Model CEBRS-1.5x1.5 Cerium Bromide Scintillation Detector is a high-efficiency scintillation detector featuring a 1.5x1.5 in. The scintillation counter quantifies the resulting flashes of light. Scintillation detectors are usually water clear crystalline materials and work better if they contain heavy elements, which are more likely to intercept a gamma ray within the material and absorb its energy. 1. Energy range. The perfect scintillator should be dense, bright and fast. 1 in. In that time we have built an industry-leading portfolio of products and product knowledge, of bespoke scintillation detector designs and scintillation material applications. Used with Ludlum General Purpose Radiation Survey Meters, Ratemeters, Scalers. 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). Scintillation Detectors. The voltage depends on the type of photomultiplier tube that is used in the system and may vary from about 1,000 volts to about 3,000 volts. The scintillator of the claimed scintillation detector is formed from pixels (2), which are separated from each other by interstices (4). Scintillation Detectors Scintillators - General Characteristics Sensitivity to energy Fast time response Pulse shape discrimination Main Features: High efficiency for conversion of exciting energy to fluorescent radiation Transparency to its fluorescent radiation to allow transmission of light The most common applications of scintillation detectors are medical imaging (PET, X-ray CT, SPECT), 9) security, 10) oil-logging, 11) non-destructive studies of cultural objects, 12) astro-physics 13) and particle-physics.
