THE EFFECT OF RADIATION ON THE ELECTRICAL RESISTIVITY AND BULK COMPRESSIBILITY OF POLYEPOXIDES.
Abstract
Three polyepoxides were exposed to varying doses of mixed neutron and gamma radiation in the University of Maryland nuclear reactor. Before irradiation, the electrical volume resistivity and the bulk compressibility of each of the polymers were determined as a function of temperature. The changes produced in these two parameters by radiation doses up to 25 Mrads were progressively followed by measurements after each radiation cycle. The results of this study indicate that radiation of this type and intensity will degrade crosslinked polyepoxides and that this can be shown by electrical resistivity measurements and by changes in the bulk compressibility.
