Researchers Model Changes in Radiation Distribution Over Eastern Europe Due to Fires

Researchers from the University of South Carolina in Columbia used satellite imagery of fires in the 2000s and field measurements of radioisotope levels to model changes in the distribution of radiation over the region. The researchers found that fires likely spread radiation across much of Eastern Europe, with Ukraine, Belarus and Russia receiving the highest doses. Traces of radioactive cesium-137 may have even traveled to Turkey, Italy and Scandinavia.

Previously, the same researchers had found that reduced microbial activity in the area leads to slower than expected rates of decomposition of dead plant matter, leading to a build-up of leaf litter and plant debris on the forest floor — providing more fuel for forest fires. Under climate models that predict a hotter, drier Eastern Europe in the future, such forest fires could become more frequent, the researchers concluded.
