Traces of the radioactive isotope cesium-137 exceeded the legal limit by 10 times.
The Italian Health Ministry carried out routine tests on wild boars in the Piedmont mountain area and discovered radioactive contamination in 27 boars.
According to Sina the Enea Radiation Protection Institute stated "the cesium-137 is an artificial radionuclide produced by nuclear fission, and is released from nuclear sites."
To Vima reported Italian Health Minister Renato Balntoutsi said teams of experts will try to solve the "mystery of cesium" by testing samples of water and soil in the area. Rabbits, hares and deer will also be tested for the presence of cesium.
Experts from the regional institution for environmental monitoring ARPA consider the most likely cause of the radioactive contamination is from Chernobyl.
