The measurement of radioactivity in food and agricultural ecosystems is an essential task for keeping the population safe after a nuclear emergency. Prior to the Tokyo Electric Power Company's Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident in 2011, the probability of such an accident, combining complex effects of natural and technical factors, was not reflected in detail in national emergency preparedness guidelines. The lack of such guidelines resulted in a limited efficiency response to the Fukushima accident in agriculture. This outcome showed a need for the preparation of such guidelines as a part of emergency preparedness for nuclear and radiological emergences. This paper provides information and generic, non-country-specific guidance on approaches to sampling food. The paper is intended for scientists, policy makers and decision makers involved in nuclear emergency preparedness and responses, particularly on large scales and at different stages of nuclear emergency based on lessons learned from the FDNPP accident.

日本核紧急情况下对农业土壤和食物的大规模采样和放射性分析：食品检验和采样随时间的变化。

粮食和农业生态系统中放射性的测量是在核事故发生后确保民众安全的一项重要任务。在2011年东京电力公司福岛第一核电站事故（FDNPP）发生之前，国家自然灾害应急准备指南中没有详细反映这种事故的可能性，并结合了自然因素和技术因素的复杂影响。缺乏这样的指导方针导致对福岛农业事故的效率响应有限。这一结果表明，有必要编写此类准则，作为对核和放射紧急情况进行应急准备的一部分。本文提供了有关食物采样方法的信息和非特定国家的通用指南。该论文供科学家使用，
