In this work, A computer simulation was implemented to study ultraviolet radiation effect on charging process for a dust grain was immersed in to plasma (K^+and electron) with negative ion〖 (SF〗_6^-). The simulation based on discrete model and Orbital Motion Limited theory (OML). The numerical results were illustrated charge fluctuation of dust with time for different values of ultraviolet rays intensities and appeared increase of positive charge of dust when rays intensity increased.
