Anti-radiation material for human body safety inspection detector

Abstract

A radiation-proof material for a detecting instrument for safety check of a human body is prepared from, by weight, 12-24 parts of silver fiber, 15-28 parts of ginned cotton fiber, 2-4 parts of poly phenyl siloxane, 5-8 parts of epoxy resin, 1-2 parts of polyethylene, 3-9 parts of silica sand, 3-10 parts of lead oxide, 4-12 parts of copper oxide, 7-15 parts of poly acetate, 1-8 parts of polyolefin, 8-16 parts of polypropylene, 2-5 parts of tributoxyethyl phosphate, 2-4 parts of styrene-butadiene latex, 5-15 parts of ethoxyethanol, 2-6 parts of dimethyl ether, 1-5 parts of barium sulfate, 3-12 parts of fluorine-containing resin, 4-8 parts of nano carbon powder, 5-14 parts of graphite powder and 5-10 parts of aluminum powder.

Description

technical field [0001] The invention relates to the technical field of human body safety inspection detector equipment, in particular to radiation-proof materials for human body safety inspection detectors. Background technique [0002] In recent years, public security issues have increasingly attracted the attention of people all over the world, and higher requirements have been put forward for the reliability and intelligence of anti-terrorism, security detection and public security investigation systems. Common security inspection equipment at home and abroad include metal security doors, hand-held metal security detectors, luggage security detectors, millimeter-wave security detectors, and back-scattered security detectors. They are roughly divided into two generations of products according to their production time and functions: [0003] The first-generation security inspection products are represented by metal security doors and hand-held metal security detectors.

AI Technical Summary

Problems solved by technology

[0003] The first generation of security inspection products are represented by metal security doors and hand-held metal security detectors. This type of equipment detects metal objects through magnetic field technology, and can only detect metal objects, and cannot effectively distinguish and detect non-metal objects.

No imaging system, unable to locate suspicious objects

[0004] The second-generation security inspection products are represented by luggage security detectors, millimeter wave security detectors and back-scattered security detectors. Among them, luggage security detectors use high-dose X-ray irradiation to clearly detect suspicious objects in luggage, which is fast and extremely large. It changed the current situation of security inspection at that time, but with the improvement of criminal methods, this type of equipment cannot be used for human inspection due to dose and design reasons

[0005] At present, the dose of this type of equipment has always been at the safe node of the acceptable dose for the human body, and the electromagnetic radiation of millimeter waves will destroy the bioelectric field of the human body, which will affect heart patients with pacemakers, and there is a huge potential safety hazard

[0006] During the on-site operation, the staff in the security inspection place are faced with long-term contact with the security inspection equipment, and the distance is relatively close, which will cause great harm to the body
