​Since the publication of our information report of April 24, 2020, it seems that the fire outbreaks are now extinct. The new information report published today by IRSN contains the latest information available and updates the modeling of the trajectories of air masses contaminated by fires.

​The new information note published today by IRSN updates our previous situation points. It also gives the results of the first measurements carried out in France concerning air masses from the fire area. These measurements show very tiny levels of radioactivity, consistent with its modeling results.

The fires in Ukraine, which had been announced extinguished on April 15, 2020, were reactivated under the effect of strong winds which stirred up the embers of previous fires.

On April 17, 2020, IRSN produced a new information report explaining the evolution of the fires compared to the situation presented on April 15, 2020, and specifying some elements relating to the nuclear installations located on the site of the Chernobyl NPP.

​IRSN publishes an assessment of the possible radiological impacts of the fires in Ukraine in the exclusion zone around the Chernobyl power plant.

​An earthquake occurred on November 11, 2019 in the Ardèche region in Le Teil municipality at approximately 10 km to the west of the city Montelimar. The ground motion lasted several seconds in the vicinity of the epicenter and was felt by the population in the south-east of France, particularly up in Saint-Etienne, Grenoble, Lyon, Montpellier and Marseille.

IRSN and CEA presented their research activities in radiobiology, radiopathology, epidemiology and dosimetry in a tripartite seminar organized on 28-29 October 2019 by the QST-NIRS in Chiba, Japan.

Synthesis of all radiological environmental characterization data collected by the members of the National Measurement Network (RNM), the 2015-2017 report is available
