Statistical scission of cellulose macromolecules leading to the negative changes in mechanical properties of the paper has been quantified on irradiated stacks of newsprint papers. Attention has been paid to comparison of changes occurring in respective sheets of the stack. The correlation of the results of non‐isothermal chemiluminescence method from which the rate constant of paper oxidation has been determined for 105 °C with the changes of carbonyl groups concentration, pH and double folds has been outlined.
