Commentary: Damage at Iran nuclear sites and radiation risk explained

"News of the recent incidents at nuclear facilities in Iran have understandably raised concerns. Confirmed reports indicate that several facilities in Iran have been damaged, including sites in Tehran and Karaj that produce components for enrichment technology. The only reported damage to a site containing nuclear material is at the Natanz enrichment facility. There is no evidence of any release of radioactive material into the environment from the damage to this site.

“It is important to understand that radiation is easy to detect, even at very low levels, using well-established and highly sensitive monitoring equipment. No unusual levels have been reported.

“Uranium, used in enrichment, is both chemically and radiologically toxic, depending on enrichment level and isotopic makeup. It is only hazardous if inhaled or ingested; and the emitted radiation (mainly alpha particles) is stopped by a few centimetres of air. Any contamination present within the facility will be contained and managed using standard methods, such as isolating affected areas and controlling dust or particles.

“Radiation is a normal part of everyday life, found naturally in rocks, soil, the air, and even some foods. While the word ‘radioactive’ can sound alarming, it does not automatically mean danger.
