THE ACTION OF IONIZING RADIATION ON CABLE RUBBERS
The effect of direct ionizing radiation on different cable structures was studied as well as on insulation and rubber hoses subjected to irradiation in air, in vacuum, in water and at high temperatures. The insulation and hose were irradiated separately and in replicate with Co/sup 60/ over a wide range of doses up to 500 Mrad, intensity 0.3 Mrad/hr. Ionizing radiation caused deterioration in the physicomechanical and dielectric properties of the cable rubbers. With increase in the radiation dose>50 Mrad, an abrupt fall in the specific elongation and an increase in hardness were observed. The rubbers maintained satisfactory durability and did not possess elasticity. Up to 50 to 100 Mrad irradiation in water or in vacuum, changes in the properties of the rubbers are considerably smaller. Rubbers from natural sources are more stable to the simultaneous action of heating and irradiation than those from nairit. (Referativnyy zhurnal, Khimiya No. 8, 1962)
