Monte Carlo approach to evaluate the small angle scattering effects in collimated beam by gamma transmission technique

Journal of Nuclear Science and Technology
This study introduces a Monte Carlo simulation method to remove small-angle scattering from gamma transmission spectra. Using MCNP-CP v3.2, it employs a collimated 137Cs source emitting a 662 keV gamma narrow beam, targets of varying thickness, and a NaI(Tl) detector.

Development of gamma rays transmission measurement technique for thickness determination of multi-layer materials [PDF]

AIP Conference Proceedings, 2018
The concrete, red brick and iron were used for thickness determination of multi-layer materials. The 133Ba, 137Cs and 60Co radioactive source were used energy at 356, 662 and 1173 keV for gamma rays transmission measurement technique. The dispersive X-ray fluorescence spectrometer (EDXRF) was used to confirmed the chemical composition with all sample ...

A Dual Energy Gamma-Ray Transmission Technique for Gold Alloy Identification.

RADIOISOTOPES, 1991
An application of the dual energy gamma-ray transmission techniques to gold alloy identification is presented. The measurement by dual energy gamma-ray transmission is independent of thickness and density of a sample. Due to this advantage, golden accessories such as necklaces, earrings and rings can be assayed inspite of their various thicknesses and ...

Shielding Effect of Aluminum Against Cs-137 Source, According to Gamma Ray Transmission Technique

Journal of Engineering Technology and Applied Sciences, 2022
In this study the shielding effect of the Aluminum element against radiation is referred to by using the gamma ray transmission technique. Selected gamma-ray source Cesium is monoenergytic and not necessary the activity correction due to its half-life. Absorption caused by aluminum leads to a reduction in the radiation dose exposed. In the literature,

Immunogenicity of two‐dose sinopharm BBIB‐CorV vaccine in Morocco: One‐year follow‐up and neutralizing activity against severe acute respiratory syndrome coronavirus 2 variants of concern

Immunity, Inflammation and Disease, Volume 12, Issue 11, November 2024.
This study assessed the immune response to the Sinopharm BBIB‐CorV vaccine against SARS‐CoV‐2 over a period of 1 year, using a two‐dose regimen. Conducted at the Military Hospital of Rabat, Morocco, the study found that additional booster vaccinations may be necessary based on the observed immunogenicity against various virus variants.
