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,

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 ...

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 ...
