A New Type of Nuclear Radiation Protection Structure and Its Application

Abstract

The invention provides a novel nuclear radiation protection structure and its application, comprising an outer layer, a complex wetting layer, an activated carbon fiber layer 1, a modified activated carbon layer and an activated carbon fiber layer 2, and the outer layer and the complexing wetting layer There is a gap, and the complex wetting layer, activated carbon fiber layer 1, modified activated carbon layer and activated carbon fiber layer 2 are successively laid adjacently; It is a solution prepared by complexing agent Ⅰ, glycerol and deionized water; the modified activated carbon layer is the activated carbon particle layer impregnated by complexing agent Ⅱ, and the activated carbon particle layer is formed by filling the activated carbon particles. The present invention adopts this structure, which can realize good adsorption of small particle aerosol and radioactive iodine in the gas, and can be complexed with various radioactive metal nuclides, so as to play a double adsorption role and effectively prevent radioactive iodine from entering the human body through breathing , to avoid the formation of internal radiation damage to human health.

Description

technical field [0001] The invention relates to the technical field of nuclear radiation protection, in particular to a novel nuclear radiation protection structure and its application. Background technique [0002] In places such as uranium ore mining sites and uranium processing plants, nuclear power plants, and units using nuclear reactors, nuclear leakage and radioactive material storage accidents will cause long-term environmental pollution (for example: the half-life of uranium-235 is 700 million years; the half-life of cesium-137 is 30 years; the half-life of strontium-90 is 30 years; the half-life of plutonium-238 is 86 years), and the scope of influence is large. Short, but highly toxic and has serious effects on the thyroid. The impact of nuclear leakage on personnel in general is manifested in nuclear radiation and aerosols carrying radioactive substances (aerosols smaller than 0.1 μm do Brownian motion and do not settle; aerosols between 1-10 μm settle slowly an...
