The aim of this study is to investigate the structural changes of Al doped ZnO thin films with gamma transmission technique with Cs-137 gamma radioisotope source. Gamma transmittance and gamma absorption coefficient, (1/mm) were investigated with the increase Al (at.%) concentration. Hence it can be possible to assess the density for Al doped ZnO thin

Abstract This paper presents a new approach for determining the thickness of material plates by gamma-ray transmission technique using calibration curves obtained from simulated spectra through the Monte Carlo algorithm. The narrow transmitted gamma-ray beam from a collimated source of 137Cs (with the energy of 661.7 keV) for different thicknesses of

Abstract Quality of fluidization is an important criterion for efficient heat and mass transfer in gas–solid fluidized beds. Knowledge of voidage distribution in fluidized bed is essential when exothermic reactions are carried out in fluidized beds.

The study presents a new ANN-based approach to determine the density of a liquid applied in the gamma transmission and gamma scattering techniques. This approach used the Monte Carlo simulation combined with an artificial intelligence technique and experimental data to estimate the density of liquids.

Annulus flooding detection system in flexible pipes using gamma rays transmission technique
Applied Radiation and Isotopes, 2022Flexible pipes are modular constructions made up of several layers. They are broadly employed in oil & gas industry, playing an important role in the Brazilian Pre-Salt production. Under specific conditions, seawater can ingress and this contact with metallic middle layers can significantly lead to a service life reduction of these layers, especially ...

Gamma-ray transmission technique for quality control of coal seams
Canadian Journal of Physics, 2002The useful heat value (UHV) that is the figure of merit for coal depends on various parameters such as fixed carbon, volatiles, ash, and moisture. The percentage of these materials present in a given sample of coal can be estimated by gamma-ray transmission studies.

Rapid quality control for coal seams by gamma ray transmission technique
Applied Radiation and Isotopes, 1999Abstract The quality of coal expressed as useful heat value (UHV) depends on various parameters such as fixed carbon, volatiles, ash and moisture. These factors have been assessed and the detailed dependence of UHV on these parameters has been studied for samples of coal from a local mine.

This study proposes an approach based on the gamma-ray transmission technique to accurately determine the thickness of material plates using a low-activity source. For this purpose, we have set up an experimental configuration without collimators for both source and detector.

Abstract In this study, we propose a new approach for determining the density of liquid based on the gamma transmission technique in combination with Monte Carlo simulation. This approach involves analysing the sensitivity of the measurement whilst changing the diameter of a tube containing a liquid and then based on the simulated data to construct a
