What’s going on with this silent threat that can stealthily damage your body in ways that can take years to reveal themselves ...

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 ...

Radioactive decay is a fundamental process in nature by which an unstable atomic nucleus loses energy by radiation. Studying nuclear decay modes is crucial for understanding properties of atomic ...

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 ...

In this lesson, students will investigate the nature of radioactivity and the effect of both distance and shielding materials on different radioactive sources using a Geiger-Muller tube with a counter ...
