In April 2020, wildfires were reported in the exclusion zone around the damaged Chernobyl nuclear reactor. The fires reached the red forest, one of the most contaminated natural environments , and came as close as two kilometers from the sarcophagi covering the damaged reactor. These are not the first wildfires after the 1986 accident and radiation scientists have recognized the potential to return radioactive material into the air, especially cesium-137 and strontium-90. This poses an obvious and immediate health risk to fire fighters, but smoke plumes may also transport this re-suspended radioactive material over long distances, resulting in redistribution of the historic fall-out from the accident.
