The relative response of fricke, dichromate and alanine dosimeters to 60Co and high energy electron beam radiation

Abstract

The relative response of Fricke, dichromate and alanine dosimeters to 60Co and high energy electron beam radiation has been determined directly using graphite calorimeters. The response of Fricke and alanine dosimeters is not significantly different in 60Co or high energy electron beams. The response of dichromate dosimeters is, however, approximately 3% lower in electron beams than in 60Co. Differences between the effective density of the dosimeter and the material surrounding it have been shown to be a significant source of error in electron beam dosimetry.
