Effect of Too-Moyun field barite fractional composition on the protection effectiveness against radiation

The chemical, fractional composition of barite of Too-Moyunsky deposit of Osh region of the Kyrgyz Republic is investigated. Based on the results obtained, it is concluded that barite found in the rock dumps of the Too-Moyun deposit can be used as a filler to produce a composite material for protection from radiation. A comparative analysis of the obtained data for particles of barite (50-1500 μm) filler with a mass concentration of 10%, 20%, 30%, 40%, 50% and 60% showed that the experimental results of attenuation of beta and gamma radiation with increasing barite composite thickness its radiation protection ability modified by microscopic excipients barite, increased, which is explained by an increase in the number of scattering centers. The maximum value of the increase in the beta radiation attenuation multiplication in the course of the experiment on the thickness of the protective layer of the composite 2,0 cm was approximately 2 times, and in the case of a composite thickness of 5 cm, the attenuation of the beta radiation was a maximum value, that is 100%. At the same time, gamma radiation at a composite thickness of 2 cm is absorbed 1,3 times, and at a composite thickness of 5 cm, the radiation is completely absorbed.
