| Abstract: | Aim To determine the aftereffect in the degradation of cotton cellulose. Methods After being radiated by 60Co ray and high energy electron, the viscosity of cotton cellulose were determined at different times by capilary viscometry . Results The viscosity of cotton cellulose decreased continuously at first , and kept constant after 1 5 days. Conclusion Cotton cellulose has radiation aftereffect, and there is a linear relationship between the logarithm of absorption doses and the total effect . |
