The conventional approach to the processing of airborne gamma-ray spectrometric data is to first sum the observed spectra over three relatively broad energy windows. These three window count rates are then processed to obtain estimates of the potassium (K), uranium (U), and thorium (Th) elemental abundances. However, multichannel spectra contain additional information on the concentrations of K...

Fast neutron activation analysis has been applied to bulk carbon detection. DT-neutron generator emitting 14.1 MeV neutrons was used as a source. Prompt 4.44 gammas from the inelastic scattering on were detected using 30% HPGe semiconductor gamma spectrometer shielded primary beam. The sensitivity of experimental setup is discussed. Keywords: Activation analysis; neutrons; Gamma spectrometry.

Introduction: Considering the risk of radiation, the measurement of the natural radiation sources seems to be necessary. In this study, the concentrations of the natural radionuclides, namely 226Ra, 232Th, and 40K, were measured in the soil samples taken from different locations of Golestan, Iran. The measurement results can also be used as a baseline to evaluate the impact of non-nuclear activ...

The linear attenuation coefficient (LAC) and mass (MAC) are most important while studying of radiation, radio-isotopes in dosimentry irradiation materials. In the present work to calculate values different salts samples by using Gamma-ray spectrometry with Photo-Multiplier Tube (PMT) Multi-Channel Analyzer (MCA). 0.123, 0.511, 0.662, 1.17, 1.28 1.33MeV gamma energy rays used for experiment inte...

The activity concentrations of naturally occurring radionuclides Ra-226, Th-232 and K-40, were measured by using a gamma ray spectrometry for coal, soil and water samples collected from the Barapukuria coal mine in Dinajpur district of Bangladesh. The average activity concentrations of Ra-226, Th-232 and K-40 in coal samples were found to be 6.21±3.68, 10.69±7.5 and 185.76±138.86 Bqkg, respecti...

In the frame of maintenance, upgrade and dismantling activities, activated equipment are removed from accelerator complex require characterization in view their disposal as radioactive waste. The process consists a series radiation measurements, complemented by analytical studies, which quantify activity radionuclides inside an object. A fraction waste produced at CERN presents contact dose-rat...

 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...
