A review of transfer distribution and content of radionuclides in mushrooms

Abstract

Since the Chernobyl nuclear accident, the radioactive contamination in food caused by the nuclear accident has been widely concerned by people. There have been a lot of studies on concentrated radionuclides in mushrooms in foreign countries, but the research on radionuclides content and transfer distribution mechanism of radionuclides in mushrooms is almost blank in China. Studies have shown that mushrooms have a strong adsorption capacity on radionuclides. As a common food in daily life, therefore, it is of great significance to study the content of radionuclides in mushrooms for evaluating the internal dose in the human body. In this paper, the types of radionuclides in mushrooms and the methods of their transfer and distribution in mushrooms were reviewed, and the research status and development trends at domestic and abroad in recent years were emphasized, in order to provide theoretical support for the future basic research. 摘要： 切尔诺贝利核事故后, 由核事故导致的食品中放射性污染受到广泛关注。国外对蘑菇浓集放射性核素已有大 量研宄, 而我国目前关于蘑菇中放射性核素含量及转移分布机理的研宄几乎处于空白。蘑菇作为人们日常消费的食 品, 研宄表明其对放射性核素具有较强的吸附作用, 因此开展蘑菇中的放射性核素含量研宄对评估人体内照射剂量具 有重要意义。本文综述了蘑菇中放射性核素的种类、蘑菇中放射性核素的转移分布研宄方法, 并重点阐述了近年来国 内外研宄现状, 旨在为今后的基础研宄提供理论支撑。
