Abstract:
Nuclear weapon tests and nuclear leakage accidents have resulted in worldwide contamination by radionuclides, and 137Cs persists in the environment because of its long half-life. Due to their radionuclide-enrichment properties, wild edible mushrooms take up 137Cs from the surrounding matrix and store it in their fruiting bodies, thus becoming an indicator medium for radionuclide contamination and can be used to evaluate soil contamination with radionuclides. However, there are large variations in 137Cs activity concentrations in different wild edible mushrooms depending on regions, species, and lifestyles. Therefore, it is important to carry out the detection of 137Cs in wild edible mushrooms to understand the mechanisms of 137Cs transfer distribution and enrichment and to monitor the environment. This paper reviews the studies on 137Cs in wild edible mushrooms in recent years both in China and other countries. This article analyses the content of 137Cs in wild edible mushrooms in different regions, the transfer process from soil to wild edible mushroom fruiting bodies, and the distribution of 137Cs in wild edible mushrooms. These results provide theoretical support for the future monitoring of radionuclides in wild edible mushrooms on a nationwide scale, the establishment of relevant databases, and in-depth research on the mechanism of radionuclide transfer.
