摘  要:本文以石油测井公司退役场所为研究对象调查其辐射环境影响,包括退役场所的集装箱式非密封放射性同位素库及周围衰变池(蒸发池)等周围区域的γ辐射水平和表面沾污。结果表明,按照公司退役方案进行实施的集装箱式非密封放射性同位素库内遗留的设备和用品满足清洁解控的要求。退役过程中原则上不会产生放射性废物,因此退役过程中不会对工作人员和环境造成辐射影响。This paper takes the decommissioning site of petroleum logging company as the research object to investigate the radiation environmental impact, including the containerized unsealed radioisotope library and the surrounding decay pool (evaporation pool) in the decommissioning site γ radiation levels and surface contamination. The results show that the equipment and supplies left in the container type unsealed radioisotope library implemented according to the company’s decommissioning plan meet the requirements of cleaning and decontrol. In principle, no radioactive waste will be generated during the decommissioning process, so there will be no radiation impact on staff and the environment during the decommissioning process.
