What is the difference between γ rays and characteristic x rays? Is either necessarily more energetic than the other? Which can be the most energetic?
Gamma rays as being photons having energies that are characteristic of nuclear transitions, since they were produced by nuclear transitions.while X-rays as photons having energies that are characteristic of transitions involving deeply bound atomic electrons, since they were produced by such transitions.
roughly X-rays would have energies in the range 1 keV to 100 keV, while gamma-rays would have energies of about 1 MeV and above.
