41. The scintillation process in inorganic materials is due to the electronic band structure found in the crystals. 42. Gamma rays given off from naturally occurring radioactive elements bombard the scintillation detector mounted on the tool. 43. A portion of the scintillation light propagates through the glass fiber, which acts as a waveguide. 44. The use of radiation detectors, such as Geiger counters and scintillation counter is one such method. 45. Optical fibers doped with a wavelength shifter are often used to collect scintillation light in particle detectors. 46. Over galactic distances, the interstellar medium induces some scintillation effects and artificial modulation of electromagnetic signals. 47. Electron recoils are produced by scintillation light produced in a CaWO 4 or ZnWO 4 absorber crystal. 48. But it's ?, so you need a scintillation counter not a Geiger-counter. 49. Charge and / or scintillation light produced in this way can be collected to produce a detected signal. 50. Pairs of photons in coincidence could be detected by the two scintillation detectors above and below the target.
