Input: It's not Cherenkov radiation, but this type of radiation is faintly visible to observers who are accustomed to a darkened room as a blue glow seeming to originate within the eye. This type of radiation is emitted when an electron in copper transitions from the L shell to the K shell, in a process which is used to provide a source in crystallography. This type of radiation was inelastically scattered by electrons in the first observation of the Compton Effect. Sometimes known as Rontgen radiation, for 10 points, name this type of electromagnetic radiation whose wavelength lies between UV and gamma rays.
