A state-of-the-art review of the effects of nuclear radiation on magnetic materials through 1959 was published by Gordon in 1960. The current paper supplements that review by summarizing the significant data obtained since that date at the Naval Ordnance Laboratory and elsewhere on reactor and charged particle irradiation effects on both soft magnetic materials and permanent magnets. New results obtained by the authors on the recovery of magnetic properties of proton irradiated iron and 5-79 Mo Permalloy are also presented.
