Embodiment Construction

[0022] The radioactive material orientation detection device according to the present invention will now be further described with reference in detail to illustrative, non-limiting embodiments of the present invention.

[0023] See attached figure 1 -3. A radioactive substance orientation detection device according to the present invention can be used to detect the existence of radioactive substances and determine the location of radioactive substances in places where radioactive substances (ie radioactive sources) are suspected to exist. The radioactive material orientation detection equipment includes: a first ray detection device 1; a second ray detection device 3, the type and parameters of the second ray detection device 3 and the first ray detection device are the same, such as X-ray detectors, gamma-ray detectors. In the following first embodiment of the present invention, a plastic scintillator detector for detecting gamma rays is taken as an example to illustrate the...

Abstract

The invention discloses a radioactive material direction detection device, for searching and positioning radioactive materials, which comprises: at least one first ray detection device; at least one second ray detection device, while each second detection device and is parallel and coupled arranged with each first ray detection device, the detection surfaces of the first and the second ray detection devices are in one plane, for receiving the rays from one direction via same method and respectively generating a first detection signal and a second detection signal; a ray shield plate which is arranged between the coupled first and second ray detection devices and extends vertically to the front side of the detection surfaces; and a judgment device for receiving the first detection signal and the second detection signal of the first and the second ray detection devices, to judge the existence of radioactive materials according to the first and the second detection signals and determine the direction of the radioactive material according to the difference between the first and the second detection signals. The invention further provides a radioactive material direction detection method.

Description

technical field [0001] The present invention relates to a device and method for locating radioactive materials, in particular to a hand-held radioactive material locating detection device and its detection method, which can not only detect the existence of radioactive sources, but also provide The approximate orientation information is helpful for quickly and accurately determining the location of unknown radioactive sources. The hand-held radioactive material orientation detection device and its detection method of the present invention can be applied to any occasion where the orientation detection of radioactive materials is required, such as customs ports, nuclear physics laboratories, nuclear power plants, nuclear waste burial sites or storage warehouses, hospitals, weapons, etc. Manufacturing plant etc. Background technique [0002] Various traditional portable and handheld radioactive material detection equipment are based on a plastic scintillator detector or a 3 Th...
