摘　　要：Objective:To explore the concentration level of radionuclide in mushrooms in northeast China,and to analyze the risk of the effective dose of edible mushrooms to the human body.Methods:A total of 68 samples of 18 species of mushrooms from three regions in northeast China and Beijing as control were collected from 2017 to 2020.The activity of radionuclide in mushrooms was measured by gammaspectrometry,and the activity was analyzed by statistical analysis.The relationship between ^(137)Cs and ^(40)K content in mushrooms was explored.Results:^(238)U was undetected in all samples.The activity concentration of ^(226)Ra,^(232)Th,^(40)K,^(137)Cs were in range of 1–34.3,2.26–32.3,208–2,388 and 0.6–130.3 Bq/kg,respectively.The ^(137)Cs and ^(40)K concentrations in mushrooms were not correlated.The risk analysis of radioactivity in the collected mushrooms showed that the highest effective dose of the 18 kinds of mushrooms was 0.042 mSv.Conclusion:The radionuclide content of mushrooms in northeast China is within the normal range.The mushrooms will not cause risk to human health.
