Chernobyl1,100 hectares are burning inside the exclusion zone after a drone crash.
Burning radioactive biomass aerosolizes contaminated particles; landmines from Russia’s 2022 incursion block firefighters from parts of the zone.
Ukraine’s emergency service reports gamma within normal limits; Russian drones continue igniting border-zone forests.

THE ZONE
After the April 1986 reactor No. 4 explosion, Soviet authorities evacuated a 30-km radius around the plant — roughly 2,600 km² spanning Ukraine and Belarus. Forty years later it remains one of the most contaminated landscapes on Earth, and one of Europe's largest involuntary nature reserves.
WHY FIRE IS THE PROBLEM
Cesium-137 and strontium-90 from the 1986 fallout were absorbed by trees, leaf litter, and topsoil. Burning that biomass re-aerosolizes the radionuclides — a wildfire effectively re-releases a fraction of the original accident as smoke, distributing it on the wind.
THE RED FOREST
The pine stand directly downwind of reactor No. 4 absorbed the heaviest fallout and turned rust-red as the trees died. Soviet workers bulldozed and buried much of it in 1986, but the remaining forest floor is the single most radioactive open-air area in the zone — and the most flammable.
THE 2020 PRECEDENT
In April 2020, fires burned roughly 11,500 hectares inside the zone — the worst on record at the time. Monitoring stations in Kyiv, 100 km south, registered elevated cesium-137 in the air column for days. The plume was tracked as far as Scandinavia before dispersing below detection thresholds.
THE MINEFIELD COMPLICATION
Russian forces occupied the plant and zone from February to March 2022, digging trenches in the Red Forest's contaminated soil and laying mines along withdrawal routes. Ukrainian firefighters now face a layered hazard — radiation, unexploded ordnance, and active drone activity — that no fire service is equipped to handle as a routine response.
THE QUIZ
The contamination half-lives drive how long the zone stays dangerous, but the headline isotopes have a quirk worth knowing.
