Classification and introduction of radiation detectors
Sensor devices, devices or materials used to observe and study the microscopic phenomena of nuclear radiation and particles. The working principle of radiation detectors is based on the interaction of particles with matter.
Radiation detector classification:
The ways that radiation detectors give information are mainly divided into two categories: one is that after the particles are incident on the detector, the information that can be accepted by people's senses is given after a certain treatment. For example, various particle track detectors generally go through processes such as photography, development or chemical corrosion. There are also thermoluminescence detectors and photoluminescence detectors, which can only give light output related to the amount of irradiation after thermal or optical excitation. This type of detector basically does not belong to the research scope of nuclear electronics. Another type of detector immediately gives the corresponding electrical signal after receiving the incident particle, which can be recorded and analyzed after being amplified and processed by the electronic circuit. This second category may be referred to as electrical detectors. Electrical detectors are the most widely used radiation detectors. The advent of this type of detector has led to the emergence and development of a new branch of nuclear electronics.

In the past ten years, a variety of new nuclear radiation detectors have been successfully developed, some of which have become commodities and are gradually accepted by the market; some detectors have been eliminated or gradually replaced; some "old" detectors Recognized and reused.
