Human Health Risk Assessment

SADA provides a full human health risk assessment module and associated databases. The risk models follow the EPA's Risk Assessment Guidance for Superfund (RAGS) and can be customized to fit site specific exposure conditions. The following landuse scenarios and exposure pathways are available for both radionuclides and nonradionuclides to calculate risk and data screening levels.

Landuse Scenarios

• Residential
• Industrial
• Agricultural
• Recreational
• Excavation

Exposure Pathways

• Ingestion
• Inhalation
• Dermal contact
• External (radionuclides)
• Food consumption
• Combined Exposure

Risk results can be produced in standard tabular format or graphically.
