More Information
Summary:A cementitious surface contaminated with a radioactive substance is decontaminated by applying a micro-organism to the surface to degrade the surface. The residue which contains the radioactive substance is then removed by suction, scraping, brushing or abrasion blasting. The micro-organism might comprise an aerobic sulphur oxidising bacteria, or an anaerobic sulphate reducing bacteria, or a mixture thereof. Action of the micro-organism can be stopped as necessary by heating, or by depriving the micro-organism of nutrients.
