摘要
目的 通过系统评价水泥生产企业在线元素分析仪用放射源对周围环境的辐射影响,为该类型放射源应用场所辐射监测及安全管理提供科学依据。方法 对 广西15家使用锎-252(^(252)Cf)核素在线元素分析仪的水泥生产企业进行统计分析,开展辐射安全管理现场调查及辐射环境现场监测,根据监测、调查结果进行评价。结果 含^(252)Cf源的在线元素分析仪使用场所周围环境γ辐射周围剂量当量率及中子周围剂量当量率虽有升高,但均能满足《含密封源仪表的放射卫生防护要求》(GBZ 125-2009)的要求。结论 在当前的使用和管理条件下,该类型放射源的应用对周围环境的辐射影响是可控的,不会对公众健康和环境安全造成危害。然而,仍需持续加强辐射安全管理措施,定期开展辐射监测工作,确保放射源的安全使用,以进一步降低潜在的辐射风险,为水泥生产企业在线元素分析仪用放射源的安全应用提供有力保障。
Objective To systematically evaluate the radiation impact of radioactive sources used in online elemental ana-lyzers in cement enterprises on the surrounding environment,and to provide a scientific basis for radiation monitoring and safety management at the application sites of this type of radioactive sources.Methods A statistical analysis was conduc-ted on 15 cement enterprises in Guangxi Province using online elemental analyzers with ^(252)Cf as the radioactive source.On-site investigation of radiation safety management and on-site monitoring of radiation environment were performed,followed by an evaluation based on the collected data.Results Although the gamma radiation ambient dose equivalent rate and neutron ambient dose equivalent rate increased around the sites using online elemental analyzers with ^(252)Cf as the radioactive source,they all met the requirements of the Radiological Health Protection Requirements for Instruments with Sealed Sources(GBZ 125—2009).Conclusion Under the current usage and management conditions,the application of this type of radioactive sources has controllable radiation impact on the surrounding environment,and will not pose a threat to public health and environmental safety.However,continuous strengthening of radiation safety management measures and regular radiation monitoring work are still needed to ensure the safe use of radioactive sources,further reducing potential radiation risks and providing strong guarantees for the safe application of radioactive sources in online elemental analyzers in cement enterprises.
