Measuring radioactivity in food samples.

项目摘要 美国食品药品监督管理局（FDA）法规事务办公室（ORA） 联邦-州关系委员会先前授予沃兹沃斯中心的核化学 实验室与合作协议的设备，用品，人员，培训， 设施升级。作为食品紧急反应网络（FERN）实验室， 沃兹沃斯中心的目标是保持和提高其处理激增容量的能力 用于分析食品和食品产品以应对放射性威胁或其他 紧急情况下，通过林业发展局继续提供资金。食品和食品包括 进口和成品（即食）食品，如：蔬菜，水果，果汁，谷物和 谷物产品、海鲜和其他鱼类产品、牛奶和其他乳制品、婴儿配方奶粉， 婴儿食品、瓶装水、调味品和酒精饮料。 通过培训，提高了放射性准备状态， 加强我们目前的监测计划和分析方法的发展。在 与FDA合作，快速分析受污染食品的替代方法是 正在调查 FDA向核化学提供的额外计数仪器 实验室（高纯度锗伽马射线探测器和低本底液体） 闪烁计数器）进行了校准，并用于测试现有的和新的分析 方法.这些仪器提高了我们的样品分析能力。 这一正在进行的项目的成果之一将是编写一份方法简编， 放射性物质食品的制备和分析。这些方法正在制定 其他与FERN相关的实验室可在eLEXNET上查阅。 我们的实验室协调了菜单2010年国家演习，其中包括 规划、制备729份食品样品，分发给37个国家和国际组织 实验室和样品验证。我们的实验室将继续参与此类活动， 加强FERN FDA实验室应急响应的重要演习。

PROJECT SUMMARY The Food and Drug Administration (FDA), Office of Regulatory Affairs (ORA), Division of Federal-State Relations previously awarded the Wadsworth Center's Nuclear Chemistry Laboratory with a cooperative agreement for equipment, supplies, personnel, training, and facility upgrades. As a Food Emergency Response Network (FERN) laboratory, the Wadsworth Center's objective is to maintain and increase its ability to handle surge capacity for the analysis of food and food products in response to radiological threats or other emergency situations through continued FDA funding. The food and food products include imported and finished (ready-to-eat) foods such as: vegetables, fruits, juices, grains and grain products, seafood and other fish products, milk and other dairy products, infant formula, baby foods, bottled water, condiments, and alcoholic beverages. An improved state of radiological preparedness has been achieved through training, enhancement of our current surveillance program, and analytical method development. In cooperation with the FDA, alternative methods for rapid analyses of contaminated foods are being investigated. The additional counting instruments provided by FDA to the Nuclear Chemistry Laboratory (high-purity germanium gamma-ray detectors and a low-background liquid scintillation counter) have been calibrated and used to test existing and new analytical methods. These instruments have increased our sample analysis capacity. One of the outcomes of this ongoing project will be a compendium of methods for preparation and analysis of foods for radiological materials. These methods are being made available on the eLEXNET for other FERN-related laboratories. Our laboratory coordinated the MENU 2010 National Exercise, which included planning, preparation of 729 food samples, distribution to 37 national and international laboratories, and sample verification. Our laboratory will continue to participate in such important exercises to enhance FERN FDA laboratory emergency response.
