Background: This study aimed to investigate the radiation hazard indices from sand samples of Ma’rib Governorate in Yemen, where majority oil and gas facilities are installed. Methods Materials: Thirty five desert Yemen were collected tested their by using High Purity Germanium (HPGe) detector. Results: Based on measurement concentrations 226Ra, 232Th, 40K, radium equivalent activity (Raeq), co...

Measurement of natural radionuclides concentration in Samosir area of Sumatera island of Indonesia aims to obtain basis data of the content of radionuclides that could be tended in the development of the area. This research was conducted using Neutron Activation Analysis (NAA), which consists of a sampling of soil of Samosir Island as the residential area and the soil surrounding of Pangururan ...

Exposure to radioactive elements or having them through drinking water causes many biological risks. Therefore, it is important to investigate the drinking water especially in regions where people depend on well water for drinking. Concentrations of some radionuclides in some water wells, in Arar city of Saudi Arabia, were measured by using Hyper Pure Germanium (HPGe) Detector. Concentrations o...

Diatomite (diatomaceous earth) and clay minerals deposits from the mining basin Kolubara, Serbia, are natural materials with high economic potential in many fields. As received treated materials, diatomite were characterized using X-ray diffraction, mercury intrusion porosimetry, particle size distribution, scanning electron microscopy, Fourier-transform infrared spectroscopy. Activity concentr...

Gamma-ray spectrometry measurements performed on site, or “in situ”, is a widely used and powerful method that can be employed both to identify and quantify ground deposited radionuclides. The purpose of this thesis is to improve the calibration of high purity germanium (HPGe) detectors for in situ measurements, and calculate the combined uncertainty and potential systematic effects. An improve...

A new generation of high-resolution hypernuclear γ-spectroscopy experiments with high-purity germanium detectors (HPGe) are presently designed at the FINUDA spectrometer at DAΦNE, the Frascati φ-factory, and at PANDA , the pp hadron spectrometer at the future FAIR facility. Both, the FINUDA and PANDA spectrometers are built around the target region covering a large solid angle. To maximise the ...
