IAEA has reported “no increase in off-site radiation levels” after the latest strikes on 22 June 2025 on the three Iranian nuclear sites at Fordow, Esfahan and Natanz.
Based on available information, the International Atomic Energy Agency (IAEA) has confirmed “no off-site radiation increase” from three Iranian nuclear sites of Fordow, Natanz and Esfahan following recent aerial strikes.
The IAEA assessed that the latest strike in the early morning on 22 June 2025 has led to extensive additional damage at Esfahan site, which had already struck several times since the conflict started on 13 June 2025. Several buildings at the Esfahan complex were damaged, some of which may have contained nuclear material. Also, entrances to tunnels used for the storage of enriched material appear to have been hit.
The Fordow site is directly impacted. It has visible craters indicative of use of ground-penetrating munitions. Fordow is Iran’s main location for enriching uranium at 60%. The degree of damage inside the uranium enrichment halls could not be immediately assessed because the facility is built deep inside a mountain. Given the type of munition used, and the extreme vibration-sensitive nature of centrifuges, very significant damage is expected to have occurred.
The Fuel Enrichment Plant at Natanz, which was damaged extensively earlier, was again hit with ground-penetrating munitions.
The IAEA has called for ending the hostilities so that it could resume verification activities, including of stockpile of more than 400 kg of highly enriched uranium at the sites, which it last verified few days before the conflict began.
