Reaction of Spot Radioactive Source with the Energy of 661.7 KeV on the Modification in the Structure of Surface Layer of Metal Composite Material

Abstract

This paper presents the results of studies of the composite metal radio-protective building material by method of atomic-force probe microscopy, before and after its irradiation with gamma rays of 661.7 keV and absorbed dose up to 2 MGy. Composite metal material is based on the filling of hematite iron ore concentrate and aluminum matrix. This composite material has high technical (physical and mechanical) and radio-protective proprieties. The composite is planned to be employed as a bearing structure at various nuclear facilities.

“…The filling material can be of any nature both in a kind mono component, and it can also be in the form of several components combining unique properties, such as the systems filler [1][2][3][4][5][6][7][8]. These materials also include composites with intermetallic inclusions; bituminous materials; materials on ceramic, polymeric, elastomeric, bituminous bases, with adding of the titan, iron, molybdenum, lead, magnesium, aluminum and other elements and oxides, as well as other materials and composites possessing the radiation-protective properties [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. Those materials are itself an irreplaceable component of the human activity field which aims and purposes they were developed for.…”
