Abstract

The invention discloses an environmental gamma energy spectrum continuous monitoring system. The environmental gamma energy spectrum continuous monitoring system comprises a detector for detecting rays and a terminal for displaying and controlling, wherein the detector comprises a housing, a probe arranged in the housing and an electronic system. The probe comprises a shielding housing, a spectrum stabilizing device, a detecting element, a light guide element, a photomultiplier and a front amplifying circuit. The electronic system comprises an amplifier, a multi-channel analyzer, a controller, a memory, a high-voltage power supply and a low-voltage power supply. A NaI (Tl) crystal or LaBr3(Ce) crystal with high sensitivity and high resolution is taken as the detecting element, a substance which internally contains potassium, uranium and thorium automatically stabilizes spectrum, is high in spectrum stabilizing speed and high in precision. The environmental gamma energy spectrum continuous monitoring system is internally provided with a natural radioactive substance to automatically stabilize spectrum, high in sensitivity, good in resolution, used for continuously monitoring yield of the environmental gamma air absorber and can be used for analyzing and identifying gamma nuclide in the environment.

Description

Technical field

[0001] The invention belongs to the field of radiation detection, and specifically relates to an environmental gamma energy spectrum continuous monitoring system for measuring environmental X and gamma radiation. Background technique

[0002] Environmental radiation dose rate monitoring is an important aspect of environmental monitoring. Real-time monitoring of X and γ-ray (hereinafter referred to as radiation) radiation dose rates in the atmospheric environment is carried out through the monitor, to obtain changes in the intensity of radioactive substances in the atmospheric environment, and to monitor the atmospheric environment. Abnormal changes in radioactive materials provide a basis for environmental assessment and accident alarms. Traditional environmental radiation dose rate monitors mainly use two types of nuclear radiation detectors, GM tube and high-pressure ionization chamber. Among them, the GM tube is rarely used as an accurate measuring instrument ...
