Frequent Questions

Is CAP-88 PC appropriate for estimating exposures from short-term or "accidental" releases?

CAP-88 is not an appropriate program for modeling short term or “accidental” releases for a few reasons. The software uses dose/risk conversion factors that rely on chronic, low-level exposure predictions and utilizes the Gaussian model, which is a long-term model that estimates average dispersals of radionuclides. Additionally, the software relies on weather data that utilizes annual averages, so a short-term release would not work.
