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 ...

Both radioisotopes and enriched stable isotopes are essential to a wide variety of applications in medicine, where they are used in the diagnosis and treatment of illnesses. This report focuses ...

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 ...

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 ...

Computer rendering of the experimental setup to detect decay signatures of isotopes. A beam of excited sodium-32 nuclei implants and decays in the Facility for Rare Isotope Beams Decay Station ...
