Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A ...

Nuclear energy is great because it doesn't produce any harmful emissions, but the waste it does produce can stick around for ...

On April 7, a process 20 years in the making began. The U.S. Army Corps of Engineers started excavation at a Parks Township nuclear waste site. This isn’t like other abandoned industrial sites. In ...

Scientists have gained insights into the weak nuclear force from new, more sensitive studies of the beta decays of the 'mirror' nuclei lithium-8 and boron-8. The weak nuclear force drives the process ...

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 ...

Alpha decay represents a fundamental mode of radioactive disintegration wherein an unstable nucleus emits an alpha particle—a tightly bound cluster of two protons and two neutrons. This process not ...

Researchers have found that titanium-48 changes from a shell model structure to an alpha-cluster structure depending on the distance from the center of the nucleus. The results upend the conventional ...
