A systematic study of the attenuation electromagnetic radiation in Nuclear Track Detectors (NTDs) is carried out. The gamma-ray, X-ray, UV, visible, and infrared NTDs are investigated using NaI(Tl) detector, Gas Electron Multiplier (GEM) UV-Vis spectrophotometer, FTIR spectrophotometer respectively. values some important parameters (e.g., optical depth, coefficient, etc.) three commercially ava...

Abstract Thallium-activated sodium iodide (NaI(Tl)) detectors can be used in gamma cameras, environmental radiation assessments, including emission levels from nuclear reactors, and analysis equipment. This three-phase investigation aimed to model a standard NaI(Tl) detector using the Monte Carlo N-Particle eXtended (MCNPX) general-purpose simulation techniques. Accordingly, was designed along ...

UNLABELLED A whole-body PET scanner, without interplane septa, has been designed to achieve high performance in clinical applications. The C-PET scanner, an advancement of the PENN PET scanners, is unique in the use of 6 curved NaI(Tl) detectors (2.54 cm thick). The scanner has a ring diameter of 90 cm, a patient port diameter of 56 cm, and an axial field of view of 25.6 cm. A (137)Cs point sou...

The high efficiency of the BGO detectors makes them very attractive candidates to replace NaI(T1) detectors, which are widely used in studies of body composition. In this work, the response functions of the BGO and NaI(T1) detectors were determined at 0.662,4.4, and 10.0 MeV using three different Monte Carlo codes: EGS4,l MCNP,2 and PHOTON.3 These codes differ in their input files and transport...

For nearly two decades the DAMA Collaboration has been observing a modulating signal compatible with that expected from dark matter presence in our galaxy. However, interpretations of this standard assumptions for particles are strongly ruled out by large number other experiments. This tension can be relaxed somewhat making more tailored choices model and properties interest, but expanding mode...

Crystal scintillators and in particular inorganic play an important role the investigation of Dark Matter (DM) other rare processes. The a DM signature, as annual modulation, or directionality technique requires use highly radiopure detectors able to explore very low energy region maintaining high stability running conditions. In this paper, cases NaI(Tl), ZnWO4 SrI2(Eu) crystal are described f...
