Is Iran’s Natanz nuclear facility facing radiation danger? IAEA boss sounds alarm over worst fears

The head of the International Atomic Energy Agency (IAEA), Rafael Mariano Grossi, warned on Monday that there is a potential risk of radiological and chemical contamination inside Iran's Natanz nuclear enrichment facility following recent Israeli airstrikes. However, radiation levels outside the facility remain normal, posing no immediate threat to the surrounding population or environment.

Speaking during an emergency session of the IAEA Board of Governors in Vienna—convened at Russia’s request to address Israel’s military actions targeting Iranian nuclear sites—Grossi stressed that while external radiation levels have not changed, there are serious concerns regarding internal exposure risks.

According to Grossi, uranium hexafluoride—a highly reactive and hazardous gas used during the uranium enrichment process—is present within the facility and could pose a serious health threat if inhaled or ingested. This substance, formed by combining uranium with fluorine, is known to be corrosive, capable of causing severe chemical burns, and potentially lethal when inhaled. He emphasized that while protective measures, such as respiratory equipment, can manage the danger effectively, the situation remains delicate.

“The radiation levels outside the Natanz site remain stable and within normal limits,” Grossi confirmed, adding that there is currently no indication of off-site contamination that could impact public health or the environment.
