Tungsten Alloy Radiation Room


Our tungsten alloys are used for radioactive source containers, gamma radiography, shields, and source holders for oil-well, logging, and industrial instrumentation. High-density tungsten alloys also serve as collimators and radiation shielding in cancer therapy, as well as syringe protection for radioactive injections. When you need to direct a specific amount of radiation to a targeted area, tungsten alloy radiation room provides the control you need. Luke’s Metals’ high-density alloys will continue to perform, even under extreme, high-heat conditions.

Gamma radiation and X-rays are absorbed most effectively by high-density materials. AT&M high-density materials are a family of tungsten alloy materials with densities 50% greater than that of lead. The high-density, good mechanical strength and excellent mach inability of AT&M materials make them ideal for shielding applications. A variety of sizes and shapes are available. 
Why use tungsten alloy radiation shielding?
Compared to traditional radiation shielding materials such as lead and boron carbide, tungsten alloys provide excellent density with small capacity. At the same weights high density alloy can provide the same energy absorption as lead using 1/3 less material. 

When the weight is certain, more density, more denser, and the thckness would be thinner. Tungsten alloy material could be made with thinner thickness but high absorption of radiation in high density. That is why tungsten alloy material is suitable for raidation shielding.
During design of shielding, it is calculated according to requirements of shield to abate the multiple shielding materials’ thickness.
Formula: K = e0.693 d /
1/2
K: Shield weakened multiple
1/2: The shielding material of the half-value layer values
d: Shielding thickness, with the half-value layer thickness of their units, you need to half-value layer thickness of the quality of translation into the thickness of the material, divided by the density of the material can be obtained.
