Natural radioactivity assessment in soil samples from Kirkuk city of Iraq using HPGe detector
Background: Inspection of the level of radioactivity from radionuclides in soil is important for the assessment of the exposure to natural radiation. Materials and Methods: Ten samples from soil were collected from different sites of Kirkuk-IRAQ and the level of natural radioactivity was measured using gamma-ray spectrometry based on a high purity germanium (HPGe) detector. Results: It was foun...
متن کاملGamma-ray imaging with coaxial HPGe detector
We report on the first experimental demonstration of Compton imaging of gamma rays with a single coaxial high-purity germanium (HPGe) detector. This imaging capability is realized by two-dimensional segmentation of the outside contact in combination with digital pulse-shape analysis, which enables to image gamma rays in 4p without employing a collimator. We are able to demonstrate the ability t...
متن کاملMixed dark matter with low-mass bosons.
We calculate the linear power spectrum for a range of mixed dark matter (MDM) models assuming a massive (few eV) boson, φ, instead of a neutrino as the hot component. We consider both the case where the hot dark matter (HDM) particle is a boson and the cold component is some other unknown particle, and the case where there is only one dark matter particle, a boson, with the cold dark matter (CD...
متن کاملThe Best Choice of High Purity Germanium (HPGe) Detector
below and are based on some basic concepts about how the detection process works, how gamma rays penetrate materials, and the principles of gamma-ray spectroscopy. Unresolved choice issues can be reduced to a level where they have little or no impact on the resultant performance of the spectrometry system. This document explains how you can easily make a wise, well-informed choice. We assume yo...
متن کاملPosition sensitivity of the first SmartPET HPGe detector
In this paper we discuss the Smart Positron Emission Tomography (PET) imaging system being developed by the University of Liverpool in conjunction with CCLRC Daresbury Laboratory. We describe the motivation for the development of a semiconductorbased PET system and the advantages it will offer over current tomographs. Details of the detectors and associated electronics are discussed and results...
