目的了解桂西山区自然环境γ辐射对当地居民健康的影响。方法用FD -71A型闪烁辐射仪 ,对室内外及道路环境的583个测试点进行γ辐射空气照射量率测定 ,并估算出当地居民年均吸收剂量。结果该地区环境γ辐射(本底)水平造成当地居民年均吸收剂量为72.34mGY/年。结论桂西山区属正常天然辐射地区 ,环境中天然γ辐射对当地长住居民健康无危害。
Objective To understand the effect of natural environment gamma radiation on the health of local residents in western Guangxi. Methods FD-71A scintillation radiometer was used to measure the radiation dose of γ-radiation to 583 test points in indoor and outdoor environment and to estimate the annual average absorbed dose of local residents. Results The level of ambient γ radiation (background) in the region caused the annual average absorbed dose of local residents to be 72.34 mGY / year. Conclusion The western Guangxi mountainous area belongs to the normal natural radiation area. The natural γ radiation in the environment is not harmful to the health of the local permanent residents.
