An international consortium of scientists has specified a map of concentrations of cesium and plutonium radionuclides in soils in Switzerland and several neighboring countries. Using an archive of European soil samples, a team of researchers led by Catherine Meisburger from the University of Basel was able to track down the sources of radioactive fallout between 1960 and 2009. This study was published in the journal Scientific Reports. On the new map of radioactive contamination of the soil, there are not only Switzerland but also several neighboring countries – France, Italy, Germany and Belgium. The map is based on a new calculation method, namely the use of the ratio of cesium to plutonium. These two radionuclides were released during military nuclear tests in the 1960s. Additional cesium fell into some countries during the Chernobyl accident in 1986.
