Super highly radiation-resistant grease
 A radiation-resistant grease that is stable under elevated temperatures is disclosed. The grease is prepared by mixing a bentonite-based thickening agent with a base oil composed of m-(m-phenoxyphenoxy)diphenyl, pentaphenyl ether, a monoalkyltriphenyl ether or a monoalkyltetraphenyl ether (provided that the alkyl group contains 6-20 carbon atoms). To the mixture is added, if necessary, a gelling aid composed of an aliphatic alcohol, an aliphatic ketone and/or an aliphatic carbonate ester.
