Tungsten Alloy Shield Principle

Shield radiation and rays are essential for some workers, especially those who work in the circumstance that full of radiation or rays.

The principle of shielding protection is that the radiation will be weakened when penetrating some materials. Certain thickness of the shielding material can reduce the radiation intensity, put a shield that is thick enough between the radiation source and the body (tungsten alloy shield) can reduce the radiation Level, so that to ensure personal safety.

Shielding main point is to place a shielding material that effectively absorbs radiation between the ray source and the human body. Tungsten alloy shield principle is: the ionizing radiation shielding is achieved by the material of tungsten heavy alloy shield. The absorption of radiation by the material is carried out in the following two ways: energy and particle absorption.

Tungsten alloy shields have a good shielding effect on radioactive materials because tungsten alloy has high density. It is found that the high density properties of the metal have a good shielding effect on the radiation, and the higher the metal density is, the better the shielding effect is. Therefore, tungsten alloy shield has a good shielding effect.
 
The density of lead and tungsten alloys is relatively large. Lead was used earlier, but it exposed some problems in the long-term use. Lead itself and its compounds are toxic to the tissues of the human body, poisoning through the respiratory tract inhalation of its vapor or dust, and then the respiratory tract phagocytic cells to quickly bring it to the blood; or absorbed by the digestive tract, into the blood circulation. Currently, tungsten alloy shield has replaced lead and gradually eliminates the use of lead. It generally uses tungsten heavy alloy to produce shield products, for it has high density and no poison, which is environmental friendly. The tungsten itself is not toxic and does not produce radioactive material. And tungsten alloy is rich and easy to process.
