Destroying Iran's stores of enriched uranium would bring danger for people nearby but not trigger another Chernobyl.

When an atom breaks apart, it gives out energy and more neutrons, which can then split other atoms. Get enough atoms splitting and you have the chain reaction needed for a bomb blast ...

"When you dig uranium out of the ground, it comes in two forms: 99.3% is uranium-238 - and 0.7%, or about one atom in 150, is uranium-235, and this is what you need to work in your nuclear reactor ...

On June 9, four days before Israel struck Iran’s nuclear facilities, the Board of Governors of the International Atomic ...

Uranium enrichment sites are used to build up supplies of a particular type - or isotope - of uranium. "When you dig uranium out of the ground, it comes in two forms: 99.3% is uranium-238 - and 0.7%, ...

Bombing Iran’s nuclear infrastructure may not spark a nuclear detonation—but that doesn’t make it safe. In recent weeks, Israel has ...

Far more dangerous than U-235 are the elemental products given off when nuclear fuel goes through fission—especially iodine, ...

For human health, the higher the level of U-235 enrichment, the greater the danger. The isotope and its decay products emit three types of radiation: alpha particles, beta particles and gamma rays.

By itself, the enriched U-235 isotope is something of “a damp squib,” says Paddy Regan, a nuclear physics professor at the U.K.’s University of Surrey. “Uranium itself is not particularly ...

In the coming days or hours he will determine whether to join the effort and help Israel destroy the Fordow reactor, located 90 meters below ground, the stronghold completing the production of nuclear ...
