title: [Packaging in the process of radiation sterilization. II. Physicochemical studies].
abstract: The penetrability of the ionizing radiation through the matter makes possible the sterilization of the medical devices in the packed form by radiation method. The effect of the radiation should not bring any destructive changes in the material used for the package. In this paper have been discussed the results of the investigations of the one--and multilayer packaging materials from the point of view their utility for the radiation sterilization purposes. The changes of the useful parameters of the investigated materials have been determined in the dependence on the absorbed dose immediately after irradiation and the period of the durable keeping after the sterilization. The results of the mechanical investigations in the correlation to the results of the microbiological effects of the sterilized materials enabled to draw practical conclusions concerned the usability of the particular packages.
