The present invention provides a radiation-resistant sheath material and a radiation-resistant cable that can be used as a sheath material for BWR and a sheath material for PWR and that can be used for a test by an inverse sequential method. A polymer material containing an ethylene unit as a main component in a molecular chain, in which side chain groups are randomly distributed and cross-linked, preferably a chlorinated polyethylene containing a chloro group in the side chain group, and a polymer material A radiation-resistant sheath 20 material having an anti-aging agent, a processing aid, and a flame retardant added therein, and a radiation-resistant cable 1 including the sheath material.
