NEUTRON AND GAMMA RADIATION EFFECTS ON DIELECTRICS

Abstract

Exposure of the following materials has no significant permanent aftereffects on dielectric constant and dissipation factor, measured at 60 cps, 1 mcs, and 30 mcs, nor on dc volume resistivity, nor on the dc and 60 cps surface resistivity of these dielectrics: asbestos fabric phenolic, asbestos- filled phenolic, asbestos-filled diallyl phthalate, mica-filled phenolic, alumina, forsterite, paper-phenolic laminate, polystyrene, polytetrafluoroethylene and polyethylene dielectrics to pulsed fast neutrons, ranging from 1.63 x 10 to the 12th to 2.0 x 10 to the 12th Nvt, and to gamma radiation at the rate of 2.8 x 10 to the 4th r/hr up to a total dose of 5.88 x 10 to the 5th r.
