The mechanical properties of polymers during irradiation were studied with a powerful source from a nuclear reactor. The experiments were carried out in water-cooled ventical wells. The neutron flux, quanta, and the energy dose received by the specimens were measured. The latter was determined by the initial heating rate of dosimetric specimens prepared from identical materials. By varying the reactor power the dose was varied up to ~50,000 r/sec. The reversible radiation-mechanical effects observed in polymers during irradiation were not observed after irradiation was stopped. The observed effects were expressed by a lowered polymethyl methacrylate stability, lower limits of induced elasticity, and expansion of ruptures in polyvinyl chloride, increased relaxation rates, and increased creep in polyvinyl chloride, polystyrene, teflon, and rubber.
