Today, when nuclear energy is widely used, nuclear safety is of paramount importance, and nuclear emergency monitoring equipment is a key line of defense in guarding this safety. Such equipment plays an indispensable role in preventing nuclear accidents and responding to nuclear emergencies.

Working principle: multi-dimensional precision detection

Nuclear emergency monitoring equipment mainly uses a variety of detection techniques to identify and measure radiation. Among them, the ionization chamber detector makes use of the characteristic that radiation can ionize the gas. When the radiation particles enter the ionization chamber, the gas molecules will be ionized to produce electron-ion pairs, which will form a current signal under the action of the applied electric field, and the radiation level can be known by measuring the current strength. Scintillation detectors utilize scintillators that emit fluorescence when excited by radiation, which is then converted into an electrical signal by a photomultiplier tube to detect radiation and differentiate between different types of radiation particles based on signal characteristics.

Importance: Protecting nuclear safety

They are the “guardians” of the daily operation of nuclear facilities, real-time monitoring of radiation background levels, timely detection of potential radiation anomalies, early warning of possible problems. In nuclear emergencies, they are the “scouts” of emergency response, quickly and accurately determining the radiation dose rate, radionuclide species and other key information, providing a scientific basis for emergency decision-making, helping rescuers to develop reasonable protection and countermeasures, and minimizing the hazards of radiation on personnel and the environment.

Application Scenario: Comprehensive Coverage for Safety

In the vicinity of the nuclear power plant, the nuclear emergency monitoring equipment forms a tight monitoring network, which carries out all-round monitoring of the air, soil, water, etc. in the environment to ensure that the operation of the nuclear power plant will not cause radiation contamination to the surrounding environment. During the transportation and storage of nuclear waste, corresponding monitoring equipment will also be equipped to monitor the radiation situation along the transportation routes and at the storage sites in real time, so as to prevent nuclear safety accidents caused by the leakage of nuclear waste. In addition, in some scientific research institutions and industrial enterprises involving the use of radioactive substances, nuclear emergency monitoring equipment also plays an important role in ensuring the safety of staff and the surrounding environment.

With its powerful functions and accurate detection ability, nuclear emergency monitoring equipment has woven a solid protective net for nuclear safety, and with the continuous development of technology, it will play a more important role in guarding the road of human nuclear safety.
