Researchers measured very precisely atomic masses of radioactive lanthanum isotopes and found an interesting feature in their nuclear binding energies. The discovery provides essential data for ...

Project Omega, started with the help of former NRC Chair Chris Hanson, wants to convert radiation from isotopes into electricity.

Add Yahoo as a preferred source to see more of our stories on Google. The new BetaVolt battery beside a small coin. The battery is smaller in size in comparison. Chinese scientists have built a ...

A South African university launched an anti-poaching campaign Thursday to inject the horns of rhinos with radioactive isotopes that it says are harmless for the animals but can be detected by customs ...

Astatine is one of the least-studied elements of the periodic table, because all isotopes of astatine are unstable, with the longest half-life barely exceeding 8 hours. Thus, only radiochemists at the ...

In this lesson, students will investigate the nature of radioactivity and the effect of both distance and shielding materials on different radioactive sources using a Geiger-Muller tube with a counter ...

MOKOPANE, South Africa (AP) -- A South African university launched an anti-poaching campaign Thursday to inject the horns of rhinos with radioactive isotopes that it says are harmless for the animals ...

When the Chernobyl nuclear reactor exploded in 1986, scientists expected the surrounding land to remain uninhabitable for centuries. The accident released large amounts of radioactive material into ...

Antarctica's ice sheets are still releasing radioactive chlorine from marine nuclear weapons tests in the 1950s, a new study finds. This suggests regions in Antarctica store and vent the radioactive ...
