Anti-radiation casing of detecting instrument for human body safety check

Abstract

The invention discloses an anti-radiation casing of a detecting instrument for human body safety check. The anti-radiation casing comprises an external layer, an external middle layer, an internal middle layer and an internal layer, wherein the internal middle layer and the internal layer cling to each other, and are pressed closely to form an integral layer; the external middle layer covers the internal middle layer in a detachable manner; the external layer covers the external middle layer in a detachable manner; the external layer is an all-silver fiber knitted fabric layer, the all-silver fiber knitted fabric layer is a composite fiber formed by the fusion of silver ions and an ordinary fabric, and has the advantages of good air permeability, bacterial resistance, capability of eliminating static electricity and stable shielding performance with an anti-radiation shielding value of not lower than 70DB; the external middle layer is a deep sea sediment fabric layer, the deep sea sediment fabric layer is a fabric layer formed by spinning a metal fiber or silver fiber material that is developed by means of a deep sea sediment technology and a lint cotton fiber with a micronaire value of 4.1-4.3 in a mixed manner, and an effective radiation shielding value of the deep sea sediment fabric layer is not lower than 80DB.

Description

technical field [0001] The invention relates to the technical field of human body safety inspection detector equipment, in particular to a radiation-proof shell of a human body safety inspection detector. 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
