What is the difference between X-rays and Gamma rays?: (A) X-rays are produced extranuclearly whereas gamma rays are produced in nuclear decays, (B) X-rays have higher energies than gamma rays, (C) Gamma rays are produced by bremsstrahlung, (D) X-rays and gamma rays interact with matter differently
Answer is A. X rays are produced when accelerated electrons strike heavy metal nucleus and are deflected with deceleration. Gamma rays are produced intranuclearly to stabilize nucleus of the radioactive element.Reference: Khan Physics of Radiation therapy; 5th edition
