The method and the system are characterized in that a power supply device provides an operating voltage for the monitoring system; a boosting device, a sampling device, a measuring device and a sample transmission device transmit respective status signals to an upper computer through a driving and status feedback module, the upper computer controls the boosting device to cooperate with the sampling device through the driving and status feedback module so as to sample environmental airborne radioactive substances, and samples are transmitted to the measuring device through the sample transmission device; the upper computer controls the boosting device to match with the measuring device through the driving and status feedback module so as to measure alpha-ray particles and gamma decay photons released by the samples to obtain analog pulse signals, the analog pulse signals are transmitted to a signal preprocessing unit for processing to obtain alpha and gamma measurement spectral lines, and the spectral lines are transmitted to the upper machine; the upper computer calculates to obtain activity concentration of the sampled environment, and displays, stores and transmits the activity concentration to a central processor.

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, ...
