N2  - Chitosan films were prepared by casting technique and irradiated by (60Co) source  of Þ-rays with different doses 5,10,15, 20 and 25 kGy to improve their properties  to be used as a wound healing material. Characterization of the chemical structure  of the irradiated Cs films was by Fourier Transformer Infrared (FTIR) indicating  that Þ-irradiation caused depolymerization of the chitosan without changing its  chemical structure and without affecting the degree of deacetylation. Different  physical properties (mechanical, dielectric and degradation) of the irradiated  films were examined. It was concluded that irradiating chitosan films at dose of  5 kGy had the optimum for the properties of chitosan films and promising to be  used in the application of wound healing
