Abstract
Measurements of the EPR signal amplitude of gamma-irradiated L-alpha-a lanine with use of an adjacent reference sample have revealed variatio ns in the signal intensity within hours and days after irradiation. Th e character of the time dependence of the amplitude varies with dose a nd the amplitude changes reach 1-1.5%. This observation favors the hyp othesis that irradiated alanine contains several paramagnetic centers. Usefulness of adjacent reference samples in alanine dosimetry is also demonstrated.
