measured in August and September 2018. In the present study, different levels of radon concentration among the observation sites and its clear temporal variations were found, though radon concentrations in the investigated sites were below 300 Bq m-3. Regarding such radon fluctuation and low equilibrium factor level (0.1), the annual effective doses of workers are estimated to be around 0.5 mSv year-1.
为了评估氡疗温泉设施中工人的职业暴露情况，在匈牙利埃格尔的马尔霍特·费伦茨医院对工作场所空气中的氡浓度进行了调查。被调查的浴疗设施及其天然温泉水用于风湿性疾病患者的治疗和康复。于2018年8月和9月持续测量了浴室、治疗室和咨询室的氡浓度及氡衰变产物。在本研究中，尽管被调查场所的氡浓度低于300 Bq m-3，但各观测点的氡浓度存在不同水平，且有明显的时间变化。考虑到这种氡浓度波动和较低的平衡因子水平（0.1），估计工人的年有效剂量约为0.5 mSv年-1。
