In this study, degradation and decoloration of aqueous solutions of reactive and acid commercial dyes and textile wastewater under electron beam irradiation were investigated. All samples were irradiated at different doses of 1, 3, 6 and 9 kGy. The changes of absorption spectra, degree of decoloration, pH, and chemical oxygen demand were analyzed. In addition to the influence of absorbed dose and hydrogen peroxide additions upon reactive black dye are discussed. Also microbial contamination of textile wastewater was measured before and after irradiation. The experimental results showed that reactive and acid dyes in aqueous solutions can be effectively degradiated by electron beam irradiation. The absorption bands for RB5 and AR151 decreased rapidly at 1 kGy irradiation dose and disappeared almost completely at 9 kGy. Also the degree of decoloration RB5 solution at 1 kGy dose and with increasing H2O2 concentrations up to 5 mmol\L was higer than 99\78%. Due to production of organic and inorganic acid anions the pH decreased during irradiation.<\div>
