The invention discloses a nuclide energy spectrum peak searching method based on multi-structure element morphology. The method comprises the steps: collecting nuclide detection data as original nuclide energy spectrum data; carrying out effective information screening, smoothing and other preprocessing on the original nuclide energy spectrum data; selecting four structural flat structural elements with the same size and different directions to carry out morphological change processing of corrosion expansion on the preprocessed energy spectrum data; calculating the difference between the energy spectrum data after morphological change processing and the energy spectrum data after preprocessing, and achieving the peak searching of nuclide finally after difference energy spectrum, peak stripping and false peak elimination, so the accuracy is higher. By selecting the flat structure elements with the included angles of 0 degree, 45 degrees, 90 degrees and 135 degrees with the horizontal direction, different directions of the curve can be controlled more carefully, the energy spectrum peak positioning accuracy of the method is higher, the peak information is not easy to lose, and the peak information can be better identified so as to determine the peak position.
Description
technical field [0001] The invention relates to the fields of nuclide identification and energy spectrum analysis, in particular to a nuclide energy spectrum peak-finding method based on multi-structural element morphology. Background technique [0002] With the vigorous development of nuclear energy in nuclear power, nuclear weapons, medicine, industry and agriculture, etc., tens of thousands of cubic meters of low- and intermediate-level radioactive waste have accumulated. While enjoying the convenience brought by nuclear energy technology, they have to face a very difficult problem - the disposal of nuclear waste. In order to enable the smooth development of nuclear waste disposal, the identification of nuclear elements in nuclear waste barrels in the early stage is very important. In the process of radionuclide energy spectrum measurement and nuclear data analysis, the interference caused by statistical fluctuations and environmental noise on the qualitative law analysi...
