This module (Nuclear Physics) introduces the basic properties of the atomic nucleus nuclear constituents; the binding energy; isotopes; and nuclear models are concepts dealt in the first activity. Most atoms found in nature are stable and do not emit particles or energy that change form over time. Heavy elements, such as uranium or thorium, and their decay chain elements do not have stable nuclei. They emit radiation in their naturally occurring state. The second activity of the module dwells on radioactivity and related applications. The third activity is on the interaction of nuclear radiation. The study of interaction of radiation with matter is the basis for radiation detection and measurement. Most applications of radiation require the knowledge of interaction of radiation with matter. One needs to know elementary particles and their interaction to gain a more unified understanding of nuclear forces and to achieve greater predictive power. Activity four is a survey of elementary particles and theories that explain nuclear interaction in terms of elementary particles.
