Following are the three types of radiation that are commonly observed:
- Alpha radiation: This radiation is heavy, consist of very short-range particles and are ejected by the Helium nucleus. This radiation cannot penetrate through human skin. Uranium is an example of alpha radiation.
- Beta radiation: The particles in beta radiation are short-range and light-weighted. These radiations are ejected electrons. protection is provided with the help of clothing. Sulfur-35 is an example of beta radiation.
- Gamma radiation: This is a highly penetrating electromagnetic radiation.
