technical BRIEF oEPA a www.epa.gov/nhsrc WASTE ESTIMATION SUPPORT TOOL (WEST) Management of waste from a Radiological Dispersal Device (RDD) incident would likely constitute a significant fraction of the total remediation cost and effort. The U.S. EPA's RDD Waste Estimation Support Tool (WEST) is a planning tool for estimating the potential volume and radioactivity levels of waste generated by a radiological incident and subsequent decontamination efforts. WEST supports decision makers by generating a first-order estimate of the quantity and characteristics of waste resulting from a radiological incident, and allows the user to evaluate various decontamination/demolition strategies to examine the impact of those strategies on waste generation. — .
