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 ...

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.

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 ...

A new experiment using rare-isotope beams has provided new insight into the origin of proton-rich isotopes known as p-nuclei.

Actinium-225 is an alpha emitter, spewing out tiny bundles of energy that promise to kill cancer cells, but only at short range. This isotope and others like it are the focus of a ...

Kyle Clavier, left, and Dan Clayton are helping develop a standardized screening method to determine the most important radioactive isotopes to monitor from all of those produced by an advanced ...
