Solid dicarboxylic acids as in-pile chemical dosimeters

Abstract

Radiolytic decomposition of succinic acid induced by mixed pile radiation was studied with respect to dosimetric use at high reactor power levels, from 2 to 10 MW, and dose rates from 20 to 120 Mrad hr -1-1. The linear relationship between the absorbed dose and the logarithm of weight losses caused by radiation, like in the case of solid oxalic acid, was found. The radiolytic behaviour of succinic acid and oxalic acid dihydrate is compared, especially the effect of temperature on the radiolysis.
