High-precision integrated explosion protection and detection device

Abstract

The invention discloses a high-precision integrated explosion protection and detection device, which is an integrated device for detecting and determining existence of an explosive by use of a instantgamma-ray neutron activation analysis technology and with an explosion protection function. The device consists of an explosion protection system, a neutron source item system, a sample detection system, an energy spectrum analysis system, a shielding protection system and a mechanical power system, wherein a neutron source is used for activating a characteristic gamma ray of a detected object, adetector is used for gamma ray collection and energy spectrum measurement, the explosion protection system has a relatively good energy absorption cushioning function, the shielding protection systemis used for implementing dose protection over the environment and a human body and reducing harms of neutrons to the environment and the human body, and the mechanical power system has a convenient measurement function. According to the device, a signal to noise ratio is used as a design and evaluation criterion of the device and the whole device is optimized and designed on the basis of a noveldevice evaluation and optimization method, so that the device is endowed with a relatively high signal to noise ratio and the measurement level of the device is improved; in addition, an explosion protection function and a detection function are organically combined, so that the device is high in safety and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of element detection, and in particular relates to a high-precision explosion-proof detection integrated device. Background technique [0002] Public safety has been the focus of attention for a long time. How to effectively detect dangerous explosives in luggage and prevent them from causing harm and panic caused by explosions in densely populated areas is an urgent problem to be solved. In airports, stations and other areas, based on X-ray transmission imaging technology, X-ray machines are used to detect luggage and other items, and judge whether there are dangerous explosives in luggage based on the shape and density information of the detected material. Other technologies also include metal detection. technology, millimeter wave detection technology, etc. In view of the explosion hazard of explosives, explosion-proof barrels and explosion-proof blankets are usually set up to prevent the hazards caused ...
