PATTERNS AND MECHANISMS OF INTERACTION OF RADIOACTIVE CARGO RADIATION WITH METAL-GLASS LAYER OF WATERCRAFTS STRUCTURE

Abstract

The article discusses the use of new metalglass ma terials and coatings with steel and aluminum matrix, filled with hollow glass microspheres, as the structures protective layer of floating constructions which serve as transshipment and temporary storage points of radioactive substances of low and medium activity. The purpose of work is to establish patterns, to investigate processes and mechanisms of interaction of ionizing radiation with a protective metalglass layer. The protective layer can be formed in plates by hot pressing method and with the help of radiationresi stant adhesives can be attached to the surface of structures; it is also possible to form it by electricarc spra ying. The work represents a set of theoretical researches based on modeling of interaction of ionizing radiation with the structural elements of metalglass compositi ons, and contains new scientific information about patterns and mechanisms of formation of the protective properties. As an experimental evaluation criteria was adopted the mass attenuation coefficient of Xray radiation , which characterizes the maximum protective ability of materials at their minimum density. The comparison of Xray protective properties with other kinds of syntactics and coatings filled with solid particles of sodiumsilicate and leadcontaining glass showed that the propertie s of the metalglass compositions are not inferior to counterparts. The research results can be used in structures designing of floating constructions for transportation of radioactive materials.
