INES directory

On this page you can browse the directory of reported nuclear and radiation incidents reported to the IAEA.

Please be aware that this directory is not complete, certainly not below INES-2, as different national regulatory bodies have different measures as to what to report to the IAEA and what not.

It is also possible to check a map with all reported the incidents.

To get notified of nuclear incidents as they are added to the directory, follow @ines_events on Twitter or through the RSS-feed.
