n view of the situation in Ukraine, IRSN has produced an information note presenting the nuclear facilities in Ukraine and an overview on the radiological monitoring of the country.​ An increase of the radiological atmosphere around the Chernobyl site was reportedly observed on the stations near the installations. The Ukrainian safety authority mentions a resuspension of contamination by the passage of military tanks. ​IRSN does not have any information to confirm or refute this information. It is advisable to remain very cautious about these measurements at this stage. No increase in radioactivity has been detected in the European countries with which IRSN is in contact.
