The material of a PMT is usually glass. Glass has an intrinsic amount of 40K which contributes to the radiological background of the scintillation detector. 40K emits gamma rays at 1461 keV and β-particles. The face-plate of the PMT can be constructed of special low-K glass. Sodium Iodide crystals are the most widely available scintillation detector today. It has a variety of uses from Isotopic identification to medical gamma cameras.

Scintillation 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). Besides a wide range of standard scintillation detectors we supply an extensive variety of tailor-made scintillation detectors to the specifications of the end-user. All known and generally available scintillation materials are employed ranging from plastic scintillators and liquid scintillators to inorganic crystals like NaI(Tl) , CsI(Tl Scintillation materials and detectors that are used in many applications, such as medical imaging, security, oil-logging, high energy physics and non-destructive inspection, are reviewed.

Borexino: the boron experiment Up to now, the Borexino detector is the only scintillation experiment used to detect solar neutrinos. Its target material is based on  Laboratoriet ska alltid utprova relevant kontrollmaterial.

In particular, optical and luminescence characteristics were analysed of doped heavyoxide single-crystal films Lu 3 Al 5 O 12 on undoped Y 3 Al 5 O 12 substrate for high-resolution X-ray screens. Interaction of radiation with absorbing material, Scintillation detector About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new Scintillation was introduced in the beginning of the 20 th century but gained popularity when the photomultiplier tube (PMT) was introduced and improved as a scintillation counter in the 1940 and 50s [12]. The PMT has been the main choice for photon detection ever since due to the fact Figure 1: Schematic diagram of a scintillation detector comprising a scintillation material coupled to a photomultiplier tube.

Scintillators work by converting X-ray energy into visible light. The energy of the incoming X-ray is completely absorbed by the material,  Scintillation materials. Luminescent materials: reemit part of the absorbed energy in the form of light. Emissions: fluorescence (prompt), delayed fluorescence.
