Scintillation detector

Principle of operation. A scintillation detector or scintillation counter is obtained when a scintillator is coupled to an electronic light sensor such as a photomultiplier tube (PMT), photodiode, or silicon photomultiplier.PMTs absorb the light emitted by the scintillator and re-emit it in the form of electrons via the photoelectric effect PETER B. VOSE, in Introduction to Nuclear Techniques in Agronomy and Plant Biology, 1980. Detector Systems for Scintillation Counting. A scintillation detector consists of a crystal or other phosphor coupled with its mount to a PM tube with a silicone oil light-couple. The oil light-couple is necessary to obtain an intimate connection of the phosphor with the photomultiplier to ensure the.

The scintillation detector was possibly the first radiation detector discovered. You might have heard the story of the discovery of X-rays by Wilhelm Roentgen in 1895. He was working one evening in his laboratory in Wurzburg, Germany with a device which fired a beam of electrons at a target inside an evacuated glass tube Syed Naeem Ahmed, in Physics and Engineering of Radiation Detection (Second Edition), 2015. 6.1.E Density and atomic weight. Scintillation detectors are used to detect all types of radiation, including γ-rays, electrons, neutrons, α-particles, and neutrinos. Efficient detection of these particles depends on how well and how quickly they lose energy in the scintillation medium Scintillation, which occurs in the NaI(Tl) crystal, is a flash of light produced in a transparent material by the passage of a particle (an electron, an alpha particle, an ion, or a high-energy photon).

The scintillation process now results in the emission of visible light that can be detected by an appropriate photo-detector at room temperature. Such a scintillation process is often referred to as luminescence. The scintillation photons produced by luminescence are emitted isotropically from the point of interaction The scintillation detector was originally developed, as we know it today, in the 1950's and 60's to solve the issue of low efficiency rates that the gas filled detectors had.
