Tungsten Alloy Nuclear Radiation Shielding

Nuclear radiation, also known as ionizing radiation, is the microscopic particle flow released from the transition process of atomic nucleus (from an energy state of a structure or a structure into another energy state or another structure) that can cause the ionization or excitation in materials. Nuclear radiation is mainly produced by nuclear reactions, or released from fission products. Nuclear explosions and nuclear accidents will also generate nuclear radiation, including α, β and γ three kinds of rays. Nuclear radiation can cause harm to human body, while the sensitivity of the somatic and germ cells of the body to nuclear radiation and the damage effects of them are different. Once somatic cells are damaged, can lead to diseases in the organ tissues and ultimately death, and the damaged cells will not be transferred to the next generation after the death of the body cells; while once reproductive cells are damaged, the next generation will inherit the parent‘s changed gene, so that leads to defects in the offspring.

Radioactive substances of the nuclear radiation include iodine 131 and cesium 137, which can enter the body through breathing, skin wounds and gastrointestinal absorption, causing internal radiation. Once iodine 131 enters the human body, it can cause thyroid disease; while Cs-137 will damage the body's blood system and the nervous system after it entering the human body, therefore nuclear radiation must be avoided by humans. γ radiation can also penetrate a certain distance to be absorbed by the body, and cause radiation damage. Symptoms of radiation sickness caused by internal and external radiation include hair loss, leukemia, bleeding, vomiting, fatigue, skin redness, dizziness, insomnia, ulcers, diarrhea. Sometimes internal and external radiation will increase the incidence of distortion, cancer, hereditary disease, and affect the health of future generations. In general, the more radiation energy received by the body, the more serious their symptoms of radiation sickness, and the greater the risk of carcinogenic, teratogenic.

Tungsten alloy nuclear radiation shielding is a tungsten alloy shielding with excellent radiation shielding performance, high temperature resistance and strong applicability. Lead is used as a shielding material early, but its shielding effect is not as good as the tungsten alloy shielding. Tungsten alloy shielding is the best choice. Due to the high density of tungsten alloy shielding, its shielding effect is twice that of lead. In addition, lead and its compounds are toxic and dangerous to human health，while tungsten alloy shielding is harmless non-toxic, will not cause harm to human health.
