Radiocaesium Contamination of Mushrooms at High- and Low-Level Chernobyl Exposure Sites and Its Consequences for Public Health

A study examined how much radioactive cesium collected in wild mushrooms from areas affected by the 1986 Chernobyl nuclear accident in Czech Republic. The findings showed that while mushrooms in the most contaminated area accumulated more radioactivity than those in less affected areas, eating these mushrooms would not cause significant health risks to most people. The research helps experts understand how to safely assess radioactive contamination in wild foods after nuclear accidents.

An evaluation of the occurrence and trends in 137Cs and 40K radioactivity in King Bolete Boletus edulis mushrooms in Poland during 1995–2019

This study tracked radioactive contamination in King Bolete mushrooms across Poland over 25 years following the 1986 Chernobyl nuclear accident. Researchers found that radioactive caesium levels were highest 10-20 years after the accident, peaking in the 1990s, because radioactive particles slowly moved deeper into soil where mushroom roots feed. While people who eat wild mushrooms from Poland were exposed to some radioactivity, serious health risks were uncommon, and contamination has significantly decreased in recent years.
