摘　　要：平衡因子是氡子体所致剂量估算和评价的重要参数。为了解海南省温泉设施内不同空间空气中氡及氡子体平衡因子的水平与分布范围,本文采用连续测量方法对不同地域典型温泉设施内不同空间氡及氡子体浓度、室内温泉泡池加水过程氡及氡子体浓度进行现场测量,计算并分析平衡因子的变化。测量结果表明:平衡因子在较大范围内分布,通风状况是影响平衡因子的重要因素,通风越好,平衡因子越小;室内引入温泉水后,空气中氡及氡子体浓度升高,平衡因子略有上升。The equilibrium factor of radon and its progeny is an important parameter for estimation and evaluation of radiation doses contributed by radon progeny.In order to understand the level and distribution range of the equilibrium factors in different spaces inside hot spring facilities in Hainan Province,field investigation was carried out by this study.continuous measurement methods were used to measure radon and radon progeny concentrations simultaneously in different spaces in hot spring facilities in different regions in Hainan,and the hot water filling process of indoor hot spring pools was also investigated.The measurement results show that the equilibrium factor is distributed in a wide range,and ventilation conditions are an important factor affecting the equilibrium factor.In general indoors it could be concluded that the better the ventilation,the smaller the equilibrium factor.After the introduction of hot spring water indoors,the concentration of both radon and radon progeny increases,and the equilibrium factor also appeared in slight increased tend.
