Response of three types of aqueous chemical dosimeters to gamma and electron radiations in the dose range 0.1–10 kGy

Abstract

Three aqueous chemical dosimeters for the absorbed dose region 0.1–10 kGy—perchloric acid solution of silver dichromate, deaerated neutral solution of methanol, and buffered (pH ∼ 9.2) solution of bromophenol blue—were tested under both γ-ray and electron irradiation, at dose rates of ∼ 1 Gy s −1 and ∼ 10 5−10 6 Gy s −1, respectively. For many applications of high-dose measurement in radiation technology, variation of response with dose rate over this range may be considered negligible for all three systems.
