Abstract

The invention relates to a method, device and system for inspecting an object based on a cosmic ray, and belongs to the technical field of radio imaging and safety inspection. The method comprises the steps: recording the movement track of an inspected object through the record of monitoring equipment; obtaining the information of charged particles in the cosmic ray through employing a position sensitivity detector, wherein the information of the charged particles comprises the track information of the charged particles; carrying out the position according of the movement track and the track information, and determining the object; carrying out the track remodeling of the charged particles according to the information of the charged particles; and recognizing the internal material of the movement object according to the track remodeling. The method inspects a moving person, and can detect a nuclear material, narcotics and explosives carried by the person.

Description

technical field [0001] The present invention relates to radiation imaging and safety inspection technology, in particular to a method, device and system for inspecting objects based on cosmic rays. Background technique [0002] With the rapid development of nuclear energy and nuclear technology, the technical threshold for nuclear weapon preparation is getting lower and lower. According to the regulations of the International Atomic Energy Agency, the purity of uranium 235 or plutonium 239, the raw material of nuclear bombs, reaches 92-93%, which is called weapon grade, that is, reaching a certain amount (generally 12-16kg of uranium and 6-9kg of plutonium) can cause a nuclear explosion. The powerful destructiveness of nuclear weapons not only brings huge economic losses, but also seriously threatens the survival and development of human beings. [0003] On the other hand, the criminal incidents and economic losses caused by the illegal proliferation of explosives and drugs...
