- Abstract
This research examines the effect of γ-ray irradiation at different temperatures (room temperature and 250°C) and atmospheric conditions (air and N2) on the electrical and mechanical characteristics of thermoplastic polyimide (TPI) insulated and sheathed coaxial cable, which is designed for high-temperature, radioactive use. It was found that the TPI insulated and sheathed coaxial cable had good radiation resistance at 250°C under N2, γ-ray irradiation of 75 MGy under air and electron beam irradiation of approximately 100 MGy under He. It was also found that both crosslinking and crystallization of TPI was accelerated by the synergistic effect of heat and γ-ray irradiation. © 1997 Scripta Technica, Inc.
