3. DESCRIPTION OF PROGRAM OR FUNCTION

SMART calculates early offsite  consequences from nuclear reactor accidents. Once the air and ground concentrations of the radionuclide are estimated, the early dose to  an individual is calculated via three pathways: cloudshine, short-term groundshine, and inhalation.

4. METHOD OF SOLUTION

The model predicts time-integrated air concentration of each radionuclide at any location from release as a function of time-integrated source strength using the Gaussian profile or, optionally, as an average over the cross-section based on a top-hat distribution.
The solution procedure uses simplified meteorology and involves direct analytic integration of air concentration equations over time and position. Dispersion parameters are calculated from exponential  fits to the Pasquill-Gifford curves for six atmospheric stability classes designated A to F.
