In the event of terrorist activity involving the explosive dispersion of radioactive materials (a 'dirty' bomb), a number of different types of surfaces and substrates, including concrete, granite, brick, cinder block, tile, asphalt, wood, glass, plastic, iron, and steel, may become radiologically contaminated. Incident cleanup is assumed to involve decontamination of these surfaces. Laboratory testing was conducted using samples of concrete, ferrous metal, steel, aluminum, lead, tin, glass, lexan, vinyl, asphalt shingle, wood, and rubber surfaces. The surfaces were sprayed with Cs-137 or Co-60 solutions to simulate contamination. The entire surface area of the samples was surveyed using a Ludlum Model 2360 scaler/ratemeter with Ludlum Model 43-93-2 100 cm{sup 2} open area alpha/beta scintillation probe. The surfaces were then decontaminated using RadPro{sup R} chemical decontamination technology that is currently field proven and ready to deploy. The entire surface area of the samples was re-surveyed following decontamination. The RadPro{sup R} chemical decontamination technology was able to remove virtually all of the removable contamination and over 90% of the fixed contamination from these surfaces during the laboratory testing.
