title: [Resistance of polysterenes and styrene-acrylonitrile copolymer to sterilizing doses of accelerated electron radiation].
abstract: The results of the study on the resistance of certain home-made polystyrenes to sterilizing doses of accelerated electron radiation are shown. The properties of studied materials were found to undergo no changes after sterilization and one-year's storage which, in a majority of cases, qualifies them suitable for manufacture of medical and bacteriological equipment to be sterilized in electron accelerators. One of the materials under study - type KM polystyrene with increased impact resistance - was found to be relatively unstable in its commercial form before irradiation. The styrene-acrylonitrile copolymer, although completely radiation resistant within the examined dosage range, requires special caution because of free actylonitrile found in extracts.
