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 ...

Brazil nuts are an especially nutrient-rich source of food: They contain important minerals like calcium and magnesium, essential amino acids and unsaturated fatty acids. Brazil nuts are characterized ...

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 ...

The standard should be, if Cesium-137 or other isotopes of concern are detectable in food items, they ought to be pulled off ...

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 ...

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 ...

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 ...

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 ...

Yes, bananas are radioactive — but so are Brazil nuts, carrots, potatoes, beer, peanut butter, and lima beans. In fact, the Earth is filled with radioactive matter, and we're exposed to an unavoidable ...

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 ...
