中文摘要:

      放射性核素通过食品传递到人体能够给人体带来伤害, 为此国际食品法典委员会制定了放射性核素限量要求。各国根据其国情亦制定了针对性的放射性核素限量标准, 且不同时期限量要求不同。本文通过介绍国际食品法典委员会、中国、日本、美国、欧盟等国在食品中放射性核素限量要求, 其中包含有紧急情况下限量要求, 比较不同国家食品放射性核素限量差异, 解读现阶段国际食品法典委员会指导水平对各国总体指导意义, 阐述各国限量水平依各国实际差异较大的部分原因, 各国食品中放射性核素限量要求能够保护贸易国公民放射性基本安全。

英文摘要:

      Radionuclides can transfer to human body through food, which could be harmful to human body. Therefore, the international Codex Alimentarius Commission (CAC) formulated the radionuclides limitation requirements, and different countries also developed targeted national standards according to their national conditions, with different limitation requirements in different time. By introducing the radionuclides limitation requirements in food of the international CAC, China, Japan, the United States, the European Union and other countries, especially emergency limitation requirements, this paper compared different radionuclides limitation requirements in food of different countries, interpreted the overall significance to each country of present guidance from the international CAC, and partly elaborated the reason why there were such obvious differences among the requirements. Each country’s radionuclides limitation requirements in food are very good protection to citizens’ radiological safety of trading nations.
