FIELD: physics.
SUBSTANCE: based on measurement results of the nuclear magnetic resonance relaxation component, signal parameters of free induction and density of protons in cellulose samples from the surface layer of the cellulose-containing material on a coated section and on an uncoated section, the value G of relative changes of parameters of cellulose is determined and antiquity D of the event of creation of the object is determined by calculation based on the linear relationship between the values G and D.
EFFECT: simple procedure of determining antiquity of an event of creation of different types of objects from cellulose-containing material or objects having on their surface fragments made from cellulose-containing material without violating integrity of the article.
