Radiation Threat and Health Risks from Israel's Strikes on Iran's Nuclear Program

Strategic Insights

— 2 min read

Israeli attacks on Iran's nuclear sites have raised concerns about the radiation threat and other health risks, but experts say the actual risk is minimal due to the low levels of radiation released during the strikes. While the European Union's nuclear watchdog, the International Atomic Energy Agency (IAEA), has detected no elevated radiation levels, the attacks have still caused significant damage to Iran's nuclear facilities, particularly at Natanz and Fordo.

Key Takeaways:

  • Radiation levels outside the Natanz complex remain normal, according to Rafael Grossi, chief of the IAEA.
  • The Fordo nuclear enrichment site is buried deep below a mountain, making it difficult to attack, but any potential radiation impact from a strike would be similar to the impact at Natanz.
  • Experts say the amount of uranium released during a strike would be unlikely to pose a risk to people near the facilities or in the wider region.
  • A person standing near an enrichment facility with a leak would likely be exposed to no more radiation than someone who took several trans-Atlantic flights.
  • The greater risk from any attack on nuclear enrichment sites might be from fluorine gas, which is extremely volatile and can be deadly if inhaled.
  • A French weapons assessment concluded that "it would take more than 1 gram of (uranium-238) to cause harm to a human being."
  • The AP's nuclear security coverage is supported by the Carnegie Corporation of New York and Outrider Foundation.
  • Israel's strikes on Iran's nuclear sites have destroyed centrifuges and caused significant damage to the Natanz and Fordo facilities.

Statistics:

  • 220 kilometers (135 miles) southeast of Tehran: The distance from Natanz to Tehran.
  • 100 kilometers (60 miles) southwest of Tehran: The distance from the Fordo site to the Shiite holy city of Qom.
  • 60 hours: The estimated time for a radiation leak to impact a population, "if it happens at all."
  • 1 gram: The amount of uranium-238 required to cause harm to a human being, according to a French weapons assessment.
  • 5% purity: The maximum level of uranium enrichment at the Natanz site before the Israeli strike.
  • 60% purity: The maximum level of uranium enrichment at the Natanz site after the Israeli strike.
  • 450 kilograms (1,000 pounds): The expected limit for the production of near-weapons grade uranium at the Fordo site.
  • $90 million: The amount reportedly wiped out from an Iranian cryptocurrency exchange.
