Radiological Safety Analysis Computer (RSAC) Program

Overview

RSAC is a radiological dose assessment tool that calculates the radiation dose an individual may receive following a release of radionuclides to the atmosphere. Users can generate a fission product inventory from reactor operating history or nuclear criticality events, or they can import an existing inventory directly into the software.

Capabilities

RSAC models radionuclide decay, daughter ingrowth, filtration systems, environmental transport, and changing weather conditions throughout an event. It supports both instantaneous and ongoing releases from seconds to days and can model point or area sources. Dose calculations include inhalation, immersion, ground deposition, ingestion, and resuspension pathways.

RSAC 7 includes multiple atmospheric dispersion models including Pasquill Gifford, Hilsmeier Gifford, and Markee models and uniquely models Class F fumigation conditions. Users may also input plume dispersion parameters directly. Internal dose calculations follow ICRP 26 and 30 and ICRP 60, 68, and 72 methodologies, and RSAC 7 can compute both lifetime dose and 24 hour acute dose for sabotage scenarios.
