Abstract : The effects of reactor radiation and LINAC irradiation on the dielectric properties of several common capacitors are compared. The dependence of the induced currents generated on applied voltage, geometry, dose, and dose-rate, is contrasted for mylar, polystyrene, mica, tantalum, glass, and ceramic capacitors. These effects are analyzed in terms of models appropriate for the various capacitors and their associated parameters are defined. Induced currents in irradiated thin-film resistors are principally due to secondary emission and air ionization. Static tests of ferrite core memory planes and magnetic tape were conducted at LINAC. The purpose was to determine whether these materials would retain stored information after radiation exposure. (Author)
