Abstract: The article considers the possibility of creating a radiation-resistant plastic scintillator based on polystyrene using a dialkyl derivative of biphenyl – 4,4′-di-tert-butylbiphenyl. Two types of scintillators were obtained: in the first, 4,4′-di-tert-butylbiphenyl was used as an activator, and in the second as a diffusion enhancer. The spectral-luminescent and scintillation properties of the obtained materials were studied, and their radiation resistance, as well as microhardness, were determined. A plastic scintillator containing 20 wt. % 4,4′-di-tert-butylbiphenyl was created, the light output half-attenuation dose of which is 163 kGy.

Keywords: 4,4′-di-tert-butylbiphenyl, plastic scintillator, radiation resistance, light output, microhardness.
