Properties of Gamma rays

  1. \gamma - rays are electromagnetic waves of short wavelength and high frequency. The wavelength of \gamma - rays range from 0.005 Angstrom to 0.5 Angstrom.
  2. They travel with velocity of light and are not charged particles like alpha or beta rays.
  3. They produce fluorescence effect on a photographic plate.
  4. They ionize gas they travel through but the ionization produced is very small.
  5. They are highly penetrating rays and they are even penetrative than alpha and beta particle. For instance, \gamma - rays can even pass through 30cm thick iron.
  6. \gamma - rays are not affected by electric or magnetic field.
  7. They are diffracted by crystals just like X-rays.
