Radiation-resistant plastic scintillator on a polystyrene-polyphenymetylsiloxane mixed base

In this work, plastic scintillators based on mixed polystyrene-polyphenylmethylsiloxane have been created, and their mechanical and scintillation characteristics have been studied. The created plastic scintillators based on polystyrene containing 30 wt. % polyphenylmethylsiloxane, demonstrated radiation resistance reaching 22 Mrad. The obtained PSs retain their physical and mechanical properties at a level that ensures ease of mechanical processing of the material and makes it possible to obtain samples in a wide range of shapes and sizes.
