Muon imaging method and vehicle-mounted radioactive material monitoring system

Abstract

The invention provides a muon imaging method and a vehicle-mounted radioactive material monitoring system. The muon imaging method is characterized in that it includes the following steps: S1, using a track reconstruction algorithm to reconstruct the muon angle measurement data to obtain an initial reconstructed image f 0 ; S2, with the initial reconstructed image f 0 As the initial value, the algebraic reconstruction algorithm is used to iterate to obtain the reconstructed image f ART ;S3, for f ART Minimize the total variation several times to get the image f ART‑TV ; S4, repeating S2 to S3 until a reconstructed image f that meets the preset quality is obtained t ; and S5, use the algebraic reconstruction algorithm to f t Iterate to get the final reconstructed image f final . According to the invention, real-time radioactivity monitoring can be realized, and it is especially suitable for monitoring the state change of radioactive waste during transportation, thereby reducing potential risks during the transportation of radioactive waste.

Description

technical field [0001] The invention relates to the field of nuclear safety detection, in particular to a muon imaging method and a vehicle-mounted radioactive material monitoring system. Background technique [0002] In recent years, with the vigorous development of the nuclear power industry, a large amount of radioactive waste needs to be disposed of. In order to solve the problem of radioactive waste disposal, my country promulgated the "Guidelines for the Research and Development Planning of Radioactive Waste Geological Disposal" in February 2006, which first proposed the plan to build a radioactive waste geological disposal warehouse in the middle of this century, and initially selected it in July 2011. The preferred pre-selection area for the radioactive waste repository located in Northwest Gansu. [0003] However, almost all the nuclear power plants currently in service and planned to be built in my country are distributed along the southeast coast, and are far away...

AI Technical Summary

Problems solved by technology

[0003] However, almost all the nuclear power plants currently in service and planned to be built in my country are distributed along the southeast coast, and are far away from the northwest inland repository. The terrain and climate changes are complicated during transportation, and the transportation vehicles will inevitably produce bumps and vibrations. Therefore, It is very important to ensure the safety of radioactive materials
