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.

Systems Approach for Wide-Area Remediation
	Initial development of remediation strategies for a wide-area
radiological incident will start immediately following the
contamination event
	Identification of the materials found in both the indoor and
outdoor portions of the affected areas developing approaches for optimal cleanup of those surfaces and
materials
	Decontamination and waste management processes are linked
	Prioritize remediation processes as soon as possible

This tool will aid responders and decision makers to implement an integrated
response by effective analysis of many competing considerations, with a goal
of a rapid, effective remediation that minimizes economic and health impacts
to the affected community.
