Abstract

 AQUEOUS SOLUTIONS of pH indicators congo red (CR) and quinaldine red (QR) dyes were titrated by different concentrations of (H+) resulting from irradiation decomposition of chloral hydrate (CH) solution for possible use as an monitoring device (label) for gamma radiation. The titrated solutions were readout spectrophotometrically. The useful measuring range was found to be of 20 -100 kGy. Further calculation such as rate of reaction (r) and have been assigned. kinetic constant (k)
