Radioactivity quantification of gamma-ray emitter radionuclides in samples measured by HPGe gamma spectrometers relies on the analysis of the photopeaks present in the spectra, especially on the accurate determination of their net areas. This paper presents a methodology and an algorithm description for the peak search and analysis in order to obtain the relevant peaks parameters and their unce...

The Nubian sandstone aquifer's hydrogeophysical and natural radioactivity parameters at the Northwestern part of El Ain village, Sharq Oweinat, Southwestern desert, Egypt are resolved using geophysical well logging techniques. study aims to monitor phenomenon appearing an unusual high gamma-ray a zone resistivity record. A nest logs is collected assess how widespread. Results correlated clarifi...

Neutron Activation Analysis (NAA) is an established nuclear analytical technique with applications in a broad range of scientific and technological fields. Typically, conventional NAA involves analysis of small material portions of 10 to 100 g in mass. However, analysis of samples of a larger mass implies a number of additional advantages such as (a) analysis of objects too precious to remove ...

Abstract Coral reef samples collected from the Egyptian Red Sea coast’s Quseir harbour were analysed using INAA technique for qualitative and quantitative analysis. The concentration of heavy metals, rare earth elements, elemental contents measured in coral reefs. assembled with their standards irradiated Egypt’s Second Research Reactor at same time (ETRR-2). gamma-ray spectra an HPGe detector ...

236 Performance Characteristics of a Third Generation Portable Radionuclide Identifier Ronald M. Keyser and Timothy R. Twomey ORTEC, 801 South Illinois Avenue, Oak Ridge, TN 37830 ABSTRACT The continuing need for a hand-held, portable radionuclide identifier for use in countering illicit nuclear trafficking and in positive identification of radioactive materials, benign or threat, has fostered ...

Precise β-branching-ratio measurements are required in order to determine ft-values as part of our program to test the Electroweak Standard Model via unitarity of the Cabibbo-Kobayashi-Moskawa matrix. For the measurements to be useful in this test, their precision must be close to 0.1%. In a branching-ratio measurement, we position the radioactive sample between a thin plastic scintillator used...

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...
