Description
Technical Field
The invention relates to the field of protective shoes, in particular to a pair of safety protective boots for preventing poison and radiation.
Background
Tritium gas has little harm to the external irradiation of human bodies, and the main harm to the human bodies is the internal irradiation harm of tritium water formed after tritium enters the human bodies. After entering the human body, the tritium water can almost spread in each tissue and organ of the human body, and further generates periodic uniform internal radiation injury. The degree of damage caused by irradiation in tritium water, the chemical form and ingestion mode of tritium and the binding capacity of tritium and human tissues are related. Inhalation and absorption on the surface of human skin during respiration are both routes that a human body may take in tritium gas, and the like. Wherein tritium is inhaled by direct breathing from the mouth and nose, which is the main route of tritium entry into the human body. More than 60% of atoms in the human body are hydrogen, and 5% of them are involved in the metabolic reaction and cell growth of the human body every day. These tritium bound to proteins, lipids and carbohydrates, especially nuclear proteins like DNA, are called organic bound tritium, which presents a heterogeneous distribution in vivo, with a longer residence time in vivo than tritium water, and therefore a correspondingly larger dose. The longer the body is irradiated with tritiated water, the higher the level of organic tritium in the body, until after a long period of irradiation the two establish equilibrium in the body. These unique and significant properties make the radiation hazard of organic tritium also of concern. The protection of tritium cannot be realized by a pure polymer composite material due to the inherent poor gas barrier performance of the polymer material, and tritium beta radiation can break polymer chains to degrade, so that tritium permeation is further increased; the single aluminum oxide tritium-proof material can delay the penetration of tritium in a high polymer material, but has the degradation effect on a high polymer chain by beta radiation of tritium, so that an excellent tritium-proof material is considered from the aspect of retarding the penetration of tritium and shielding the beta radiation of tritium.
