Problems solved by technology

[0003] For vehicle-mounted radioactive detection systems, in the prior art, only gamma-ray detectors are generally equipped in the detection system, and gamma-rays are easily shielded by heavy metal materials such as lead, so the detection of shielded gamma radioactive substances is more effective In order to reduce, if gamma ray detection is used in conjunction with neutron detectors, it is more conducive to the detection of radioactive substances

Abstract

The invention belongs to the technical field of radioactivity detection and discloses a vehicle-mounted radioactivity detecting system. The system comprises a carrying device, a neutron detector, a GPS (Global Positioning System), a gamma ray detector, a power and a computer, and is characterized by also comprising a dose rate meter and a portable gamma spectrometer. The system has the advantages of detecting all directions at 360 degrees in a mobile state, directionally detecting in a stationary state, measuring the dose rate simultaneously detecting neutrons and gamma rays.

Description

technical field [0001] The invention belongs to the technical field of radiation detection, and in particular relates to a vehicle-mounted radiation detection system. Background technique [0002] Radiation detection is of great significance to prevent the illegal transfer of nuclear materials or other radioactive substances, and ensure the safety of national security facilities and the public. At present, there are three types of radiation detection equipment: one is a fixed measuring device for personnel, vehicles, containers, etc.; the other is a portable small hand-held radiation detector; [0003] For vehicle-mounted radioactive detection systems, in the prior art, only gamma-ray detectors are generally equipped in the detection system, and gamma-rays are easily shielded by heavy metal materials such as lead, so the detection of shielded gamma radioactive substances is more effective In order to reduce, if the γ-ray detection is used in conjunction with the neutron de...
