Scintillators play an important role in radiation detection and imaging. Thallium-doped cesium iodide (CsI:Tl) sodium (NaI:Tl) are two of the major scintillators that have been used for many applications decades. In this paper, we will present improved scintillation performance Bridgman method-grown CsI(Tl) NaI(Tl) crystals developed by Xtallized Intelligence, Inc. (XI, Inc.), compare with comm...

The paper analyzes the problems that arise when assessing energy technical light output by existing methods. A modern alternative method for of various scintillators produced Institute Scintillation Materials National Academy Sciences Ukraine is described.
 possibility evaluating any scintillator relative comparison with a reference stilbene-based known shown. resulting ratio responses rec...

background: the natural radioactivity level and the radon concentration of soil were measured at four important geothermal area located in dikili geothermal region, turkey. materials and methods: the natural radionuclide content of soil samples were measured by nai(tl) gamma spectrometer system and the soil radon concentration were determined using kodak-pethe lr-115 type ii solid state nuclear...

In astroparticle, nuclear and subnuclear physics, low-counting experiments play an increasingly important role in the investigation of rare processes such as dark matter, double beta decay, some neutrino low-background spectrometry. Extremely features are more required to produce detectors apparata suitable sensitivity. Over time, a great deal interest attention developing experimental techniqu...

National Research Nuclear University, Moscow Engineering Physics Institute, Russia A full-body gamma-camera based on SiPM readout is currently under development as a part of MEPHI R activity supported in the framework of Russian Megagrants program. A goal of this development is a fast upgrade of existing medical equipment with minor changes in a system design and construction in order to combin...

Large NaI detectors are commonly used in gamma measurement systems where nuclide identification and quantification is desired. These systems are used to measure people, soil, drums, boxes, animals, and other things. For quantification, an efficiency calibration must be performed, which becomes increasingly difficult as the sources become large and complicated. Mathematical techniques can be qui...
