Container Inspection System
Container inspection or non-intrusive inspection (NII) refers to non-destructive methods of inspecting and identifying goods in transportation systems. It is often used for scanning of intermodal freight shipping containers. Container inspection system is using X-rays and γ-rays to detect the items in containers, airline tray, transport trucks, or freight trains.
The Applications of Container Inspection Tungsten Radiation Shield
Container inspection tungsten radiation shield is usually used in container inspection system as the main components of gamma radiation detectors, gamma radiation detectors, and neutron radiation detectors. Those detectors can be used in ports, prisons, and border, which can detect weather mass destruction weapons, explosives, weapons, drugs and undeclared goods are hiding in the vehicles.
Why Use Container Inspection Tungsten Radiation Shield?
Compared to traditional radiation shielding materials such as lead and boron carbide, tungsten alloy mobile shielding provides 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, and the thickness would be thinner. Tungsten alloy material could be made with thinner thickness but high absorption of radiation in high density. During design of shielding, tungsten alloy radiation shielding 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 tungsten alloy radiation shielding material of the half-value layer values
