%X this paper presents results of radiolytic degradation of 4-chlorophenol in the presence of tio2, al2o3, y sio2, using different radiation sources than 60co, which is so common in this type of experiment. the radiation sources used were x-rays with energy of 100 kev and radiation from 137cs (662 kev). after irradiation with a dose of 50 cgy x-ray and tio2 obtained a degradation of about 5%, no degradation was obtained with 137cs source and other oxides. this may be due to the fact that x-rays have a linear energy transfer (let) greater value, and in the case of tio2 present a crystalline structure, whereas the other two oxides are amorphous. both characteristics result in better formation of a reactive species that allows the degradation of the compound.
