Abstract : RG-58/u, RG-59 B/u, and RG-62/u coaxial cables were exposed to pulsed radiation in the Diamond Ordnance Radiation Facility (DORF) reactor. Conductance and replacement currents were measured with two different cable configurations--one with the irradiated portion looped into a hairpin shape, the other with the irradiated end of the cable fastened to a terminal board and the entire assembly exposed to the radiation. Data were obtained as a function of distance from the radiation source in the reactor and in a neutronfree Co60 gamma ray environment. The test results suggest that the polarity of the replacement current depends on the energy and type of incident radiation. It was determined that cables can be used to perform experiments in DORF without introducing more than 0.8 microamp replacement current at the peak of the reactor pulse. (Author)
