Unattended radioactive contamination monitoring apparatus

Abstract

The invention discloses an unattended radioactive contamination monitoring apparatus which includes a plastic scintillator, a sodium iodide detector, an automatic control device, a remote online monitoring terminal, a water suction pump, a filtering net, a first valve, a second valve, a water tank and a water storage tank, wherein the automatic control device includes a MCU module, a power module, a wireless communication module and a GPS module, and the sodium iodide detector includes a sodium iodide liquid detector and a sodium iodide gas detector. The power module, the wireless communication module, the GPS module and the sodium iodide detector, the first valve and the second valve are respectively connected to the MCU module; the sodium iodide liquid detector is arranged inside the water tank which is provided therein with a water gauge. The monitoring apparatus can operate automatically, and features in low power consumption, intelligence and having no requirements for personnel attendance. For river upstream and downstream areas in remote regions where mainland nuclear stations are often located, the monitoring apparatus can perform multi-point deployment and control and help the monitoring method to go forward and networked.

Description

technical field [0001] The invention relates to a pollution monitoring device, in particular to an unattended radioactive pollution monitoring device. Background technique [0002] After the "3.11 accident" in Fukushima, Japan, considering natural disasters (such as typhoons, tsunamis and earthquakes), water intake conditions, national defense and social factors, the current coastal nuclear power plants can no longer meet my country's current energy diversification development strategy. Under the adjustment of China's energy strategy, the development of inland nuclear power plants will become an inevitable choice. At present, inland nuclear power plants are usually located on remote riversides far away from the city. Once a nuclear leakage accident occurs, with the spread of atmospheric dust, river water flow and soil infiltration, radioactive materials will have a devastating impact on the ecological environment around the nuclear power plant. hit. The routine inspection ...

AI Technical Summary

Problems solved by technology

The routine inspection technology of radionuclides in water and the atmosphere is usually on-site sampling, and the samples are sent to the laboratory for analysis. Although this method can analyze specific nuclides that exceed the standard, the required sampling and inspection cycle is long and cannot be timely. feedback data
