Portable anti-Compton detector

Abstract

The invention relates to the field of ore detection and aims at providing a portable anti-Compton detector. The portable anti-Compton detector comprises an upper electronics unit room and a lower detector room, wherein the top part of the upper electronics unit room is provided with a handle; a main detector is packaged inside the lower detector room; the lower end of the main detector is provided with a window; the periphery of the main detector is provided with multiple anticoincidence detectors; the outer layer of the multiple anticoincidence detectors is provided with a shielding layer; each of the main detector and the multiple anticoincidence detectors comprises a scintillation crystal, an optical coupling material, a photodiode, a preamplifier circuit and a bias power supply circuit; the electronics unit room comprises each unit circuit and a battery; and the unit circuits comprise a summing circuit and multiple analysis circuits with anticoincidence circuits. The anti-Compton detector has the advantages that the structure is simple; the cost is low; and carrying is convenient and easy.

Description

technical field [0001] The invention relates to the field of mine detection, in particular to a portable anti-Compton detector. Background technique [0002] Today, when environmental problems are increasingly prominent and fossil resources are in short supply, it is an important policy for my country's energy construction to actively promote nuclear energy development. The vigorous development of nuclear energy and nuclear power requires that sufficient resources must be ensured from the source. In view of the dual role of uranium resources in national defense and national economic construction, China must have sufficient uranium resources as a guarantee to maintain its international status as a nuclear power. Proving a batch of uranium resources as soon as possible has become a geological front for uranium mines. very urgent task. [0003] At present, in uranium ore prospecting, radioactive prospecting is still the preferred method to find uranium ore, and portable gamma...

AI Technical Summary

Problems solved by technology

[0004] 1. The adaptability to the surface of the detection body is not strong, and it is difficult to obtain ideal data in the field

[0005] 2. The sensitivity is not high enough, and the measurement data stability is poor

[0006] 3. The detection directionality is not strong, and it cannot effectively reflect the underground information of the detection point

[0007] 4. There is a disadvantage of "spectrum drift"

Foreign ORTEC company has launched a "portable" anti-Compton spectrometer, its weight is not less than 100kg, it is only suitable for field use, and the relevant detectors must provide liquid nitrogen cooling, its structure is complex, costly, and heavy , it is not convenient for field workers to easily carry the instrument to test everywhere
