Since the release of the information notes on April 7, 15 and 17, 2020, the number of fires in Ukraine has decreased. As of April 24, 2020, however, a few outbursts remain in the exclusion zone around the Chernobyl power plant.
IRSN new information report updates the previous situation points by setting out the state of the fires to date and by updating trajectories of the fire-contaminated air masses.
As promised, IRSN publishes the results of its first measurements, which notably concern the airborne 137Cs activity in France of 137Cs-labeled air masses from the fire area. These measurements show very tiny levels of radioactivity, consistent with its modeling results.
