<Li> In a recently published study scientists from Forschungszentrum Jülich, Germany, published the "Korma - Report" with data of radiological long - term measurements that were performed between 1998 and 2007 in a region in Belarus that was affected by the Chernobyl accident . The internal radiation exposure of the inhabitants in a village in Korma County / Belarus caused by the existing radioactive contamination has experienced a significant decrease from a very high level . The external exposure, however, reveals a different picture . Although an overall decrease was observed, the organic constituents of the soil show an increase in contamination . This increase was not observed in soils from cultivated land or gardens . According to the Korma Report the internal dose will decrease to less than 0.2 mSv / a in 2011 and to below 0.1 mSv / a in 2020 . Despite this, the cumulative dose will remain significantly higher than "normal" values due to external exposure . Resettlement may even be possible in former prohibited areas provided that people comply with appropriate dietary rules . </Li> <Li> Study of heightened mortality in Sweden . But it must be pointed out that this study, and in particular the conclusions drawn has been very criticized . </Li> <Li> One study reports increased levels of birth defects in Germany and Finland in the wake of the accident . </Li> <Li> A change in the human sex ratio at birth from 1987 onward in several European countries has been linked to Chernobyl fallout . </Li>
