| 摘 要： | 利用RAD7便携式测氡仪和NR-67A型连续测氡仪测量了广东省一些温泉宾馆室内外氡浓度。从无人入住的宾馆房间内氡浓度的变化来看，土壤氡的渗入是底层房间氡的主要来源。当在浴室内使用温泉水洗浴时，客房内平均氡浓度水平比没有用温泉水时高出10．9％～813％，浴室内氡浓度比没有用温泉水洗浴时高出13．8％～489％。宾馆室内使用温泉水有较高的氡转换系数。某些宾馆室内氡浓度超标。可能对宾馆工作人员造成潜在健康危害，应采取一些管理措施或技术手段降低其暴露水平。

| Abstract: | The indoor and outdoor radon concentration in four hot spring hotels in Guangdong was measured by using RAD7 and NR-667A radon detectors and the sources of indoor radon were investigated. From the variation of radon levels in the closed,unoccupied hotel rooms, soil gas intrusion was found to be very important indoor radon source in hotel rooms with floors in contact with soil.When there was spring water bathing in the bath rooms, average radon levels were (10.9%)~813% higher in the hotel rooms and 13.8%~489% higher in bath rooms compared to their corresponding average levels when there was no spring water used. Spring water used in the hotel rooms showed higher radon transfer coefficients than those reported previously. Radon in some hotel rooms maintained much higher concentrations than the relevant guideline levels,thus might have potential health risks to the hotel employees.Therefore,technical and management measures should be taken to lower their exposure of radon through inhalation. |
