Radiation sterilization of cellulose dressing materials

The results of investigations in the field of application of 60 Co gamma-irradiation for sterilization of cellulose dressing materials have been presented on the ground of our own experiments. The investigations were carried out for the model objects which are contents of all dressing materials, nowadays used in medical practice: cotton gauze, viscose-cotton gauze, cotton wool and cotton-viscose wool. In the present report there have been discussed the results of the test estimation of sterilized materials immediately after irradiation and during long storage as well (3-5 years after irradiation). The estimation was carried out according to the requirements of Pharmacopoeia. Moreover, the choice of parameters of sterilization process from the view-point of microbiological experiments and estimation of initial contamination degree of irradiated materials have been discussed.
