Comparative Evaluation of Polystyrene-based Plastic Scintillator for Gamma Detection | Chapter 2 | Fundamental Research and Application of Physical Science Vol. 5

 The objective concerning this study is to provide valuable information for the lie of large plastic scintillators that maybe utilized in radiation gate monitors (RPMs). A plastic scintillator was fabricated utilizing the injection system, with polystyrene (PS) as the matrix, and para-terphenyl (PTP) and 1,4-repeated [2- (phenyloxazolyl)] - benzene (POPOP) as primary and secondary dopants, individually. The scintillator was characterized based on allure absorption range, emission spectrum, and gamma fallout spectrum. The absorption range evaluation utilizing a spectrophotometer UV-Vis revealed that PS absorbs photons at a wavelength of 310 – 340 nm. The issuance spectrum evaluation displayed that PS containing POPOP exhibited a maximum diffusion at a wavelength of 421 nm. The judgment of cesium 137 (137Cs) and cobalt 60 (60Co) gamma spectrum utilizing the photomultiplier tube (PMT) Hamamatsu R878 showed that the scintillator shown Compton spectrum traits, with a gross counting maximum of 0.78 and 0.89, individually, compared to a commercial flexible scintillator.
