✦ Synopsis

Radiation-induced free radicals held in the matrix of organic solids are extremely stable, as evidenced by lyoluminescence studies of the solids, even a long time after irradiation. Stability contributed by their being held in the matrix has been studied by annealing with not much evidence Gf decay when annealed for a long time at temperatures approaching melting points. In the present experiment, time of decay of trapped radicals in high-temperature ice states of 1'-ray irradiated saccharides has been studied by lyoluminescence and ESR spectroscopy.

## Abstract The decay of free radicals in irradiated PMMA subjected to high pressures has been studied by the method of ESR. The rate constants and activation energies has been determined for the decay of free radicals at the pressures of 5000 and 10,000 atm over the temperature range of 100–170Β°C.
