新疆某测井公司非密封放射源应用的辐射水平调查与评价研究

文章将非密封放射源^131 Ba的应用过程分为贮存、分装、运输及测井阶段，开展不同阶段放射性水平状况调查，对调查结果进行剂量估算与现状评价，掌握新疆某测井公司非密封放射源^131 Ba的应用过程对环境和人员造成的辐射危害。贮存、分装、运输及测井阶段的分阶段辐射环境影响评价方法的提出，为今后开展放射性同住素测井辐射环境影响评价提供方法借鉴。

Investigation and Assessment of Radiation Level for Unsealed Radioactive Sources Used in a Logging Company of Xinjiang

This paper divided the application process of unsealed radioactive source 131 Ba into storage, packaging, transporta tion and logging phase, carried out the radioactive level survey in different stage, estimated the dose and assessed the current situ ation of the survey results, mastered the radiation hazards of unsealed radioactive sources 131 Ba using in a logging company of Xin jiang to the environment and staff. The radiation environmental impact evaluation method of storage, packaging, transportation and logging was proposed. It provided a reference for the radiation environmental impact evaluation of radioactive isotope logging for future.
