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. Published by Elsevier Science Ltd
