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.
The usage of tungsten alloy radiation cover is not subject to NRC, EPA, or special OSHA regulations, so it has been widely used, such as:
Radioactive source containers
Gamma radiography shields
Source holders for oil well logging and industrial instrumentation
