To investigate the possibility to characterize radioactive wastes using available information and measurements in a coherent frame, Bayesian formalism is built couple gamma-ray spectrometry tomographic scans. The gamma ray performed with four High Purity Germanium (HPGe) detectors placed around waste scanning 2 cm thick slices of drum Gamma Scanning mode. tomography provides density matrix iden...

In situ, high-resolution, gamma-ray spectrometry of a total number of 70 outdoor and 20 indoor representative measurements were performed in preselected, common locations of the main urban areas of Cyprus. Specific activities and gamma absorbed dose rates in air due to the naturally occurring radionuclides of (232)Th and (238)U series, and (40)K are determined and discussed. Effective dose rate...

this study was conducted to determine the radioactivity concentration in soil samples of anarak-khour district located at central iran. 48 soil samples from a depth of 10-15 cm were taken from seven different sites for monitoring. the radioactivity concentration of 238u, 232th, 137cs and 40k in soil samples was determined, using a high resolution (hpge detector, p-type) γ-spectrometry by detect...

Abstract. The objective of this work is to simulate the spectral gamma-ray response NaI(Tl) scintillation detectors for airborne spectrometry (AGRS) using state-of-the-art multi-purpose Monte Carlo code FLUKA. study based on a commercial detector system with four individual crystals and total volume 16.8 L. To validate developed model, radiation measurements were conducted 57Co, 60Co, 88Y, 109C...

Distributions of primordial radionuclides in soil and vegetables were investigated using high-purity germanium gamma-ray spectrometry. Gamma-ray spectrometry is one of the most accepted and widely used techniques for the detection and analysis of radioactive materials for a wide range of activity. Important properties of the employed gamma-ray detector were also determined to ensure the accurac...

Portable EDXRF (Energy Dispersive X-Ray Fluorescence) spectrometer with the ability to perform rock tests in a helium atmosphere was applied prepare unique calibration coefficients and mineralogical models. These data could be used for chemical profiling, chemostratigraphy, gamma-ray, TOC lithological interpretation of borehole geological profile. The measurements were conducted on 19 samples s...
