    Bojarski, J; Zimek, Z [Institute of Nuclear Chemistry and Technology, Warsaw (Poland)


    Radiation technology for production of radiation resistant polypropylene for medical use has been presented. The method consists in radiation induced copolymerization of polypropylene with ethylene and addition of small amount of copolymer of polyethylene and vinyl acetate. The material of proposed composition has a very good mechanical properties and elevated radiation resistivity decided on possibility of radiosterilization of products made of this material and designed for medical use. 3 figs, 3 tabs.

  2. Present studies on the radio-sterilized drugs; Aktualny stan badan nad lekami sterylizowanymi radiacyjnie

    Marciniec, B; Dettlaff, K [Department of Pharmaceutical Chemistry, Poznan University of Medical Sciences, Poznan (Poland)


    Lecture presents present status of radiosterilization of drugs and medical materials as compared to other sterilization methods. Literature review is shown on degradation of different kinds of drugs sterilized upon action of the sterilising doses of radiation.

  3. Criteria for permission of radiosterilized products to application in medicine; Zasady dopuszczania wyrobow sterylizowanych radiacyjnie do stosowania w medycynie

    Energy Technology Data Exchange (ETDEWEB)

    Achmatowicz, T [Instytut Lekow, Warsaw (Poland)


    The criteria being used in Poland for permission of radiosterilized medical materials to commercial application result from regulations being in force. The international regulations are also taken into account. The all criteria and procedure needed for any product become accepted for radiosterilization and commercial medical use have been presented and discussed. 1 tab.

  4. Prognosis of the application spices, nondecontamined and decontaminated by irradiation on the sanitary effect foodstuffs; Prognozowanie skutkow sanitarnych zastosowania przypraw niedekontaminowanych i dekontaminowanych radiacyjnie w artykulach spozywczych

    Using the elements of prognostic microbiology it has been shown that under conditions conductive to growth of microorganisms, the foodstuff which contains contaminated spices is characterized by lower quality. It may be the risk for human health. The prognosis has been shown, the microbiological decontamination of spices by irradiation may be one of the elements of new system - Hazard Analysis Critical Control Point (HACCP). (author)
