摘要 项目七：得克萨斯州化学家食品辐射危害防御 OTSC-AAS放射化学食品防御项目的计划包括：1）扩大 放射化学方法检测放射性核素，2）扩大ISO/IEC 17025：2017范围 包括α、β和γ测试，3）参与FDA要求的年度监测 支持和保持准备状态的活动，4）参加国家安全事件演习 5)保持准备状态，对怀疑或确认的蓄意 涉及人类或动物食品的污染事件，包括确保分析人员接受培训， 已通过能力练习，设备处于正常工作状态，试剂和用品 6）参与与可疑或可信的食品威胁相关的检测 和动物食品供应，其中应FDA的要求怀疑存在放射性物质。在2019年， OTSC进行了广泛的准备工作，并为设计分配了必要的预算， 开发一个新的放射性实验室，以参与食品紧急反应网络 （Fern）.原子能机构申请并收到了放射性材料许可证，作为 德克萨斯A&M大学（TAMU）环境健康和安全（EHS）放射性许可证 2019年9月。该机构目前有一个堪培拉系列5 XLB气体比例α/β 计数器和两个堪培拉HPGe伽马射线计数器，两个Ortec HPGe伽马射线计数器 光谱仪和普林斯顿伽马分光光度计。二次仪表 包括Ludlum 14 C测量仪，带有44-2伽马闪烁体和44-9 Pancake GM 检测器该机构制定并实施了操作和安全程序，以满足所有 TAMU环境健康与安全部通过其 许可证与得克萨斯州卫生服务部，辐射控制局和 美国核管理委员会。作为该项目的成果，德克萨斯州动物食品防御 将加强对放射性危害的认证，扩大ISO认证的范围， 提高能力，并为食品监管机构提供快速反应能力， 放射性灾难的发生。

Abstract PROJECT SEVEN: Texas State Chemist Food Defense for Radiological Hazards Plans for the OTSC-AAS radiochemistry food defense project include: 1) expansion of radiochemistry methodology to detect radionuclides, 2) expand the ISO/IEC 17025:2017 scope to include alpha, beta, and gamma testing, 3) participation in FDA requested annual surveillance activities to support and maintain readiness, 4) participation in national security event exercises 5) maintenance of preparedness to rapidly respond to the suspected or confirmed intentional contamination event involving human or animal food including ensuring analysts are trained and have passed competency exercise, equipment is in working order and reagents and supplies are available, and 6) participation in testing associated with suspected or credible threats to the food and animal food supply where a radiological agent is suspected at the request of FDA. In 2019, OTSC conducted extensive preparations and allocated necessary budgets for the design and development of a new radiological lab to participate in the Food Emergency Response Network (FERN). The agency applied and received a radioactive material (RAM) permit as part of the Texas A&M University (TAMU) Environmental Health and Safety (EHS) radiological license in September 2019. The agency currently has a Canberra Series 5 XLB gas proportional alpha/beta counter and two Canberra HPGe gamma spectrophotometers, two Ortec HPGe gamma spectrophotometers, and a Princeton gamma tech spectrophotometer. Secondary instrumentation includes a Ludlum 14C survey meter with a 44-2 gamma scintillator and a 44-9 Pancake GM detector. The agency developed and implemented operating and safety procedures to meet all regulatory requirements imposed by TAMU Environmental Health and Safety, through their licenses with the Texas Department of State Health Services, Bureau of Radiation Control and US Nuclear Regulatory Commission. As an outcome of this project, Texas animal food defense for radiological hazards will be strengthened and scope of ISO accreditation expanded resulting in capacity and capability increased and provide surge capacity for food regulatory agencies in the event of a radiological disaster.
