Comparative Study between Fabricated Plastic Scintillator and Existing Product for Gamma Detection

A plastic scintillator with an injection method has been developed for a gamma radiation detector. The was made from the main matrix of polystyrene (PS) pellets addition primary dopant PTP (para-terphenyl) 1.5% wt and secondary as wavelength shifter (WLS) POPOP (1,4-bis [2- (phenyloxazolyl) )] - benzene) 0.01 0.05% wt. mixture dopants fed to extruder machine obtain scintillating then referred 3 mm thin plate scintillator. evaluation absorption using spectrophotometer UV-Vis showed that PS absorbs photons at 310 – 340 nm containing produces maximum emission 421 nm. cesium 137 ( Cs) cobalt 60 Co) spectrum photomultiplier tube (PMT) Hamamatsu R878 results Compton characters gross counting 0.78 0.89, respectively, compared commercial this study are expected be usefully utilized in development large-volume portal monitor (RPM).
