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 ...

The standard should be, if Cesium-137 or other isotopes of concern are detectable in food items, they ought to be pulled off shelves, or at the very least labeled with warnings so consumers can make ...

The Rhisotope Project is embedding radioactive isotopes in the horns of rhinos in an effort to prevent poaching. Rhinos previously injected with the isotopes during Rhisotope's test phase turned out ...

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 ...

The current state of radiotherapeutics is “the isotope wars”, according to Jack Hoppin, CEO of Boston’s Ratio Therapeutics.

MOKOPANE, South Africa — 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 ...

There was a recent recall of so-called ‘radioactive shrimp’ that were potentially contaminated with cesium-137 (Cs-137). But contamination isn’t an all-or-nothing affair, so you might wonder exactly ...
