In physics terms, radiation is simply energy on the move, carried by waves like sunlight or particles like those released by ...

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a new and faster method for ...

Radioactive decay is the strange and almost mystical ability for one element to naturally and spontaneously transmute into another. In the process, those elements tend to emit deadly forms of ...

Scientists have developed a supercooled sensor that delivers full radioactivity profiles without chemical tracers.

A number of technologies are predicated on the assumption that rates of radioactive decay are constant -- but what if they aren't?

A radioactive isotope's nucleus is unstable and spontaneously decays, giving off radiation and changing into a different isotope. The rate at which nuclei decay is constant.

A chart purportedly showing radioactive water seeping into the ocean from the Fukushima nuclear plant actually depicts something else.

GCSE CCEA Double Award Radioactive decay and half-life - CCEA Half-life Radioactivity was first noticed by French physicist, Henri Becquerel, in 1896, when he observed that some photographic ...

On the periodic table, most elements have at least one stable form. But others have only unstable forms, all of which decay by emitting radiation and transforming into different elements until ...

This strange new battery, developed by scientists from the UKAEA and Britain's University of Bristol, works by using the radioactive decay of the carbon-14 isotope contained within a diamond.

This new diamond battery acts like a kind of solar panel, but instead of soaking in light, it captures fast-moving electrons from the radioactive decay of carbon-14.

The "Gilbert U-238 Atomic Energy Laboratory" contains four real and radioactive uranium ores for kids to experiment with.
