Gamma ray appearance
WebFeb 4, 2024 · Gamma rays are produced from excited nuclei of a radionuclide as it undergoes radioactive decay, while X-rays are produced by the deceleration of electrons … WebTABLE OF CONTENTS. Alpha and beta radiation are types of particle radiation, while gamma radiation is a type of electromagnetic radiation. The breaking of an atom produces alpha and beta particle radiation. The movement of electrical charges causes gamma radiation. Let’s look at each type of radiation in more detail.
