`gamma-rays` radiation can be used to create electron-positron pair. In this process of pair production. `gamma-rays` energy cannot be less than.

gamma -rays can be best detected with

To produce an electron-position pair, the minimum energy of gamma -ray photon must be

A gamma ray photon creates an electron positron pair. If the rest mass energy of an electron is 0.5 MeV and the total kinetic energy of the electron positron pair is 0.78 MeV, then the energy of the gamma ray photon must be

Gamma rays are used in the treatment of ____.
