对金山金矿田的金山金矿、花桥金矿区露天水源天然铀、氡， 居民区和井下作业人员γ外照射有效剂量等进行调查的结果表明： 金山、西蒋矿区露天水源天然铀、氡浓度均小于限值０．０５ ｍ ｇ／Ｌ和３７．００ Ｂｑ／Ｌ， 空气氡浓度为０．００８～０．０１３ Ｂｑ／Ｌ． 居民和井下作业人员γ外照射年有效剂量均小于１ ｍ ｓ 和５ ｍ ｓ． 矿区放射性均在国家规定的环境评价指标限制之内， 对矿山的人身和环境无影响
The results of surveying the effective dose of γ radiation of open source natural uranium, radon, residential area and downhole workers in Jinshan Gold Mine and Huaqiao Gold Mine of Jinshan Gold Mine show that open source natural uranium, Radon concentrations were less than the limits 0.05 m g / L and 37.00 Bq / L, radon concentration 0.008 ~ 0.013 Bq / L. The effective doses of γ ray irradiation by inhabitants and underground workers are less than 1 m s and 5 m s respectively. Mining radioactive are within the limits of environmental assessment indicators prescribed by the state, the mine’s personal and environmental impact
