Bioburdens on seven kinds of medical products were determined in accordance with ISO 11737. Different data were obtained for different products. The bioburden changed from 10 cfu/device to 97271 cfu/device the recovery ratio from 54.6% to 100%,and the correcting coefficiency from 1.0 to 1.8. Based on such bioburden and method 1 of ISO 11137,the verification dose was set up for each kind of products,from 5.1 kGy to 17. 6 kGy. 100 samples were taken respectively from each kind of products and exposed to the pre — defermined verificction dose. The sterility test showed the positive number was not more than 2. Thus the sterilication dose was determined according to Table B.1 of ISO11137.
