Abstract

Huge amounts of Low Level Radioactive Waste and Low Level Radioactive Mixed Waste, approximately 258,000 m3, are being generated at Rocky Flats Environmental Technology Site. Most of this waste is not radioactive throughout its volume. Instead it is contaminated on its surface, and is likely to qualify for shipment under the U.S. Department of Transportation (DOT) classification of Surface Contaminated Object (SCO). Use of the SCO classification has produced time and cost benefits along with increased radiological worker safety. SCO Waste is characterized using decentralized, simple field methods with two goals: 1) demonstrating compliance with the DOT shipping class and 2) calculating the waste container activity and concentration. The specific methods, instruments and statistical processes used to characterize SCO low level waste are described.
