Gamma Sterilization of Health Care Products and Its Efficacy

Marsida Klemo, Andon Dodbiba

Abstract: Different single-use health care products were irradiated with different doses. For irradiation of the products was used the GU-3 gamma irradiator (with Cs-137) installed in the Institute of Applied Nuclear Physics in Tirana, Albania. The applied rotation technique provided an absorbed dose uniformity 106 % and average dose rate 4.68 Gy/min. Determination of health care products sterility was carried out in the Institute of Public Health according to a specific method. Sterility examination was performed almost one year after irradiation. From the study of results was confirmed that the use of gamma irradiation, to ensure the sterility of the products, is an effective method.
