Abstract: As a research object it has been used the samples of petrol AI-92 from the oil of Azerbaijan. Laboratory studies have been conducted on gamma-source Co60 at dose rate P=0,18 Gy/s within the absorption dose range D=15-150 kGy. The results of chromatographic, IR-spectroscopic studies have been given. The viscosity and density of the samples have been determined. Concentration, radiation-chemical yields of the obtained gases at different absorption doses of the samples of petrol AI-92 have been determined and their radiation resistance has been evaluated. The methods applied to determination of radiation stability are based on radiation of a product and the subsequent determination of the changes which happened in it. Impact of radiation on operational characteristics of fuels in static conditions on a regular technique before radiation was researched. Radiation oxidations of processes considered in the field of low temperatures when chain processes don't happen. The purpose of this work is the research of radiation firmness of fuels from oils of Azerbaijan. Results of such researches allow to estimate radiation stability of fuels, to find out influence of irradiation on general composition of fuels and possible changes of qualities of fuels.Abstract: As a research object it has been used the samples of petrol AI-92 from the oil of Azerbaijan.

Abstract: The history of the formation and development of the theory of chain reactions is briefly presented. In specific examples the mechanisms of branched chain processes, conditions inhibiting and accelerating chain reactions, criteria characterizing the chain nature of chemical processes are described. The modern state in the development of the theory of chain reactions is analyzed. The mechanisms describing regularities of formation of molecular products of the chain processes occurring in different systems with the use of different initiators at different conditions are discussed. A summary of the radical-chain character of the radiation sewing of elastomers /non stitched rubbers/ at high pressures (2 GPa) and at temperatures above 300°K is provided and the ionic character of this process at low temperatures (77°K) has been studied. Mechanisms of photolythic and radiolytic processes transformations of any organic pollutants and natural toxins in oxygen-free and oxygen-containing aqueous solutions are proposed. Significant decomposition of natural toxins is observed under influence of ionizing radiation of 60Co source. The short description of the revealed chain processes proceeding in gaseous, liquid, amorphous and solid phases is provided. These studies are an essential contribution to researches in the field of studying of chain chemical processes.Abstract: The history of the formation and development of the theory of chain reactions is briefly presented.
