When the primary electron beam of a Scanning Electron Microscope (SEM) bombards a specimen, it causes the emission of secondary electrons from elements of the upper layer of the specimen (which are used to generate high-resolution images) and characteristic X-rays from the target (which can be used for elemental analysis of the specimen). Gamma rays are not typically emitted in this process.
