… 1986 at the nuclear power station in Chernobyl, Ukraine, dispersed radioactive cesium over large areas of Europe. The half life of 137Cs is 30 years and this radionuclide also behaves like potassium, which means that it can easily be taken up by the vegetation or be adsorbed in …
… their nests. This study focuses on the 137Cs activity in ant nests andthe cesium accumulation in these nests. The aims were (1) to estimate the 137Cs fall-out in1986, (2) estimate the radiation exposure of ants and (3) find how 137Cs is distributed in an anthill. Seven ant hills …
… of Sweden and deposited on the ground. The deposited radionu-clides, primarily cesium and iodine isotopes, were later absorbed into the soil and taken up by the roots of the plants. Some of these radionuclides, like 137Cs, still persist in some of the terrestrial ecosystems at …
… (Capreolus capreolus) och ren (Rangifer tarandus) fick förhöjda halter av Cesium-137, 137Cs, som i sin tur togs upp av de människor som åt av köttet. Upptaget i ekosystemet påverkas av flera faktorer; jordmånen och dess förmåga att binda radionukleider, växter och svamps …
Emissions of radionuclides to the atmosphere can lead to wet deposition on plants in the event of rainfall. An increased level of radioactivity in the plants may occur due to interception and retention of the radionuclides. If the content of the plants is above the threshold …

In April 1986 an accident occurred at the nuclear power station in Chernobyl. Radionuclides were spread all over Europe including Sweden. Today there are still measurable concentrations of 137Cs in the different ecosystems in the contaminated parts of Sweden. The wild boar is …
Gävlekvinnor minns Tjernobyl
… kan göra något åt vädret, så vi kunde inte göra något åt att det regnade ner cesium här. Regnet blev en budbärare för det farliga, det fanns med i alla minnen. Däremot försvann det farliga när snön kom. Har cancerfallen ökat i Gävleområdet? Nej, säger Strålsäkerhetsmyndigheten …
Several radioactive nuclides were deposited in Sweden after the Chernobyl accident in 1986. The greatest attention was given to 137Cs because of its relative long physical half life of about 30 years. 137Cs will be present in nature for more than 100 years before it has vanished …
