Exposure of vegetable-tammed, chrome-tanned and retanned leathers, and pickled calfskin to gamma radiation has been demonstrated to have a detrimental effect on the materials as shown by lowering of the shrinkage temperature, breaking strength, and elongation properties. The greatest damage occurred at the highest level of irradiation. Statistical analysis by matched-pair variance analysis of the data showed that very high significance could be attached to the decreases in physical properties obtained on all leathers irradiated to 10/sup 8/ and 10/sup 7/ reps. Irradiation at 10/sup 6/ reps caused significant decreases in shrinkage temperature of all the leathers: weak or no significance could be attached to the decreases in breaking strength and elongation propenties. No significance could be attached to differences between pickled calfskin control samples and specimens irradiated to 10/sup 6/ reps. Irradiation at 10/sup 7/ reps produced highly sigrificant decreases in shrink temperature and breaking strength properties. Irradiation of pickled calfskin in the presence of certain onganic compounds normally considered to be innocuous as tanning agents failed to induce tanning effects. Gluteraldehyde, probably because of its tamming ability, moderated the detrimental effects of irradiation. (auth)
