What is radioactivity? What is radioactive decay? What is halflife? This video is an introduction to nuclear physics and provides you with a concise overview of what radioactivity, radioactive decay and halflife is.

Summary:
1. Radioactivity is the act of emitting radiation spontaneously and randomly.
2. Radioactive decay is the emission of energy in the form of ionizing radiation.
3. Halflife is the time it takes for the activity of the source to fall to half its original value.
