Investigation of Incoherent Gamma-Ray Scattering Potential for the Fluid Density Measurement

Abstract

Incoherent gamma ray scattering is a method that can be applied for the fluid parameter characterization. The aim of the present work is to study the potential usage of the incoherent gamma ray scattering measurements to evaluate the fluid density based on the Monte Carlo approach. Enlarging the density of a fluid results in a significant reduction in the intensity of the detected gamma scattering. The difference of the simulation curve slope results in the gamma transmission mode its about 0.02 compared to the experimental result.

Determination of void fraction in two phase liquid-gas flow using gamma absorption

“…Although the measurement principle is not compound, but proper determination of the calibration curve requires high precision, appropriate methodology of research and carefully selected geometry of measurement. The sensitivity of this method depends on the energy of radioactive source or even their scattered radiation selection [6,7,13]. However, that selection is often restricted by the environment, pipeline material and components of the flowing mixture.…”

“…The authors experienced that the compound experiments design may be facilitated by simulations based on the program code MCNP (Monte Carlo N-Particle) [6].…”

“…The instantaneous or average value of a void fraction  can be designated at a fixed measurement. In that method the void fraction determination is based on the proper calibration of the measuring system [5][6][7][8]10]. This paper presents the calibration methodology of a radiometric set, which consists of gamma radiation source Am-241 and scintillation probe NaI(Tl).…”

Simulation of Void Detection System using Gamma-Ray Compton Scattering Technique

“…Several researches on NDT applications using gamma radiation have been conducted, such as observation of the differences in energy distribution and backscattering intensity of 1.12 MeV gamma photons emerging from Zn, Al, Sn, Fe, C as element targets and the compounds as a function of thickness and the atomic number (Z) target by Sabharwal, et al [15]; liquid density identification in polyethylene pipe using a 137 Cs gamma ray source by Wirawan, et al [16]; inspection of steel wire ropes on a suspension bridge using a 192 Ir gamma-ray source to determine and predict the resistance of steel wire ropes on a suspension bridge caused by corrosion and deformation, as presented by Peng and Wang [17]; and material inspection using gamma scattering techniques with 5 mCi (185 MBq) 137 Cs gamma sources and BGO detectors by Chankow, et al [18]. Void inspection in concrete has been performed with various gamma sources, detector types, and simulation methods.…”

Preliminary Study of Double Beta Decay: Simulation of CaMoO4 Scintillation Detector Response Function to the Gamma Ray Radiation

“…Monte Carlo simulation has been established as an appropriate method for modeling and useful for predicting the experiment results, especially for validation of the detector model [3]. In the previous study, we have successfully simulated the DRF of NaI(Tl) scintillation crystal using Penelope Monte Carlo GEANT4 [4]. Furthermore, in this work we focus to study the response function characteristic of CaMoO 4 crystal detector to the gamma ray radiation.…”
