【摘要】 目的在既往调查的基础上,进一步了解当地居民、游客、治疗疾病的患者的洗浴模式等情况,并对当地的室内外氡浓度进行测量。方法采用ATD短期累积测量法和连续测量法测量室内外氡浓度,并与国家相关标准进行对比。结果室内外氡浓度几乎全部高于电离辐射防护与辐射源安全基本标准(GB18871-2002)中的住宅中氡持续照射的优化行动水平400Bq/m3(平衡因子0.4)。部分浴室中氡浓度高于地热水应用中放射卫生防护标准(GBZ124-2002)中地热水浴疗室平衡当量氡浓度400Bq/m3的控制限值。结论降札温泉室内外氡浓度水平非常高,会对附近的居民、游客和患者的健康造成影响。更多还原

【Abstract】 Objective To survey the indoor and outdoor radon concentrations in the air in Jiangzha radon spring area.Methods The indoor and outdoor radon concentrations were detected by using ATD short-term accumulative and continuous measurements,and compared with the national standards.Results The indoor and outdoor radon concentrations nearly exceed the residential radon action level of 400Bq/m3(equilibrium factor 0.4)in continuous exposure set in Ionizing Radiation Protection and Basic Standard of Safety of Radiation Sources(GB18871-2002).The radon concentration in the air in some bathroom were higher than limit of equilibrium equivalent radon concentration 400Bq/m3 for treatment purpose set in Radiological protection standards for using geothermal water(GBZ124-2002).Conclusion The indoor and outdoor radon concentration levels in the air was very high in Jiangzha radon spring area,which could be harmful to the health of the people living there,visitors and patients.更多还原
