Experimental simulation of radioactive decontamination with Excimer laser

摘要

Laser ablation is a powerful tool to clean the radioactively contaminated surface in nuclear industry. A prototype was set up to test the decontamination of the radioactively contaminated surface using simulated sample. A laser induced breakdown spectroscopy was used to monitor the progress of the contaminated surface layer removal. More than 80% of the contamination was removed after 100 shots KrF laser irradiation with the intensity of 1 J/cm2.
