The HotSpot Heath Physics Code V2.07.1 User's Guide is available on the HotSpot web site.While Wi-Fi tethering on your smartphone is a quick and easy way to set up a mobile hotspot, some people may prefer a dedicated mobile hotspot device. Additionally, your organization may require acceptance for use activities to be performed prior to the use of Hotspot. These processes and requirements may prohibit direct download by others than those authorized to install software on the intended computer. ![]() Downloading of Hotspot must follow your organization’s software acquisition and procurement processes and requirements. To download the Hotspot software, registration is required each time the Hotspot software is downloaded. These reports are provided on this web site as a courtesy to the DOE community. Note: Non-DOE issued reports and publications are not endorsed for technical content by DOE. Specific information and LLNL documentation for Hotspot are available on the NARAC Hotspot site. The National Atmospheric Release Advisory Center (NARAC) at LLNL maintains HotSpot. Reports and publications related to Hotspot: Default percentile values are 50th, 90th, 95th, 99th, and 99.5th, and can be changed by the user. HotSpot V 2.07.1 now includes a module that can be used to calculate the 95th percentile of the dose distribution for up to 20 radial centerline distances in each of 16 wind direction sectors (direction dependent), and all 16 sectors (direction independent) using historical meteorological data input by the user. In June 2010, DOE approved HotSpot V2.07.1 for inclusion in the Central Registry. The results of the evaluation were documented in a report with recommendations which were implemented by LLNL. In March 2007, DOE completed an evaluation of Hotspot V2.07.1 against DOE's safety software quality assurance criteria. ![]() This acute mode can be 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. 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.
