In spite of having higher carrier mobilities and absorption coefficients germanium (Ge) than those silicon (Si), there has been less focus on Ge-based solar cells due to the low bandgap high-cost Ge wafer as well requirement its high-purity level. Currently, availability (HPGe), low-cost slicing method proper design guidelines make it possible HPGe-based cells. Accordingly, in this article, we ...

Determinations of specific activity concentrations for Uranium-238, Thorium-232 and Potassium-40 in 10 commercial phosphate fertilizers samples from various countries (Iraq, Iran, Jordan, Kingdom Saudi Arabia, Italy Turkey) were accomplished by the use high purity germanium detector device. Radiation hazard indices [(Annual Effective Dose Equivalent) in, (Annual out, Equivalent Activity Radium,...

The gamma and X-ray emission intensities of 169Er were determined using radionuclidically pure 169Er. activity the source was standardized by triple-to-double-coincidence ratio technique. Three independent measurements performed to measure calibrated high-purity germanium spectrometers. efficiencies computed with Monte Carlo method validated several experimental measurements. Final results pres...

The measurement of β -decay rates in plasma, simulating stellar-like conditions, is high interest for the investigation radionuclides involved nuclear astrophysics processes. In new PANDORA plasma trap, to be built at INFN—Laboratori Nazionali del Sud Catania (Italy), will estimated by detecting γ -rays emitted daughter nuclei trapped confined plasma. present work describes efficiency High Puri...

The difficulty of locating and identifying radiological sources over large areas is well known. The signal strength of a small-volume source diminishes according to the familiar “inverse square law” as the detector is moved away from the source. Ever-present fluctuating background levels exacerbate the problem when the source strength is weak compared to the background count rates from other so...

Low background HPGe detectors have been used for many years in the measurement of low activities of radionuclides in various materials. With the increased importance of nuclear forensics, low background detectors are in increasing demand. The endcap and other materials used in low background detector construction must be selected to have the lowest activity possible. In some cases, the material...

High purity germanium (HPGe) detectors are ubiquitous in nuclear physics experiments and are also used in numerous low radioactive background detectors, including the proposed Majorana experiment. Spatial reconstruction of the location of radiation sources from spectral distortions could be used to locate unwanted backgrounds or “hot-spots” inside the detector shield. The effect of the position...

High purity germanium (HPGe) detectors are ubiquitous in nuclear physics experiments and are also used in numerous low radioactive background detectors. The effect of the position of Co and Cs point sources on the shape of spectra were studied with Monte Carlo and HPGe detector measurements. We briefly confirm previous work on the position dependence of relative heights of peaks. Spectra taken ...
