大型γ辐照装置对周围环境电离辐射的调查分析

Discuss the Ionizing Radiation Monitoring and Environment Survey about Aradiation Installations

通过对大型γ辐照装置周围环境的电离辐射监测与调查,并按照剂量学方法计算分析各相关工作人员及公众的年有效剂量,结果低于《电离辐射防护与辐射源安全基本标准》(GB18871-2002)中的剂量限值的四分之一。表明大型γ辐照装置的厂房辐射防护设施只要按照相关标准进行设计和建设,就不会对环境和公众产生附加剂量的照射。

In this paper ,through ionizing radiation monitoring and environment survey about γ radiation installations, analyzing and discussing practical dose data about occupation and public annual effective dose equivalent, the result is lower than the one fourth of dose limit from basic standards for protection against ionizing radiation and for the safety of radiation sources （GB 18871-2002）. As long as the protection against radiation installation is designed and built by basic standards, radiation installations do not product the addition dose to environment and public.
