FGR-12 DCF values are used for submersion and ground shine. HotSpot incorporates Federal Guidance Reports 11, 12, and 13 (FGR-11, FGR-12, FGR-13) Dose Conversion Factors (DCFs) for inhalation, submersion, and ground shine. Additional programs deal specifically with the release of plutonium, uranium, and tritium to expedite an initial assessment of accidents involving nuclear weapons. These models estimate the downwind radiological impact following the release of radioactive material resulting from a continuous or puff release, explosive release, fuel fire, or an area contamination event. HotSpot includes four general models of atmospheric dispersion and depositions: Plume, Explosion, Fire, and Resuspension. The HotSpot atmospheric dispersion models are designed for near-surface releases, short-range (less than 10 km) dispersion, and short-term (less than 24 hours) release durations in unobstructed terrain and simple meteorological conditions. HotSpot provides a fast and usually conservative means for estimation of the radiation effects associated with atmospheric release of radioactive materials. Additionally, HotSpot provides emergency response personnel and emergency planners with a fast, field-portable set of software tools for evaluating incidents involving radioactive material. Current Central Registry Toolbox Version(s): V2.07.1Ĭode Owner/Developer: Lawrence Livermore National Laboratory (LLNL)ĭescription: The HotSpot Health Physics Code is used for safety-analysis of Department of Energy (DOE) facilities handling nuclear material.
