Abstract

In the present work, radiosensitivity and dosimetric potential of solid trisodium citrate dihydrate (SC) were explored through a detailed electron spin resonance (ESR) study performed at various temperatures. Irradiated SC was observed to exhibit an ESR spectrum consisting of many intense and weak resonance lines spread over a magnetic field range of 7 mT and centered at g = 2.0039. An evaluation technique based on the variations of the characteristic resonance line intensities and the spectrum area under different experimental conditions was adopted, to determine the spectroscopic, kinetic and dosimetric features of radical species responsible for the observed experimental ESR spectrum. Radicals exhibiting similar ESR characteristics to those reported in the literature for irradiated tricarboxilic acids and their organic compounds were shown to be also produced in gamma-irradiated SC.
