<p>A system and method for cleaning components contaminated with radioactive materials uses dry ice blasting to remove the radioactive contaminant from the contaminated component in a chamber including a directed air flow. The removed contaminant is transported by the directed air flow for collection in a filter, which may be configured as a HEPA filter. During the cleaning process, the dry ice used for the blasting process sublimates into gaseous carbon dioxide such that no incremental contaminated cleaning media or residue is generated during decontamination of the component. Because the dry ice is non-corrosive, non-abrasive and environmentally neutral, damage to the component being cleaned and decontaminated is prevented or substantially avoided. Because dry ice sublimates on impact, cleaning of electrical components without compromising electrical function is enabled.</p> |
