Multi-mode quick nuclide detection system

Abstract

The invention discloses a multi-mode quick nuclide detection system, which comprises a detector module, used for acquiring a nuclear pulse signal output under the excitation of a radionuclide; a signal acquisition module, used for converting an acquired signal into a discrete digital signal and eliminating a base-line shift; a digital processing module, used for filtering the acquired signal and eliminating base-line shift data; an amplitude value extracting module, used for extracting an amplitude value of a trapezoid pulse and correcting the amplitude value; a data storage module, used for storing data; a data transmission module, used for transmitting data to an upper computer or transmitting a command of the upper computer into a central control module; and the central control module,used for storing the command and processing the data. The existing shortcomings are overcome; and technical effects of reasonable design and accurate detection of the detection system are achieved.

Description

technical field [0001] The invention relates to the field of radionuclide detection, in particular to a multi-mode rapid nuclide detection system. Background technique [0002] At present, radionuclides are widely used in many fields such as nuclear power plants, medical testing, and biological sciences. While providing convenience, it also inevitably brings nuclear radiation pollution. Nuclear radiation pollution will not only cause irreversible pollution to the environment, but also cause great harm to human beings. Especially after the Fukushima nuclear radiation crisis in Japan in 2011, countries have strengthened nuclear safety monitoring. With the emergence of large-scale integrated circuits, nuclide detection devices are also developing towards portability and miniaturization. At the same time, higher requirements are put forward for the rapidity and accuracy of nuclide detection. [0003] At present, the processing of nuclear signals generally adopts digital filte...
