![]() ![]() Additional tools deal specifically with the release of plutonium, uranium, and tritium to expedite an initial assessment of accidents involving nuclear weapons. HotSpot Software Toolsįour general software programs-Plume, Explosion, Fire, and Resuspension-estimate downwind radiological effects following the release of radioactive material resulting from a continuous or puff release, explosive release, fuel fire, or an area contamination event. This acute mode is used for estimating the immediate radiological impact associated with high-acute radiation doses (applicable target organs are the lung, small intestine wall, and red bone marrow). In addition to the inhalation 50-year Committed Effective Dose Equivalent DCFs, acute (1, 4, 30 days) DCFs are available for estimating deterministic effects. FGR-12 DCF values are used for submersion and ground shine. The HotSpot Radionuclide Library incorporates Federal Guidance Reports 11, 12, and 13 (FGR-11, FGR-12, FGR-13) Dose Conversion Factors (DCFs) for inhalation, submersion, and ground shine. You do not need to have a NARAC or CMweb account to access HotSpot. To register and download the HotSpot software, click here. The HotSpot codes have been developed for the Windows operating system(s). These models provide a fast and usually conservative means for estimation of the radiation effects associated with the atmospheric release of radioactive materials. 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. ![]() The software is also used for safety analyses of facilities handling nuclear material. The HotSpot Health Physics codes were created to provide emergency response personnel and emergency planners with a fast, field-portable set of software tools for evaluating incidents involving radioactive material. ![]()
