Abstract:
A method for preventing radioactive contamination of porous surfaces comprising providing an apparatus for handling
radioactive material comprising a porous surface; exposing the porous surface to a vacuum; depositing a flowable precursor
material onto the porous surface, wherein the porous surface comprises pores and the vacuum is effective to substantially fill the
pores with the flowable precursor material; subjecting the flowable precursor material to energy sufficient to convert the
flowable precursor material to an effective sealant film comprising amorphous carbon. In a preferred embodiment, the porous
surface is an anodized aluminum surface.
