Lemeshev M. Radioprotective cover of betel-m

The object of the research is metal saturated electric conductive concrete based on mineral binder (betel-m); the aim of the research is to work out radio- protective materials (radio- screen and radio- absorptive) for electric magnetic radiation protecting in extremely high frequency range made of betel-m and obtaining efficient radio- absorptive cover based upon them; the innovating is working out of radio-absorptive based on radio-screeen and radio-absorptive types of betel; the methods of the research and the equipment are analytical, experimental, specially assembled research equipment; the theoretical and practical results are the obtaining of radio- screen metal- saturated types of dense structure concrete are proved and the radio- absorptive ones of porous structure; as the result the radio- absorptive covering of varying structure made of betel-m has been obtained; they provide radio- absorbency in extremely high frequency range till 85 dB with the reflection coefficient 17%; the range of implementation is within the branch; the branch of using is building.
