IRSN has performed a modeling estimation of the amount of radioactivity re-emitted by fires, and a modeling of the plume dispersion over Europe.
The radioactive release used was evaluated by reverse modeling (use of available measurements) over the period from April 3 to 12, 2020, the dispersion simulation continues until April 14, 2020.
