“…Gamma-ray computed tomography is a type of industrial tomography methods which has its applications in a wide range of areas such as oil and gas, chemical, geological sciences, etc. [1][2][3][4][5][6]. In each application, different sources such as cobalt-60, cesium-137 or Amersium-147, as well as different detection systems such as arrays, flat panels, types of scintillation detectors, semiconductors, etc., can be used in different configurations depending on the dimensions of the objects under investigation.…”

In this work, an industrial gamma-ray-based computed tomography system is constructed using a 50 cm rod plastic scintillator coupled to PMTs at both ends. The ability of the system is evaluated using two phantoms: one for contrast and one for spatial resolution. Different cross-sectional images are reconstructed for the phantoms using MLEM algorithm to extract evaluation parameters. Such a system is suitable for scanning large objects due to its spatial resolution limitation, which is about 1 cm.

The development, preparation, and properties of new plastic scintillators, based on polyvinyl toluene matrix EJ-290 and only one luminophore with a large Stokes shift, are addressed. The primary luminophores tested were 2-(1-naphthyl)-5-phenyloxazole, 1-phenyl-3-mesityl-2-pyrazoline, and 2,5-bis(5-tert-butyl-benzoxazol-2-yl)thiophene. These were subsequently compared with the commercially used luminophores 2,5-diphenyloxazole and p-terphenyl in combination with wavelength shifters (secondary luminophores) 1,4-bis(2-methylstyryl) benzene and 1,4-bis(5-phenyl-2-oxazolyl)benzene made from the same polyvinyl toluene matrix in the same dimensions. For plastic scintillators produced in this way, their detection properties, such as Compton edge and detection efficiency, were characterized.
