Thus , the primary photodegradation of cellulose acetate is considered insignificant to the total degradation process , since cellulose acetate and its impurities absorb light at shorter wavelengths .
The atmosphere filters radiation from the sun and allows radiation of > 300 nm only to reach the surface .
