Abstract

In studying the Ultraviolet (UV) radiation, one of the important factors is the possibility of generating a variety of free radicals inside the body by these radiations. In this paper, a method of estimating the amount of hydroxyl radicals produced by Ultraviolet rays was investigated using Nanoparticles of tin oxide doped with uropium. In this method, the change in absorption intensity of Methylene blue was used as a free radical Detector. SnO2: Eu Nanoparticles were synthesized using co-precipitation method and characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) analysis. The changes in the intensity of the Methylene blue absorption curve were investigated and it was found that this intensity decreases in the presence of Nanoparticles, which indicates the formation of free radicals in Ultraviolet radiation. Using the results of this method, it is possible to measure the amount of received Ultraviolet radiation dose.
