Characterization of dosimeters used in radiation processing

Abstract

Aérial L-alanine pellet dosimeter is characterized as the dispersion of dose measurement values in order to determine the level of uncertainty caused by dosimeter itself. The results of repeated measurements indicate that the uncertainty of 1.2% could be attributed to the homogeneity of alanine in dosimeter pellets. It was obtained by analyzing the results of measurements of the different dosimeters from the same batch that the uncertainty due to difference in dosimeter mass is 1%. The total uncertainty due to dosimeter itself is 1.5%.
