The encounter complexes, which are formed in polystyrene (PS) and PS-based scintillators, combine the excimers and luminescent dopants with benzyl macroradicals known as efficient paramagnetic traps of excitation. The quenching of electronically exci

The radiation-chemical yield of macroradicals was found to be many times higher under exposure of polymers (polystyrene, poly(methyl methacrylate), and polycarbonate) to ionizing radiation at extremely low dose rates (0.1–1 mGy/s) in a vacuum at ro

Radiation processes in plastic scintillators (PSs) are studied to establish that, first, macroradicals are the main quenchers of radiation-induced luminescence in the PSs, and, second, molecular oxygen initiates the decay of macroradicals. Based on t

The radiation-chemical processes investigated in polymers show that the macroradicals are responsible for the plastic scintillator radiation degradation. The reversible character of the radiation damage makes it evident that macroradicals are the exc

Increase in the intensity of the background line was found during measurement of the combination light scattering spectra with increase in the absorbed dose in PMMA. The “background” band is insensitive to change in temperature from 210 to 300 K
