Gamma ray detection system with composite structure shell

Abstract

The invention discloses a gamma ray detection system with a composite structure shell. The gamma ray detection system comprises detection equipment. The detection equipment comprises a shell, a sensor, a control PCB (printed circuit board) and a display terminal. The APP software is arranged in the display terminal. The detection equipment is connected with the APP software in the display terminalin a wireless communication mode. The sensor comprises a shielding cover, a scintillation crystal unit and a pulse amplifier both arranged in the shielding cover. The pulse amplifier is electricallyconnected with the scintillation crystal unit. The pulse amplifier is electrically connected with the control PCB. The shell is of a composite structure composed of a thermoelectric material layer andan insulating layer. According to the gamma ray detection system, the composite structure shell composed of the thermoelectric material layer and the insulating layer is adopted, and the self-electricity generation function is achieved. The endurance time of the detection equipment can be prolonged.

Description

technical field [0001] The invention relates to a gamma ray detection system, in particular to a portable gamma ray detection system which adopts a composite structure shell formed by a pyroelectric material layer and an insulating layer. Background technique [0002] Ionizing radiation refers to the general term for all radiation that can cause ionization of matter. There are many types, such as high-speed charged particles including α particles, β particles, and protons, and uncharged particles including neutrons, X-rays, and γ-rays. Common ionizing radiation includes: transmissometers in hospitals, energy spectrometers in laboratories, mineral marble used in home decoration, various radioactive sources in industry, nuclear industry waste, patients receiving radiation therapy, nuclear power plants, and rays from the universe. The ionizing radiation mentioned above mainly refers to neutron, X-ray, and gamma-ray radiation with strong penetrating power and great harm. Ionizi...

Problems solved by technology

The Geiger counter tube of the Geiger counter is large in size and needs to provide an additional high-voltage power supply of hundreds of volts or even thousands of volts. The realization of this high-voltage power supply requires a large space and has potential safety hazards. In short, the principle of the Geiger counter Although mature, it is not suitable for wearable and portable ionizing radiation detectors; the cost of semiconductor counting is high, and it is suitable for use in high-end energy spectrum analysis instruments

[0004] Wearable and portable gamma ray detection systems are generally powered by built-in batteries or external power sources. However, when there is no external power source and the built-in battery is insufficient, the detection equipment cannot continue to work.
