What is radioactivity and half-life? | Nuclear Physics | Visual Explanation

What is radioactivity? What is radioactive decay? What is half-life? This video is an introduction to nuclear physics and provides you with a concise overview of what radioactivity, radioactive decay and half-life 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. Half-life is the time it takes for the activity of the source to fall to half its original value.
