摘要
对南方某核设施退役治理后的辐射环境进行了现场监测,并对当地辐射环境进行评价,评价结果表明:矿区及其周边地区空气中γ辐射吸收剂量率、氡及其子体浓度都低于国家管理限值水平,治理后土壤中氡析出率明显下降,土壤及地表水中放射性核素铀、镭含量较低,治理效果保持较好。
In this paper,a southern decommissioning of nuclear facilities after the treatment carried out on-site monitoring of the radiation environment,and evaluate the local radiation environment,the evaluation results showed that: the mine and surrounding area air γ radiation absorbed dose rate,radon and its progeny concentration limits are lower than the national level of management,after treatment the soil radon exhalation rate decreased,radionuclides in soil and surface water uranium,radium content is low,the governance effect of mine have been maintained good.
