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 ...

One year ago last week the Clinton Laboratories at Oak Ridge, Tenn. began selling radioactive isotopes made in its uranium pile. Already, these atomic by-products have had important influences on U.S.

In this lesson, students will simulate the randomness of decay in radioactive atoms and visualize the half-life of a sample radioactive element. This lesson can be completed in two (2) 45-minute class ...

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 ...
