In the present investigation, Raman spectroscopy is used to study the modifications caused by Compton electrons, originated by gamma quanta of 
Co on the crystalline structure of graphite. The samples were irradiated in a dose range between 40 and 160 kGy. The analysis of the Raman spectra allowed to corroborate the electrons that occur at these radiation doses are able of causing appreciable modifications in the graphite structure. These modifications have a complex dependence of radiation dose due to the concurrence of the “radiational damage” and “radiational annealing” processes. The analysis of the fine structure of the Raman 2D band shows that the effect of the Compton electrons goes beyond the production of vacancy-interstitial pairs, since it leads to the modification of the disposition and stacking order of the plans in the structure of graphite.
