Mushrooms from any possibly contaminated areas might be a good food to avoid for a very long while.

"Mushrooms That Absorb Radioactive Cesium 137 and Other Radionuclides"

"The lingering effects of the Chernobyl nuclear catastrophe in 1986 in Ukraine continue to affect entire eco-systems in Europe. An example of such effects is the radioactive contamination (cesium-137 contamination) of wild mushrooms in certain European countries["/b].

"With the recent developments at the Fukushima Daiichi nuclear plant in Japan and the uncertainty of the consequences of the disaster, the topic of nuclear contamination of food has re-gained considerable public attention over the past weeks."


"Mushrooms' Affinity for Cesium-137 and Other Radionuclides"

"Fungi, which lack stems and roots, use absorption to obtain nutrition from the atmosphere through their surface cells. As a result, they are prone to absorbing radioactive substances such as cesium-137 (also known as caesium-137, radiocaesium-137 and 137 Cs) and other radionuclides. Cesium is one of the by-products of nuclear fission processes in nuclear reactors and nuclear weapons testing. The Chernobyl power plant released significant amounts of radiocesium-137 into the environment, but also the nuclear weapons tests in the 1950s and 1960s released some cesium."

The half-life of cesium-137 is 30 years and it is associated with an increased risk of cancer.
