Laser Decontamination Research on Radioactive Simulated Specimens in Air

The study on the laser decontamination parameters was carried on with the simulated radioactive specimens made by LLRW and using APEX laser. The efficiency of different laser parameters such as laser intensity, laser frequency, laser angle and laser scanning speed were investigated on the decontamination factor(DF), and then the optimized laser decontamination parameters were obtained. Using the optimized parameters, the laser decontamination was studied with the simulated stainless steel specimens by the laser decontamination equipment. The experimental results show that the DF is more than 200, and the peeling thickness on the stainless steel base is less than 20 μm.
