Types and Properties of Radiation

The video explains radiation, starting with atomic structure, where protons and neutrons form the nucleus and electrons orbit around it. It discusses isotopes, which are variations of elements with different neutron numbers, affecting nuclear stability. Unstable nuclei emit radiation, categorized into alpha, beta, and gamma types, each with distinct properties. Most radiation is natural, but humans have learned to produce it for various uses.
