There was a recent recall of so-called ‘radioactive shrimp’ that were potentially contaminated with cesium-137 (Cs-137). But ...

These aren’t the places you’d expect to glow with danger, yet they do. Some are relics of the Cold War, others are industrial ...

In the icy bodies around our solar system, radiation emitted from rocky cores could break up water molecules and support hydrogen-eating microbes. To address this cosmic possibility, a team modeled a ...

A team of Italian researchers has uncovered compelling evidence of anomalous radioactive decay in cobalt-57 (Co-57) under ultrasonic stimulation, offering strong experimental support for the Deformed ...

When cells are exposed to ionizing radiation, more destructive chain reactions may occur than previously thought. An international team led by researchers has now observed intermolecular Coulombic ...

The Standard Model of physics, which explains the properties and interactions of the fundamental particles, does a phenomenal job with the things it gets right, and there's nothing that it obviously ...

An overly plump atomic nucleus just can’t keep itself together. When an atom has too many protons or neutrons, it’s inherently unstable. Although it might sit tight for a while, eventually it can’t ...

The nuclei of certain atoms are stable and under ordinary circumstances, stable nuclei do not undergo change. The nuclei of other atoms are unstable. These nuclei undergo change spontaneously, that is ...

Radioactivity figures large in the public consciousness in 2011, but many chemists may think it matters little to their work, if at all. Introductory chemistry classes taught us the names of the most ...

More than one hundred years ago, Henri Becquerel discovered that uranium emitted penetrating rays similar to those used by Wilhelm Röntgen to take the first X-ray image (of his wife’s hand), starting ...

One of the ways we measure the age of the Earth is using the half-life of uranium. With a half-life of around four billion years, your typical atom of uranium only has even odds of having decayed ...
