As the name implies ,tungsten alloy shielding for security inspection equipment is used for shielding radiations generated by various security inspection equipments. Security inspection equipment, also known as x-ray security inspection system,is an electronic equipment checking baggage by means of delivering the baggage to check channel through conveyor belt. Its  checking objects include luggage and parcels, large and medium-sized suitcases and bag, consignments. Security inspection equipment is mainly used in railway stations, bus stations, airports, customs, logistics and other important places.

The security inspection equipment uses the X-ray scanning imaging technique , which is the same as that of medical diagnostic X-ray equipment. When the baggage is sent into the X-ray check channel,it will block the detection sensor, so that the detection signals would be sent to the system control part to generate X-rays trigger signals for triggering the X-ray source emits X-ray beam. Collimated X-ray beam passes through the detected goods on the conveyor belt and could be absorbed by the objects, and finally bombards the dual energy semiconductor detector installed in the inspection passage. The X-rays then are transformed into signals by detector, these weak signals are amplified and supplied to the signal processor for further processing. Because X-rays belong to the class of harmful rays, so with the widespread use of security inspection equipment, the tungsten alloy shielding for security inspection equipment also gradually being taken seriously.

The tungsten alloy shielding for security inspection equipment could shield radiation generated by security inspection equipment in a high degree, so as to avoid them doing harm on the security personnel and passengers. Compared to traditional radiation shielding materials such as lead and boron carbide, tungsten alloy shielding provide excellent density with small capacity. Tungsten alloy could be made with thinner thickness but high absorption of radiation in high density.
