Used in the detection of gamma or neutron radiation. Consists of both a detector of incident radiation and a photomultiplier to produce countable pulses. The type of phosphor used as the detector is dependent on the type of radiation (i.e., gamma ray or neutron) to be detected. Gamma radiation produces scintillations in the phosphor as a result of photoelectric absorption, Compton scattering, or pair production, depending on the energy of the incident gamma. The intensity of the scintillation and the amplitude of the resulting pulse are proportional to the energy of the incident neutron or gamma ray. Scintillation detectors are efficient and can be made in small sizes. This results in high vertical resolution. Scintillation detectors are used in radioactivity logging, neutron logging, and pulsed neutron logging. See also photomultiplier.
