in how many ways can gamma rays produce ionization of the atoms? explain

Question

anonymous · Answer

gamma rays can eject electrons from atoms

ujjwal · Answer

gamma ray being an electromagnetic radiation consists of photons energy given by $$E=h \nu$$ where h is plank's constant and 
nu is frequency of radiation 
these energetic photons collide with electrons and if the energy of photon is greater than or equal to ionisation potential of atom, the photon eventually ejects the electron from the atom... thus ionising the atom...

The mechanisms of interaction for ionizing radiation in the form of x-rays and gamma-rays include the photoelectric effect, Compton scattering and at high enough energies, electron positron pair production.
