US/French joint research program regarding the behavior of polymer base materials subjected to beta radiation: Volume 3, Phase-2b expanded test results

This document is the final account of a multiyear joint NRC/CEA cooperative research program to investigate the relative effectiveness of beta and gamma irradiations to produce in polymer base electrical insulation and jacket materials. During the program jointly executed by research laboratories in the US (Sandia National Laboratories) and France (Compagnie ORIS Industrie), a number of material and radiation parameters were investigated. Results obtained were reasonably independent of the radiation parameters and most material parameters investigated and would suggest that material damage resulting from electron beam and gamma ray irradiations can be correlated, within limits, on the basis of absorbed radiation dose. 7 refs., 26 figs., 13 tabs.
