Novel beta-ray detection device

Abstract

A novel beta-ray detection device disclosed by the present invention solves the problem in the prior art that a conventional beta-ray detection device is narrow in application range and low in detection precision and accuracy due to the large size and the harsh usage conditions. The novel beta-ray detection device of the present invention comprises a beta-ray detection probe, an anti-radiation remote transmission optical fiber, a photomultiplier, a prepositive amplifying and shaping circuit and a PC, is simple in structure, scientific and reasonable in design, high in reliability and accuratein detection data, is convenient to use, and can be used in a closed environment or a high-radiation dose environment. The beta-ray detection probe mainly adopts an inorganic scintillator film material and is plated, thereby shrinking the size of the probe, simplifying the preparation technology of the probe, effectively improving the light extraction efficiency of the scintillator film, being able to convert the radiation information into the optical information effectively while guaranteeing that situation that a scintillator effectively acquires the beta-ray signals.

Description

technical field [0001] The invention relates to a novel beta ray detection device. Background technique [0002] With the continuous development of my country's nuclear power plants and nuclear technology, a large number of nuclides used will cause β-rays in the surrounding environment. If these β-rays leak, they will cause radiation damage to human skin and organs, and cause tissue lesions. Therefore, real-time monitoring of β-rays in nuclear power plants, spent fuel processing plants and other nuclear-related environments is very important. [0003] At present, β-ray detectors mainly include gas ionization chamber detectors, semiconductor detectors and scintillation detectors. Gas ionization chamber detectors generally use gas-filled proportional counters, but relatively speaking, they have low sensitivity, poor thermal stability, and large volume. The semiconductor detector uses the energy loss of the incident electrons in the semiconductor material to generate electron...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a new type of β-ray detection device, which solves the problem that the prior art β-ray detectors are large in volume and harsh in use conditions and are not suitable for detecting small volumes or confined spaces. The β-ray radiation signal collected in the radiation environment becomes weaker, which affects the detection accuracy, and the use of electric wires to transmit radiation information will generate electronic noise in the radiation environment, which affects the accuracy of long-distance transmission of radiation information.
