The results of the investigations of  radiation-chemical  influence on synthetic petroleum from bituminous rocks  of Balakhany’s deposits in Azerbaijan are offered. The investigations were carried out on gamma-source ⁶⁰Co at power of dose in P=0.5 Gy/s and absorbed dose D=43–216 kGy. The results of chromatographic and IR-spectroscopic investigations of synthetic petroleum samples from natural bituminous rocks are presented, and their radiation stability estimated. The results of  such studies permit to appraise the possibility of obtaining oil products for the various purposes by radiation-chemical way, as well using these materials for insulation of radioactive sources from the influence a the environment
