Applied Radiation and Isotopes, 2021
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 ...

Density measurement of multi-layered material using gamma-ray transmission technique
Radiation Physics and Chemistry, 2021Abstract The densitometry measurement based on the gamma-ray transmission technique of 3-layers material (tin, aluminum, and lead) has been newly developed and studied in this work. The concept and the calculation method were briefly described and the results of each material were compared with Archimedes's technique.

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.

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

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.

On-line nuclear ash gauge for coal based on gamma-ray transmission techniques
Journal of Radioanalytical and Nuclear Chemistry, 1999Developments and applications of on-line nuclear gauges in the coal industry are highly requested. In this work, a nuclear ash gauge for coal, based on γ-ray transmission techniques is developed. Single and dual energy γ-ray beams are used to determine the ash content of coal.

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
