Imleria badia such as food expert Antonio Carluccio, and is sold in markets in Europe and central Mexico. Its mushrooms are less often infested by maggots than other boletes. Several European studies have demonstrated that the mushroom can bioaccumulate some trace metals from the soil, such as mercury, cobalt, and nickel. Additionally, the mushroom contains a pigment that concentrates radioactive caesium; specimens collected in Europe following the 1986 Chernobyl disaster contained several times more caesium-137 than those collected before the incident. The bay bolete was first named as "Boletus castaneus" ß "badius" (i.e. a subspecies of "Boletus castaneus") by Elias Magnus Fries
Radioactive waste not include amounts that have escaped into the environment from accidents or tests. Japan estimated to hold 17,000 tons of HLW in storage in 2015. HLW have been shipped to other countries to be stored or reprocessed, and in some cases, shipped back as active fuel. The radioactive waste from spent fuel rods consist primarily of cesium-137 and strontium-90, but it may also include plutonium, which can be considered a transuranic waste. The half-lives of these radioactive elements can differ quite extremely. Some elements, such as cesium-137 and strontium-90 have half-lives of approximately 30 years. Meanwhile, plutonium has a half-life
