The Advantages of Tungsten Alloy Shield Compares to Lead Shield

Tungsten alloy shield is used to shield the radioactive material, thus making a shielding device to avoid radiation damage. The main advantage of using a tungsten alloy shield  compared with being made ​​of lead :

1: The greater tdensity,and the better radiation ability. 11.34 density is the density of lead, tungsten alloy density is 16.5 to 19.0.

2: Non-toxic and more environmentally friendly. Lead itself and its compounds are toxic to human tissues, is likely to cause heavy metal pollution in the course of heavy metal poisoning, will produce secondary bremsstrahlung. The tungsten alloy tungsten itself is not toxic and will not output radioactive substances, environmentally harmless.

3:Rich reserves of tungsten, tungsten alloy and relatively easy processing.

4: Thickness small. The same shielding effect, the thickness of the tungsten heavy alloy is only two-thirds of the lead.
