The 8 MeV electron radiation-induced changes in physical and thermal properties in P31 (<i>Bombyx mori</i>) silk fibers were investigated and has been correlated with the applied radiation doses. Irradiation of fiber samples were carried out in dry air at room temperature using an electron beam accelerator for varied radiation doses in the range of 0-100 kGy. Physical properties of the irradiated silk fibers were studied using XRD, FT-IR and thermogravimetric analysis (TGA) and compared with unirradiated fiber sample. Interesting results are discussed in this report.
