An aqueous solution of pH indicator Resazurin dye (RZ) with and without containing chloral hydrate as an additive substance was studied for use as a liquid dosimeter. The dosimeter covers a range extended from 50 to 650 Gy depending on the concentration of both dye and chloral hydrate. Some of the properties about the dosimetry behavior were studied: its response to irradiation, the stability of dosimeter before and after irradiation, and an effect of different acidity on the response curve, G-value, the uncertainty of the measurement. All the recorded values encourage using this dosimeter in many sensitive dose applications.
