Radiation-induced processes

Oxygen plays a major role in radiation-induced processes. If it is either present during irradiation or admitted to the substance after irradiation, another type of reactive species may arise—a peroxide. Peroxides are usually fairly stable at moderate temperatures and accumulate in the system to a certain extent. They are easily decomposed at elevated temperatures moreover, they are selectively decomposed on further irradiation. 

The authors of this book started working on chemical kinetics more than 10 years ago focusing on investigations of particular radiation - induced processes in solids and liquids. Condensed matter physics, however, treats point (radiation) defects as active particles whose individual characteristics define kinetics of possible processes and radiation properties of materials. A study of an ensemble of such particles (defects), especially if they are created in large concentrations under irradiation for a long time, has lead us to many-particle problems, common in statistical physics. However, the standard theory of diffusion-controlled reactions as developed by Smoluchowski...

Radiation-induced processes at solid-liquid interfaces are of significant importance in many applications of nuclear technology. In water-cooled nuclear reactors, ionizing radiation induces reactions in the water as well as in the interface between the coolant and various system surfaces such as the reactor vessel and the fuel cladding. These processes will directly or indirectly influence the performance as well as the safety of the reactor. In nuclear fuel reprocessing, the significance of radiation-induced interfacial processes is even more obvious. Many countries plan to store spent nuclear fuel in deep geological repositories.

In summary, polysilane derivatives constitute a new class of radiation-sensitive materials for which a number of new applications have appeared. Much of the interest has centered around their unusual electronic properties and their sensitivity to various types of radiation. The nature of these radiation-induced processes is very complex, and although some progress has been made recently in understanding these processes, this area remains a fertile field for future study.

In this scheme, a functionality that does not react with a silylating reagent is converted to a reactive group to incorporate Si selectively in the exposed area, or conversely, a reactive functionality is rendered inert by a radiation-induced process so that Si is selectively introduced in the unexposed region.
