A set of chitosan samples irradiated by electrons with various doses was studied using the EPR method. Two kinds of paramagnetic defects, PC1 and PC2, initiated by this irradiation due to the breakage of bonds in positions C5 and C1 of the chitosan structure, are revealed in the “amorphous” and “cry...
