this study shows how collagen molecules are readily damaged by $gamma$ -radiation at dosages commonly used for sterilizing biomedical products. at 1 mrad, while the reported effectiveness of the radiation at such a low dosage to completely sterilize a material is questionable, less damage was caused to the collagen peptide backbone. it is shown that tissues exposed to high dosages of $gamma$ -radiation should be tested for long term functional changes. we want to caution against the usage of the enzyme degradation assay as a universal test for all bioprosthetic derived from biological tissues (edited author abstract) 10 refs
