Nuclear accidents, despite having an extremely low probability of occurrence, could cause uncontrolled release of radioactive elements (fission and activation products) into the environment, and may ultimately lead to contamination of food products. Such a scenario requires extraordinary measures for control of food, which might be contaminated to a level not suitable for human consumption. Agricultural products (which include grain crops, vegetable, fruits, dairy, meat, eggs and poultry) pass through a series of local, district and state level markets to finally reach consumers. An effective intervention at different stages of distribution by targeted sampling and analysis of suspected (contaminated) foodstuffs will substantially reduce the chances of contaminated food to reach the public. At the same time, it will also ensure food security of the people without imposing unreasonable restrictions in market flow. This can also help in getting the farmers adequately compensated. This paper presents a protocol for sampling and analysis suitable for India, considering the diversity with respect to climate, soil type, land use, crop pattern, population density, etc. The paper also provides an estimate of infrastructure requirement to carry out environmental monitoring following the emergency with respect to human resources and instruments. The paper proposes to use the national web portal for collection of data pertaining to crop pattern, land use and market flow. A web-based decision support system (Web-DSS) on a GIS platform, for sampling, analysis and display of data online would enhance the transparency of decision being taken and enable the administrators to effectively monitor the work flow, details of sample collection, analysis and effective use of human and other resources.

尽管发生核事故的可能性极低，但核事故仍可能导致放射性元素（裂变和活化产物）不受控制地释放到环境中，并最终导致食品污染。这种情况需要采取特殊措施来控制食物，这些食物可能被污染到不适合人类食用的水平。农产品（包括谷物，蔬菜，水果，奶制品，肉，蛋和家禽）通过一系列地方，地区和州一级的市场最终到达消费者手中。通过对可疑（受污染）食品进行有针对性的采样和分析，在分配的不同阶段进行有效干预，将大大减少受污染食品进入公众的机会。同时，它还将确保人民的粮食安全，而不会对市场流通施加不合理的限制。这也可以帮助农民获得适当的补偿。考虑到气候，土壤类型，土地利用，农作物类型，人口密度等方面的多样性，本文提出了一种适用于印度的采样和分析协议。人力资源和工具方面的紧急情况。该文件建议使用国家门户网站收集有关作物形态，土地利用和市场流量的数据。基于GIS平台的基于网络的决策支持系统（Web-DSS），用于抽样，
