摘　　要：目的:探讨食品和饮用水的放射性核素指导水平。方法:根据国际组织发布的相关标准和技术文件,分析现存照射情况和应急照射情况下食品和饮用水放射性核素指导水平的计算方法。结果:给出现存照射情况饮用水中17种放射性核素指导水平,食品中20种放射性核素指导水平,以及应急照射情况下食品和饮用水中24种放射性核素指导水平。国内相关标准较为滞后,且缺乏饮用水放射性核素活度浓度指导水平标准。结论:我国食品和饮用水放射性核素指导水平标准应参考国际组织发布的标准,结合我国具体情况,制定或完善适合我国的食品和饮用水放射性核素指导水平标准,以更好保护我国公众健康。Objective： To investigate guidance levels of radionuclide for food and drinking water. Methods： According to the relevant standards and technical documents issued by international organizations, the computing methods of guidance levels of radionuclide for food and drinking water under the existing exposure situation and emergency exposure situation were analyzed and researched. Results： The calculated guidance levels of 17 radionuclides in drinking water and 20 radionuclides in food in existing exposure situation were provided, and the guidance levels of 24 radionuclides in food and drinking water in emergency exposure situation also were proposed. It was found that the relevant standards in China were lag and the standard of guidance levels of radionuclides activity concentrations for drinking water were deficient. Conclusion： It is suggested that the standards of guidance levels of radionuclide for food and drinking water in China should be formulated or revised by referring to international standard that issued from international organization and taking into account the specific conditions in China so as to preferably protect public health of our country.
