Humic substances (HS) of different origins have been labeled with tritium by the thermal activation method. Specific radioactivity HS ( 3H-HS) was sufficiently high and varied from 0.14 to 0.6 TBq/g. Parent 3H-HS were analyzed size exclusion chromatography UV detection. The results allowed concluding that (1) neither partial decomposition nor polymerization occurred during labeling (2) molecules a regular distribution among fractions molecular weights. performed correlation analysis revealed there no significant relationship between properties specific obtained 3H-HS. Thus universality developed technique for radioactive could be demonstrated.
