An approach based on gamma-ray transmission technique and artificial neural network for accurately measuring the thickness of various materials

open access: yesNuclear Technology and Radiation Protection
This paper presents an approach based on the gamma-ray transmission technique and artificial neural network for accurately measuring the thickness of various materials in flat sheet form. The gamma-ray transmission system comprises a NaI(Tl) scintillation detector coupled with a 137Cs radioactive source.
