Radiation in nuclear facilities - centralized systems for continuous monitoring of radiation and or levels of radioactivity - part 2 : requirements for discharge , environmental , accident , or post - accident monitoring functions 核设施中的辐射.连续监测辐射和或放射性水平的中心系统.第2部分:对卸料,环境,意外事件或紧急事故监测功能的要求
Based on the results of investigations , this paper proposes some measures for the decommission of uranium geology laboratories and the disposed of radioactive substances , the environmental radioactivity level has been evaluated after treating these laboratories 本文在对铀矿地质实验室现状进行调查的基础上，介绍了铀矿地质实验室的退役治理方法，并对退役治理后的环境进行了环境放射性水平评价。
In order to verify the natural radioactivity level , of tin polymetallic ore in southeast yunnan , and find out radioactive pollution in mining , dressing and smelting processes , 10 tin ores in this area were chosen to measure radionuclides ' specific activity in each kind of tin polymetallic ore , undressed ore , ore concentrate , debris and smelting slag 摘要为查明滇东南锡多金属矿天然放射性水平，了解锡矿采、选、冶过程中的放射性污染，选择了该区10个锡矿山，测量了各类锡多金属矿原矿、精矿、尾矿及冶炼炉渣放射性核素比活度。
It is shown that the radioactivity level of tin polymetallic ore , undressed ore and adjacent formation is affected by the strata and mineralization type , the radioactivity level of sulfide ore is not high as a whole , while that of tin ore generally is several times higher than the background value and that of debris and slag is also relatively high , whose impact on the environment is not neglectable 锡多金属矿原矿及围岩放射性水平受地层与矿化类型影响很大，硫化矿整体放射性水平不高，砂锡矿却普遍高出背景值数倍，尾矿、炉渣放射性水平也相对较高，对环境的影响不容忽视。
This paper has discussed the airborne monitoring of radioactive contamination formed during exploitation and utilization of iron ore and coal ore , analyzed the gamma radiant eminence map of china , and determined several relatively high radioactivity level regions , thus showing the effects of airborne radioactivity survey 摘要通过对铁、煤开发利用中形成的放射性热点的成功航空检测，以及对中国辐射照射量率图的分析，确定了几个放射性水平偏高区域，从而阐明了航空放射性测量在环境检测中的作用。
