Study on Gamma Irradiation on Sago Starch-Chitosan-PVA Blend Films

Blends from sago starch, chitosan, polyvinyl alcohol (PVA) and distilled water have been prepared and subjected to gamma irradiation with doses ranging from 10 to 30 kGy. In some circumstances silver nitrate solution was added to the blends. The blends were then dried in an oven to form films. Some characteristic of the films were then determined.
