A new compound was developed to obtain a radiation proof crosslinked rubber which shows the excellent performance than the usual elastomer i.e. ordinary EPDM(Ethylene-propylene-diene terpolymer) based one. As the first study,examinations were carried out with Co-60 -ray exposure tests at the room temperature for various candidate rubbers. Based on the exposure test of various rubbers, EPDM compounds were investigated in order to improve the resistance to deterioration under high radiation field. The high performance rubber was achieved by a blend of EPDM and IIR(Butyl rubber). In addition to the polymer system, antioxidant and aromatic oil were used as admixture. The most excellent new crosslinked rubber showed no bleeding, no brooming, less change of hardness and keep 150% elongation after the -ray irradiation over 7 MGy.
