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 ...

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 ...

Bill Lee currently receives funding from the Welsh Government and the European Regional Development Fund for his Ser Cymru Chair at Bangor University. He has previously received BNFL, EPSRC and NDA ...

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 ...

Naturally occurring radioactive elements are substances whose atomic nuclei are unstable. To become stable, these nuclei spontaneously break down, or decay, by releasing energy in the form of ...
