FIELD: chemistry.
SUBSTANCE: invention relates to decorative construction materials designed for protecting equipment and people in medical, industrial, scientific, administrative and residential facilities from the effect of ionising radiations. The dry construction mixture contains the following in wt %: caustic magnesite powder 10-15, barite concentrate 80-89, modifying additive 0.1-0.5, natural modification schungite III mineral - the rest. The invention is developed in subclaims.
EFFECT: design of material which provides efficient protection from gamma-radiation with reduction of the thickness of protective material and improvement of construction properties of the material at the same time.
