There are several types of mushrooms in Finland these days which are still affected by the Chernobyl nuclear meltdown incident. These mushrooms are still radioactive even 23 years since the Ukrainian power plant incident. The EU states that mushrooms should not contain more than 600 Becquerels (bq) of radiation per kg. According to SikuNews, the highest levels of radiation concentration in Finland after the Chernobyl disaster were in Pirkanmaa, Häme, and the Kymi Valley.
