Scientists have identified traces of radioactive stardust preserved in Antarctic ice, directly linking Earth to debris ...

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 ...

Earth is currently passing through a cloud of radioactive debris from an ancient supernova. Traces of iron-60, an isotope ...

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 ...

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 ...

You can hold plutonium in your hand, but it has the potential to destroy entire cities. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Plutonium ...

What do a capsule in Australia, a cylinder in Thailand and a camera in the US have in common? All three contained radioactive material and went missing over the past three months, in what experts say ...

Cosmogenic beryllium isotopes, chiefly 10Be and its stable counterpart 9Be, have become indispensable tracers for quantifying rates and pathways of Earth surface processes. Produced by the interaction ...

Nuclear blasts create dangerous fallout — residual radioactive material that travels high into the air, cools into dust, and eventually settles back to the ground, poisoning it in the process. Most ...
