Abstract

The invention discloses a regional portable multi-terminal gamma ray monitoring system. The system comprises a detection module, a data acquisition and processing module used for acquiring an electricpulse signal output by a detection module and analyzing and processing the electric pulse signal, and a wireless communication module used for being in communication connection with an upper computer, wherein the detection module includes a scintillator, a photoelectric conversion element and a signal reading circuit, and the scintillator is used for receiving gamma rays and generating visible light; the photoelectric conversion element is used for converting visible light into an electric pulse signal; and the signal reading circuit is used for outputting the electric pulse signal, the scintillator is a yttrium silicate scintillation crystal or a lutetium yttrium silicate scintillation crystal, and the photoelectric conversion element is a silicon photomultiplier. According to the monitoring system, radiation position information, radiation intensity information, nuclide type information and the like can be transmitted to the upper computer through the wireless communication module for big data carding; and portability and miniaturization are achieved by optimizing the scintillator and the photoelectric conversion element, and high detection efficiency is possessed.

Description

technical field [0001] This application generally relates to the technical field of nuclear radiation detectors, and specifically relates to a regional portable multi-terminal gamma ray monitoring system. Background technique [0002] Portable gamma ray dosimeters are widely used in personal protection, safety inspection, environmental protection and medical and health fields, and can provide timely and accurate information on environmental radiation intensity and other information to staff. [0003] Traditional portable environmental radiation dosimeters mainly use detectors such as GM tubes, high-voltage ionization chambers, thallium-doped sodium iodide NaI scintillators, and plastic scintillators. Among them, the GM tube is the most widely used, but because of its short service life, low sensitivity, and large statistical fluctuations, it is rarely used as an accurate measuring instrument. Due to its simple structure, stable working performance and long service life, hig...
