This student guide will help secondary students understand the random nature of radioactive decay, yet also figure out that it obeys patterns of predictability that can be measured in half-life. It was created by a PhET team member for use with "Alpha Decay".

Excellent multimedia resource to show the practical application of alpha decay processes in space exploration. The current fuel source for missions to Mars and beyond is Plutonium 238, which undergoes alpha decay.

An lesson plan for high school physics by a "Gold-Star" winning PhET team member, developed to accompany the simulation Alpha Decay. Requires a basic understanding of half-life and knowledge of the math underlying nuclear decay.

This online historical exhibit from the American Institute of Physics provides insight into the life and accomplishments of Marie Curie, whose pioneering work with radioactive materials led to two Nobel Prizes and the discovery of polonium and radium.
