广西糖厂放射源应用辐射环境影响监测与评价

目的 掌握广西辖区内糖厂密封放射源的使用分布情况，评价密封放射源对周围环境、职业人员、公众成员产生的辐射影响，为今后糖厂放射源的使用管理提供科学依据。方法 按监测规范合理布点，利用γ辐射剂量率仪对广西区内所有使用密封放射源的糖厂开展辐射环境现场测量，根据监测结果进行估算，并结合个人剂量监测结果进行分析。结果 密封放射源使用场所周围辐射剂量率高于环境本底水平，职业人员、公众成员会受到一定的辐射剂量。结论 职业人员及公众成员年有效剂量结果符合相关要求。

Monitoring and evaluation of environmental impact from radioactive sources applied in sugar factories in Guangxi

Objective To acquaintance the distribution of sealed radioactive sources used in sugar factories in Guangxi and evaluate the radiation effects on the surrounding environment, occupational staff, and the public. To provide scientific basis for the use and management of the sealed radioactive source in sugar factories.Methods According to the monitoring specifications, the gamma dose rate meter was used to measure the radiation environment of all sugar factories using sealed radioactive sources in Guangxi. The impacts were estimated based on the monitoring results, and combined with the monitoring individual doses.Results The gamma dose rates around the sites using sealed radioactive sources were higher than the environmental background level, and occupational workers and members of the public would receive a certain radiation dose.Conclusion The annual effective doses of ccupational staff and members of the public meet the relevant requirements.
