Chernobyl radiation still found in Finnish mushrooms

Radioactive fallout from the 1986 Chernobyl nuclear disaster remains detectable in mushrooms across Finland, although levels have declined over time, according to a new nationwide study by the Radiation and Nuclear Safety Authority. The findings are based on a large dataset collected with the help of mushroom pickers, who submitted 875 samples during the 2025 harvesting season. The samples covered 187 municipalities and included 60 different species.
