Nuclear policy specialist David Albright explains how his organization is monitoring for damage to nuclear sites following ...

There are three natural isotopes of uranium — uranium-234 (U-234), uranium-235 (U-235) and uranium-238 (U-238). U-238 is the most common one, accounting for around 99 per cent of natural uranium found ...

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

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

Although natural decay of U-235 means that this is unlikely to happen again, we humans have learned to take uranium ore and start a controlled fission process in reactors, beginning in the 1940s.

Late last week, Israel targeted three of Iran’s key nuclear facilities – Natanz, Isfahan and Fordo, killing several Iranian nuclear scientists. The facilities are heavily fortified and largely ...

ON bombarding uranium with neutrons, Fermi and collaborators1 found that at least four radioactive substances were produced, to two of which atomic numbers larger than 92 were ascribed. Further ...

Uranium is a radioactive element, meaning its atoms are unstable and decay over time, emitting ionizing radiation. This radiation can damage living tissues and DNA, leading to radiation sickness ...

Radon, a radioactive gas from decaying uranium, affects nearly 50% of Utah homes. Kerri Robbins, diagnosed with nonsmoking lung cancer, believes high radon levels contributed.

Uranium ore that miners dig up is relatively harmless. But it contains tiny amounts of a rare radioactive isotope, Uranium ...

Uranium (chemical symbol U) is a naturally occurring radioactive element. In its pure form it is a silver-coloured heavy metal, similar to lead, cadmium and tungsten. Like tungsten it is very dense, ...
