We are exploring the possibility of using PIN photodiodes to readout the scintillation crystals used in Positron Emission Tomography (PET) detector designs. Semiconductor photodetectors typically have a lower signal to noise ratio than photomultiplier tubes (PMTs). However, they have the advantage of compactness, and, thus, scintillation crystal readout schemes not available to PMTs because of ...

background: ct is a diagnostic imaging modality giving higher patient dose in comparison with other radiological procedures, so the calculation of organ dose in ct exams is very important. while methods to calculate the effective dose have been established (icrp 26 and icrp 60), they depend heavily on the ability to estimate the dose to radiosensitive organs from the ct procedure. however, dete...

Scintillation detector is widely used for the particle detection in field of physics. Particle detectors containing fluorine-19 ($^{19}\mathrm{F}$) are known to have advantages Weakly Interacting Massive Particles (WIMPs) dark matter search, especially spin-dependent interactions with WIMPs due its spin structure. In this study, scintillation properties carbontetrafluoride ($\mathrm{CF_{4}}$) g...

Department of Nuclear Engineering, Graduate School of Enginering, Nagoya University, Furo-cho, Chikusa-ku, Nagoya, Japan ABSTRACT Radon (Rn) diffusion coefficient as one of some important parameters of Rn transport in the soil has been measured using soil radon diffusion monitor (SRDM). The system of SRDM consists of two scintillation detectors, sample container located between these detectors,...

Scintillation single crystal fibers (SCFs) have great potential applications in the new generation of high-energy ray and particle detectors due to their morphological advantages. In this work; Ce:LuAG SCFs with a diameter 1 mm were grown along direction [111] by laser-heated pedestal growth (LHPG) method using transparent ceramic as source rod; doping concentration was 0.1 at%, 0.3 respectivel...
