Study Notes
Types of Radiation
- Alpha Particles (α) have a relative charge of +2 and exhibit a strong ionizing effect, but are not very penetrating, stopped by a thick sheet of paper, skin, or a few centimeters of air.
- Alpha Particles are deflected by magnetic and electric fields.
Beta Particles
- Beta Particles (β) have a relative charge of -1 and exhibit a weak ionizing effect, but are penetrating, stopped by a few millimeters of aluminum or other metal.
- Beta Particles are deflected by magnetic and electric fields.
Gamma Rays
- Gamma Rays (γ) have no charge and exhibit a very weak ionizing effect, but are highly penetrating, never completely stopped, though lead and thick concrete will reduce intensity.
- Gamma Rays are not deflected by magnetic or electric fields.
