在匈牙利埃格土耳其浴室的新旧建筑中采用了不同的氡测量方法，以制定氡测量协议。此外，还对氡和钍射气短寿命衰变产物、外源γ剂量和水氡进行了测量。个人测氡仪的应用提供了最准确的剂量估算结果。使用0.2和0.1测量的平衡因子，估计新老建筑物中氡及其短寿命衰变产物的年有效剂量分别为0.83和0.17 mSv。钍射气短寿命衰变产物的有效剂量仅为这些值的5%。相应的外部γ辐射有效剂量为0.19和0.12 mSv y（-1）。饮用含氡自来水的有效剂量为0.05 mSv·y（-1），饮用泉水的有效剂量为0.14 mSv·y（-1）。
Different radon measurement methods were applied in the old and new buildings of the Turkish bath of Eger, Hungary, in order to elaborate a radon measurement protocol. Besides, measurements were also made concerning the radon and thoron short-lived decay products, gamma dose from external sources and water radon. The most accurate results for dose estimation were provided by the application of personal radon meters. Estimated annual effective doses from radon and its short-lived decay products in the old and new buildings, using 0.2 and 0.1 measured equilibrium factors, were 0.83 and 0.17 mSv, respectively. The effective dose from thoron short-lived decay products was only 5 % of these values. The respective external gamma radiation effective doses were 0.19 and 0.12 mSv y(-1). Effective dose from the consumption of tap water containing radon was 0.05 mSv y(-1), while in the case of spring water, it was 0.14 mSv y(-1).
