Among the many science toys that have fallen out of fashion since we started getting nervous around things like mercury, ...

For the first time, researchers have directly observed an exotic type of radioactive decay called two-neutrino double electron capture. The decay, seen in xenon-124 atoms, happens so sparingly that it ...

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 ...

In this video excerpt from NOVA's "Hunting the Elements," New York Times technology columnist David Pogue explores how isotopes of carbon can be used to determine the age of once-living matter. Learn ...

Radioactive material gets a bad rap, what with radiation and fallout and nuclear waste and all. But it offers some practical uses. One of the coolest (OK, maybe the coolest) is using radioactive ...

The questions in this quiz are suitable for GCSE physics students studying stable nuclei, nuclear radiation, half life and nuclear equations. If you struggled with the quiz, don't panic - we've got ...

Geodynamics, Neutrino Oscillation-Induced Radioactive Decay, Magmatic Activity, Earthquake Mechanism, Earthquake Precursor ...

The first direct detection of radioactive titanium associated with supernova remnant 1987A has been made by ESA’s Integral space observatory. The radioactive decay has likely been powering the glowing ...

About 50% of the heat given off by the Earth is generated by the radioactive decay of elements such as uranium and thorium, and their decay products. That is the conclusion of an international team of ...

Radioactive elements on Earth are like geological watches. A radioactive isotope of carbon is used to date human civilizations, among other things, because we know that its half-life is precisely ...
