ABSTRACT:
A radiation resistant composition includes 100 parts by weight of a polymer, 5 to 80 parts by weight of an aromatic series process oil that a polycyclic aromatic (PCA) extract by an IP 346 method (DMSO extraction) is not more than 3% and an aromatic compound content is not less than 20% by a Kurtz analysis, and a radiation resistance imparting agent. The polymer is cross-linked or vulcanized. A wire or a cable includes an insulation and/or a sheath material including the radiation resistant composition.
