Abstract
A study was made of the formation of charge particles and free radicals in a number of polymers during photoradiation as a function of the intensity and integral dose of ionizing radiation, light intensity and frequency. A relation was established between the intensity of recombination luminescence and the dose of ionizing radiation and the formation of intermediate particles taking part in free radical formation during photoradiation. A correlation was derived between the frequency dependence of the photoradiation effect and optical absorption spectra of polymers subjected to γ-radiation at 77°K. It was shown that the formation of free radicals, in addition to those formed during radiolysis, by the action of photo-radiation is due to the use of the light energy absorbed by free radicals and stable products of the radiolysis of the polymer. The recombination mechanism of free radical formation and vibratory activation in charge recombination and deactivation of electron activated states of molecules was described.
