You do know that X-Rays and Gamma rays are essentially the same thing?

They occupy much the same part of the EM spectrum. The distinction
often made between them is to do with their means of production. Gamma
rays are produced inside the atomic nucleus while X-Rays are created by
relaxation of highly excited electrons outside the nucleus.
