Fluorescence of aqueous sodium salicylate. Solutions under excitation by ionizing radiations

Abstract
The equations derived in the expanding sphere model1 are applied to the experimental results on the fluorescence from aqueous salicylate solutions under X-irradiation. The results fit the theory well over a wide concentration range and their deviation from the behaviour of the same system under u.-v. irradiation agrees quantitatively with a mechanism involving the non-homogeneous quenching by radiation-induced radicals of solute molecules excited by the same ionizing radiations.
