A model designed for baseline risk assessment based on measured concentrations in the environmental media.

RESRAD-Baseline is no longer being updated. It runs under Windows 95.

Follows EPA's guidance on risk assessment for superfund (RAGS).

Includes both radionuclides and hazardous chemicals.

Calculates radiological doses and cancer risks from exposure to radioactive materials and calculates hazard indexes and cancer risks from exposure to noncarcinogenic and carcinogenic chemicals, respectively.

Considers 14 exposure pathways: inhalation of dust, radon, and volatile chemicals, ingestion of plant, meat, milk, aquatic foods, soil, and drinking water, incidental ingestion of water while swimming, external exposure from soil and air immersion, and dermal absorption from swimming, showering, and soil contact.
