Description

Technical Field

[0001] The utility model belongs to the technical field of radiation detection, and in particular relates to a portable nuclide identification instrument. Background Art

[0002] In recent years, with the development of science and technology, radionuclide identification instruments can help people quickly detect the type and intensity of radiation in the environment, and can be widely used in various fields such as nuclear power plant radiation monitoring, environmental monitoring, and atomic energy research.

[0003] At present, there are some portable nuclide identification devices on the market. The basic principle is: when high-energy photons or particles emitted by radioactive nuclides pass through semiconductor detectors, electron-hole pairs will be generated and uler radiation will be generated. At this time, if an electric field is applied to both ends of the semiconductor, the electron-hole pairs will quickly separate, the electrons will be attracted to the positive electrode, and the holes will be attracted to the negative electrode, generating a pulse current signal in the external circuit. The detector converts these signals into digital signals for analysis and processing to obtain the type and intensity of the nuclide. Semiconductor detectors generally use germanium or silicon materials and have high energy resolution and detection efficiency. It can accurately distinguish the gamma ray energy generated by nuclides. Because the characteristic gamma ray energy of nuclides is different, different nuclides can be distinguished. At the same time, the number of gamma rays detected can also calculate the intensity and activity of the nuclide.

[0004] The structure of the portable nuclide identification equipment is mainly composed of: shell, sodium iodide detector, peak-stabilizing K salt, LCD screen, PCB board, etc. The shell is used to fix the internal parts. The sodium iodide detector is the core component of the equipment as a probe. The detector is a peak-stabilizing K40. The K radiation in nature is very weak. There is a small amount of K40 in the peak-stabilizing K salt, which can enhance this radiation. In this way, the peak is stabilized quickly and the accuracy is high. The PCB board is the program control part of the entire instrument and the LCD screen displays the data measured by the instrument.

[0005] Usually, the peak-stabilizing K salt is in powder form and needs to be packaged in a container, and then the container containing the peak-stabilizing K salt is fixed on the side of the detector. However, the disadvantage of this is that the K salt cannot be evenly distributed around the detector, and when fixing the peak-stabilizing K salt container, it is limited by the space of the space instrument itself, and the operation is complicated and the assembly is inconvenient.
