Nuclear radiation emergency detection system, detection method and self-starting controller thereof

Abstract

The invention discloses a nuclear radiation emergency detection system, which relates to the technical field of radiation measurement. The detection system comprises a nuclear radiation self-startingcontroller and a fixed field radiation dose collector. When nuclear leakage does not happen to a to-be-detected nuclear power station, the nuclear radiation self-starting controller is in a working state, and the fixed field radiation dose collector is in a standby state; when nuclear leakage happens to the to-be-detected nuclear power station, the nuclear radiation self-starting controller startsand the fixed field radiation dose collector works, and the nuclear radiation information in the environment is acquired. The nuclear radiation self-starting controller and the multipoint multi-rangefixed field radiation dose collector are combined, real-time monitoring on the diffusion range, the intensity and nuclide types of radioactive substances in the case of nuclear leakage can be realized, and due to the design of automatic starting, the power consumption of the power supply is reduced, and the maintenance cost is reduced. The invention also discloses a nuclear radiation emergency detection method and a nuclear radiation self-starting controller.

Description

technical field [0001] The invention relates to the technical field of radiation measurement, in particular to a nuclear radiation emergency detection system, a detection method and a self-starting controller thereof. Background technique [0002] Once a nuclear power plant leaks, the resulting radiation accident will cause great casualties, environmental pollution and huge economic losses. According to statistics, from 1952 to 1986, there were as many as 36 serious accidents and accidents caused by foreign research reactors and power reactors. Loss. Due to the suddenness of nuclear radiation and its huge social impact, if we can detect and understand the scope of the nuclear leak, the specific number of kilometers, and the radioactive intensity at the first time of the nuclear leak, we can make timely and accurate decisions on emergency behavior. Providers with information on nuclear radiation leakage, so that workers can be safely evacuated, the scope of leakage can be c...

Problems solved by technology

[0005] The current fixed radiation monitoring system, because the site is fixed, if it is monitored in real time for a long time, the maintenance cost is high and the energy consumption is large

And the fixed phase detector can only realize small-scale radioactive monitoring
