SUMMARY
The upper energy limit of gamma rays is not defined, as it is fundamentally a question of physical possibility. Gamma rays typically range from some MeV to 50 MeV, with the distinction from hard X-rays based on their origin; gamma rays arise from nuclear decays while hard X-rays are produced by electronic devices. The GZK cutoff represents a practical limit on the energy of gamma rays that can traverse vast distances in the universe without being attenuated.
