A continuous monitoring method and monitoring system of α and γ dual-channel energy spectrum

Abstract

The invention relates to a continuous monitoring method and monitoring system of double-channel energy spectrum of α and γ, which is characterized in that: the power supply device provides the working voltage for the monitoring system; The feedback modules transmit their status signals to the host computer, and the host computer controls the pressure-lifting device through the drive and status feedback module to cooperate with the sampling device to sample the ambient airborne radioactive substances, and the collected samples are transmitted to the measuring device through the sample transmission device; the host computer passes The driving and state feedback module controls the pressure-lifting device and cooperates with the measuring device to measure the α-ray particles and γ-decay photons released by the sample, obtain the analog pulse signal and transmit it to the signal pre-processing unit for processing, and obtain the α and γ measurement spectral lines and It is transmitted to the host computer; the host computer calculates the radioactivity concentration of the sampling environment, displays, stores and transmits it to the central processing unit.

Description

technical field [0001] The invention relates to a monitoring method and monitoring system for environmental airborne radioactive substances, in particular to a continuous monitoring method and monitoring system for α and γ dual-channel energy spectrum. Background technique [0002] In the process of nuclear industry production and testing, radioactive substances may be released. They use the atmosphere as a carrier to form radioactive aerosols and diffuse into the environment. Due to their high ionization effect, low concentration, and easy electrification of particles, they are the cause of internal exposure of the human body. Key factor. Radioactive aerosol monitoring is an important part of nuclear environmental protection, which is of great significance for protecting environmental safety, timely discovering abnormal radioactive leakage, and emergency response to nuclear accidents. In recent years, with the enhancement of people's awareness of environmental protection, ...

Problems solved by technology

However, due to the statistical fluctuations of radioactive measurement lines, it is necessary to accumulate a certain measurement time to ensure the accuracy of the analysis results, which leads to the lag of the nuclear spectrum data processing results, resulting in a time monitoring blank area
