Principle of the scintillation detectors. Scintillates are one of the oldest types of radiation detector because measurements could be made with photographic film. If n=1.58 (typical for scintillator) then θ c = 39 degrees Then the fraction of light trapped is : f=1/2 (1- 1/n) = 0.18 Both scintillator and light guide are typically coated with aluminium foil to prevent leak of light, and then also by black tape to prevent outside light to leak in the detector III.

The photomultiplier tube (PMT) is normally supplied separately. CAUTION: DO NOT EXPOSE CRYSTAL TO ULTRAVIOLET RADIATION FROM FLUORESCENT background scintillation detector has become very useful. The time is drawing near for the NaI (Tl) scintillation detector to be used for industrial CT in addition to space physics, due to cost reductions, by using a small a multi-segmented structure.
