Mushrooms foraged in Sweden could help research Chernobyl radioactive fallout

Sweden's strong foraging culture could help determine how much radioactive fallout remains in the Scandinavian country, 38 years after the Chernobyl nuclear explosion.
Sweden's strong foraging culture could help determine how much radioactive fallout remains in the Scandinavian country, 38 years after the Chernobyl nuclear explosion.
The Swedish Radiation Safety Authority has asked mushroom-pickers to send samples of this season's harvest for testing. The goal of the measurement project is to map the levels of Cesium-137 in mushrooms and see how much remains after the April 26, 1986 disaster at the Soviet nuclear power plant in what is now Ukraine.
Cesium, the key radioactive material released in the fallout, has a half-life of some 30 years. It can build up in the body, and high levels are thought to be a risk.
The radiation watchdog is counting on the foraging lifestyle in Sweden, which is covered by more than 60 per cent of forest, to aid its research. In late summer, many Swedes spend days in the woods collecting berries, mushrooms and plants.
It's asking foragers for details of where they found their bounty — though they don't have to disclose the whereabouts of the prized golden chanterelle mushroom.
Spots that regularly produce such chanterelles — often called “the gold of the forest mushroom” — are closely guarded family secrets that could cause headaches for researchers who need data points.
“It doesn’t have to be the exact location of the most secret chanterelle spot,” said Pål Andersson, an investigator at the Radiation Safety Authority.
