The Department of Homeland Security Science and Technology Directorates Chemical Security Analysis Center is developing a modeling tool that estimates the hazard and related human health consequences from thousands of plausible threat scenarios.

After validation and further development, it will be integrated into national- and regional-level risk analysis.
