Book Description

A total of 418 abstracts from this conference and the complete text of five plenary session papers, as well as 55 abstracts from as All-Union Conference on Radiation Chemistry, have been made available in translation in AEC-tr-2925. Almost all of these papers deal with the actual applications of tracers or radiation in the national economy. The papers presented were divided into three major sections: isotope production and high-intensity gamma systems, technical sciences and industrial uses of isotopes, and biology, medicine, and agriculture. A short summary of the papers as to groups is given. (W.D.M.).

Book Description

The radiation crosslinking of polyethylene, polymethylsiloxane and other polymers was studied. The studies on the mechanism of crosslinking of polyethylene indicate that the crosslinking process takes place mainly as a result of the simultaneous detachment of two hydrogen atoms in neighboring molecules as a result of single primary event. The study of the irradiated polymethylsiloxane has shown that the part of the polymer which crystallizes at -40-50C DECREASES IN PROPORTION TO THE RADIATION DOSE. A comparative study of the process of radiation vulcanization of natural and synthetic rubber was made. It was shown that certain additives retard radiation vulcanization, while others accelerate it somewhat. (Author, modified-PL).
