摘　　要：目的 对降扎温泉周围的辐射水平进行调查,分析污染的来源.方法 采用固体径迹探测器、氡及子体连续测量装置,γ剂量率仪测量了温泉生活区及周边环境的氡、氡子体浓度及γ照射量率.结果 温泉水中氡浓度为23 ～ 764 Bq/L,生活区室内、室外及浴场中氡的浓度分别为254 ～ 876 799、688 ～ 709和3590 ～ 15 299 Bq/m3;室内外γ照射量率分别为205 ～ 28 718和4104 ～18 254 nGy/h.结论 降扎温泉是目前发现的异常高氡和高天然辐射区,其辐射水平和健康影响应引起关注.Objective To investigate the radiation level around Jiangzha hot spring,and to analyze the sources of pollution.Methods The radon and its progeny concentration,γ dose rate in hot spring living district and surrounding area were measured with ATD monitors,radon and WL continuous measurement devices,γ dose rate meter.Results The radon concentration in water was 23 -764 Bq/L.Radon concentration indoors,outdoor and in bathing place were 254 -876 799,688 -709 and 3590-15 299 Bq/m3,respectively.γ dose rate were 205 -28718 nGy/h indoor,4104- 18254 n Gy/h outdoors.Conclusions Jiangzha hot spring is an area with rare high radon and high nature radiation.Its radiation level and health effects are worthy for further attention.
