THE RELATIVE RESPONSE OF FRICKE, DICHROMATE AND ALANINE DOSIMETERS TO ~(60)Co AND HIGH ENERGY ELECTRON BEAM RADIATION

摘要

The relative response of Fricke, dichromate and alanine dosimeters to ~(60)Co 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 ~(60)Co or high energy electron beams. The response of dichromate dosimeters is, however, approximately 3% lower in electron beams than in ~(60)Co. 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.
