Changes in the crystalline structure of silk sericin and silk fibroin induced by gamma-irradiation in the atmosphere described. The crystalline structure of silk sericin which had been subjected to gamma-irradiation remained unchanged. However the decomposition temperature of the specimen decreased to about 230°C, when the total dose of γ rays exceeded 4.6 Mrad. The structure of the silk I type crystal of silk fibroin in the solid state, with a low degree of molecular orientation, changed into the silk II type crystal, when the total dose of γ rays exceeded 4.6 Mrad. No changes in the crystalline structure were observed in the solid state of the silk II type crystal regardless of gamma-irradiation. The decrease in the decomposition temperature of the specimen was attributed to the decrease in the molecular orientation. However, the molecular conformation of silk fibroin with a randomly coiled structure remained unchanged even after gamma-irradiation.
