Radiation Threat and Health Risks from Iran's Nuclear Facilities After US Strikes

Strategic Insights

— 2 min read

The US launched a series of airstrikes targeting Iran's nuclear facilities, sparking concerns about the potential for radiation and health risks. According to the International Atomic Energy Agency (IAEA), no increase in off-site radiation levels has been reported, but experts warn of potential chemical hazards and radiation risks, particularly from fluorine gas. The IAEA is calling for inspectors to be allowed to assess the damage to the sites.

Key Takeaways:

  • Iran enriches uranium to up to 60% purity at the Natanz facility, a mildly radioactive level and a short step away from weapons-grade material.
  • The IAEA believes that most if not all of the centrifuges at Natanz were destroyed by an Israeli strike, which may have led to radiological and chemical contamination inside the facility.
  • Radiation levels outside the Natanz complex remain normal, according to Rafael Grossi, chief of the IAEA.
  • The Fordo nuclear enrichment site, buried deep below a mountain, is difficult to attack and is considered a high-value target by the Israelis.
  • Experts say that any potential radiation impact from a strike on Fordo would be similar to the impact at Natanz, with manageable levels of radiation that could be mitigated with protective gear.
  • Israel previously struck four buildings at the Isfahan nuclear site, but the IAEA has reported no sign of increased radiation.
  • Fluorine gas, mixed with uranium to create uranium hexafluoride, is a greater concern than radiation due to its volatility and potential for inhalation.
  • A far greater concern is the potential attack on Iran's only commercial nuclear power plant, the Bushehr, which remains radioactive for thousands of years.

Statistics:

  • The Natanz facility has been enriching uranium to up to 5% purity.
  • 220 kilometers (135 miles) separates Natanz from Tehran.
  • The Fordo nuclear enrichment site is buried 100 kilometers (60 miles) southwest of Tehran.
  • The Bushehr nuclear power plant is located 750 kilometers (465 miles) south of Tehran.
  • No increase in off-site radiation levels has been reported by the IAEA.
  • The amount of uranium released in strikes is unlikely to pose a risk to people near the facilities or in the wider region.
