Using the gamma spectroscopy system, it can be determined whether environmental samples or standard radioactive sources are radioactive, and from which elements their radioactivity originates. The purpose of Monte Carlo (MC) simulation is to model a real-life system with its inputs evaluate outputs real results. This study calculates experimental efficiency p-type HPGe detector using 0.5 g/cc E...

 ABSTRACTBackground: 226 Ra and 228 Ra contents in foodstuffs of Ramsar which is a coastal city in the northern part of Iran were determined by gamma spectrometry. Measurement results together with food consumption rates were used to estimate annual effective dose from  226 Ra and 228 Ra, due to consumption of food stuffs by inhabitants of Ramsar city.Materials and Methods: A total of 33 sample...

Nuclear reactions involving alpha particles play an important role in various astrophysical processes such as the gamma-process of heavy element nucleosynthesis. The poorly known low-energy alpha-nucleus optical (AOMP) potential is a key parameter to estimate rates these reactions. AOMP can be tested by measuring cross section alpha-scattering well alpha-induced Low energy elastic on 144Sm has ...

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 ...

This work aims to determine natural radionuclides (210Pb, 228,226Ra, 234,228Th and 40K) in NORM samples by well-type HPGe detectors because they are of vital importance studies on environmental samples. For this, a novel methodology has been developed, based obtaining general function for the full-energy peak efficiency (FEPE) versus sample apparent density composition, keeping height constant....

Proper characterization of waste is important to reduce the costs of disposal. The requirement for short data collection time often means putting the detector as close to the waste container as possible. Nondestructive assay of gamma ray emitting nuclear waste requires modeling because preparing a standard to match the physical and radiological properties of any waste item is not possible. Seve...

The concentrations of primordial radionuclides (226Ra, 232Th and 40K) in commonly used building materials (brick, cement and sand), the raw materials of cement and the by-products of coal-fired power plants (fly ash) collected from various manufacturers and suppliers in Bangladesh were determined via gamma-ray spectrometry using an HPGe detector. The results showed that the mean concentrations ...
