摘　　要：对某退役治理后的铀矿山废石堆场按20m×20m网格均匀布点进行贯穿辐射剂量率监测和地表222Rn析出率监测,报道了监测结果,并对仪器的宇宙射线响应值扣除方法、γ辐射剂量率与222Rn析出率关系、覆盖土中添加阻滞剂CaO对覆土掩埋治理效果的影响进行了探讨,对铀矿山环境治理具有参考价值。This paper shows the monitoring results that the penetrating radiation dose rate and the separation rate of earth surface ^(222)Rn were monitored by a network-fixed point of 20m×20m after treatment of a certain decommissioned uranium mine waste residue site. It also discusses the deduction of the response value of the instruments to the cosmic rays, the relations between γ-radiation dose rate and the separation rate of ^(222)Rn,and the influence of CaO added to the coverin soil on the effectiveness of landfiu treatment. This is available for reference to harness the uranium mine environment.
