Radiochemistry Capacity/Capability Development Expansion of Alpha or Beta Radionuclide Testing Capabilities

总结（总体） 伊利诺伊州应急管理局（IEMA）的长期目标之一是加强 与FDA的合作。希望这种合作将使IEMA能够发展和加强 它对粮食能力进行放射性分析，同时为国家努力作出贡献。如果发生大规模的 核事故或放射性事故时，需要迅速分析和报告大量食品样本， 准确地说（坎宁安2014）。食物样本的放射性结果可以用来帮助官员 保护公众健康的明智决策/行动（EPA 2017）。IEMA的目标是准备好 放射化学实验室就为了这样的事件。该实验室目前已配备并准备好用于 对食品进行伽马放射性核素分析。然而，我们缺乏筛选食物的经验， α和（或）β发射体和原子能机构目前的液体闪烁计数器处于或接近于2005年年底， 其使用寿命。因此，IEMA正在通过这种放射化学分析开发寻求支持 与FDA的科学专业知识相结合的机会，以帮助发展机构的能力， 筛查食物中的α和/或β发射体。如果原子能机构获得这一机会， 林业发展局将通过培训和面对面会议得到加强。完成后，放射化学 实验室将展示筛选α和/或β发射体的能力，并准备好接受呼叫 参加放射性国家安全演习、监测测试活动和放射性事件。 作为食品紧急反应网络的成员，IEMA放射化学实验室建议： 通过请求购买PerkinElmer Quantulus来扩大国家alpha和beta分析能力 GCT LSC 6220 TR低活度液体闪烁计数器，包括α/β鉴别软件 （PerkinElmer 2020）。在一年的项目时间内，工程处将采购、安装、设置和校准 仪器工作人员将接受FDA选定的α和β食品分析方法的培训， 发射器使用液体闪烁计数。方法将经过验证，然后成功 验证方法的能力证明。IEMA管理层将支持差旅， 选定的工作人员参加年度实验室灵活资助模式面对面会议。的 项目目标将通过管理层强调成功地扩大我们的放射性 食品快速应急分析，特别是非伽马放射性核素分析。这项建议是 在放射化学实验室工作人员的经验和教育以及 新改造和装备的湿化学实验室的可用性。如上所述，IEMA的目标是 做好准备，参加放射性国家安全演习、监测测试活动， 辐射事故。

SUMMARY (Overall) One of the Illinois Emergency Management Agency’s (IEMA) long term objectives is to strengthen the Agency’s collaboration with the FDA. It is hoped that this collaboration will allow IEMA to develop and enhance its radiological analyses of food capability while contributing to the national effort. In the event of a large scale nuclear or radiological incident, a high load of food samples will need to be analyzed and reported rapidly and accurately (Cunningham 2014). The food sample radiological results can then be used to help officials make well informed decisions/actions to protect public health (EPA 2017). It is IEMA’s objective to ready the Radiochemistry laboratory for just such an event. The laboratory is currently equipped and prepared for the analysis of foods for gamma emitting radionuclides. However, we lack the experience to screen foods for alpha and/or beta emitters and the Agency’s current liquid scintillation counters are at, or close to, the end of their serviceable life. IEMA is thus seeking support through this radiochemistry analytical development opportunity in conjunction with the FDA’s scientific expertise to assist in developing the Agency’s capability to screen foods for alpha and/or beta emitters. If the Agency is awarded this opportunity, collaboration with the FDA will be enhanced, through training and a face-to-face meetings. When completed, the Radiochemistry laboratory will demonstrate competency for screening alpha and/or beta emitters and will be ready for the call to participate in radiological national security exercises, surveillance testing activities and radiological incidents. As a member of the Food Emergency Response Network, the IEMA Radiochemistry laboratory proposes to expand the national alpha and beta analysis capacity though its request to purchase a PerkinElmer Quantulus GCT LSC 6220TR low activity liquid scintillation counter which includes alpha/beta discrimination software (PerkinElmer 2020). Within the one year project time, the Agency will procure, install, set-up and calibrate the instrument. The staff will train on the FDA selected method(s) in the analysis of food for alpha and beta- emitters using liquid scintillation counting. The method(s) will be validated followed by the successfully demonstration of competency in the validated method(s). IEMA management will support travel to send a selected staff members to attend the annual Laboratory Flexible Funding Model Face-to Face meeting. The project aims will be accomplished through Management’s emphasis on successfully expanding our radiological rapid emergency response analysis of foods, especially for non-gamma emitting radionuclides. This proposal is supported by the strength of the Radiochemistry laboratory’s staff experience and education and the availability of the newly remodeled and equipped wet chemistry laboratory. As noted above it is IEMA’s goal to be ready for the call to participate in radiological national security exercises, surveillance testing activities and radiological incidents.
