CO2 laser assisted removal of UO2 and ThO2 particulates from metal surface

► Pulsed laser irradiation can remove radioactive particulates from metal surface. ► Adhesion of ThO2 particulates are more than UO2 particulates. ► Threshold fluence to remove UO2 particulates is less in comparison to ThO2 particulates. ► Cleaning efficiency can be increased by choosing wave length, which is absorbing to particulates.
