Abstract
Abstract Influence of irradiation dose, 0.1–1.0 MGY of 60Coγ-ray on the isothermal decomposition of doped (Ba2+) caesium bromate has been investigated. The α-t plots at 673.0 K explore that the process occurs through initial gas evolution, acceleratory and decay stages. Though irradiation reduces the value of “α”, the fraction decomposed in the initial period, it enhances the latter at higher time intervals. The data are well fitted to various kinetic equations like Prout-Tompkins, Avrami-Evofeev, and contracting square and indicate that the rate constant of the acceleratory stage is decreased by irradiation and is increased with increasing radiation dose, whereas that of the decay period is enhanced by irradiation.
