Amid rising fears of World War 3, experts have shared critical survival tips in the event of a nuclear strike. The International Commission on Radiological Protection (ICRP) warns, *“A nuclear detonation… may result in mass casualties,”* but survival is possible with the right actions.

If a blast occurs, you may have *“10 minutes or more to find an adequate shelter before fallout arrives.”* The safest option is to get inside a brick or concrete building or go underground—such as in basements or subways. The ICRP shares the example of Eizo Nomura, who survived Hiroshima’s bombing in 1945 because he was in a basement near ground zero.

Nuclear fallout—the radioactive dust after an explosion—can cause *“radiation sickness, cancer, and possibly death.”* Sheltering properly during those first minutes is key.

The urgency comes after the US bombed three major nuclear sites in Iran—Fordow, Natanz, and Esfahan. President Trump called the strikes a *“spectacular military success,”* but Iran’s foreign minister warned of *“everlasting consequences.”*

Experts believe Iran is close to developing nuclear weapons, with watchdog reports saying it could produce enough enriched uranium for several bombs *“in as little as two to three days.”*

Tensions remain dangerously high.
