Chapter 33: The Atomic Nucleus and Radioactivity
... How does the source differ for a beam of gamma rays and a beam of X rays. Ans. Gamma rays come from the nuclei of some atoms. X rays come from the reconfiguration of electrons surrounding the nucleus of an atom. They may also be produced when an electron undergoes a large acceleration. ...
