Radiation detecting system and radiation inspection method

Abstract

The invention discloses a radiation inspection system and a radiation inspection method using the radiation inspection system. The radiation inspection system has a standard inspection mode and a rapid inspection mode, and comprises a fixed inspection device, wherein the fixed inspection device comprises a vertical view angle inspection device, the vertical view angle inspection device outputs a first radiation scanning ray in the standard inspection mode, and outputs a second radiation scanning ray in the rapid inspection mode; and a moveable inspection device, wherein the moveable inspectiondevice can be moved relative to the fixed inspection device, the moveable inspection device comprises a horizontal view angle inspection device, the horizontal view angle inspection device is moved along with the moveable inspection device in a length direction of a detected vehicle in the standard inspection mode and outputs a third radiation scanning ray, and is fixed in the rapid inspection mode and outputs a fourth radiation scanning ray, wherein the output energy and / or dosage of the third radiation scanning ray is higher than that of the fourth radiation scanning ray. The radiation inspection system is capable of simultaneously considering the penetrability of the radiation detection to the different vehicles and the passing rate of the vehicle.

Description

technical field [0001] The present invention relates to the technical field of radiation inspection, in particular to a radiation inspection system and a radiation inspection method for inspecting vehicles using the radiation inspection system Background technique [0002] Radiation imaging is a technique that uses radiation rays to see inside objects. This technology can obtain information such as the internal structure and density of the object without destroying the object, and has been widely used in medical and health, national economy, scientific research and other fields. Chest x-rays in hospitals and security checks in stations and airports are the most common examples in daily life. In the process of inspection of on-board cargo of vehicles in customs, ports and other places, the use of this technology can realize the inspection of goods without opening the box, which improves the inspection efficiency. In order to reduce the radiation impact on vehicle drivers, t...

AI Technical Summary

Problems solved by technology

In order to reduce the radiation impact on vehicle drivers, the radiation energy or dose of the radiation source is limited to a certain extent, but for heavy-duty cargo, low-energy or dose radiation scanning inspections may have problems such as the radiation cannot penetrate, so it is necessary to ensure certain Radiation energy or dose to improve the accuracy of the examination
