Linnenbom, V J

Behavior of electrical insulation in a radiation field was considered from two viewpointsi temporary phenomena observed during irradiation, which depend largely on dose rate, and permanent effects that persist after removal from the field, which usually depend on total dose. Both organic and ceramic type materials showed increased conductivity and current leakage when exposed to radiation. Most of the induced conductivity disappeared within a short time after the irradiation ceased. With organic insulators, the permanent radiation damage was usually more of a problem than the transient effects. Inorganic insulation materials suffered far less permanent damage than the organic. The following materials are listed in order of decreasing radiation stability: ceramics, mica, glass, polystyrene, "Mylar," polyethylene, " Lucite," silicone rubber, nylon, and "Teflon." The effects of temperature, humidity, and the presence of surrounding gases during irradiation are discussed. (M.C.G.)
