The use of gas chromatography for the determination of radiolytic molecular hydrogen, the detachment of which initiates secondary phenomena in the radiation modification of polymers (in English)

Polimery 2019, No 10, 697

Summary

The paper summarizes long-term research into the radiolysis of polymers. The starting point in all cases was the preliminary determination of the radiolytic efficiency of hydrogen evolution. This value is approximately proportional to the number of radicals arising as a result of irradiation, which determines post-radiation phenomena. It was not about accurately describing the radiolysis of a specific polymer, but about paying attention to the benefits of starting the study o fradiolysis from the analysis of hydrogen evolution. The Table 2 gives specific hydrogen yields for selected polymers. The results of these studies were used in the planning of the radioactive waste repository in Los Alamos National Laboratory.
