The scintillation detector comprises of NaI (Tl) crystal (scintillator) fixed tightly on a photomultiplier tube in a Gamma Ray spectrometer. For detection and measurement of gamma rays one inch or more thick scintillator in used. WebHowever, astronomers can still find them and learn a lot about them. They do this by measuring the visible light, X-rays and radio waves emitted by material in the immediate environment of a black hole. For example, when a normal star orbits around a black hole we can measure the speed of the star by studying the visible light that it emits.
