[ RadSafe ] Modeling Atmospheric Transport and Dispersion

Would Hotspot 2.07 be of use? It is available from Lawrence Livermore Lab. It's strictly Gaussian. I don't know if LLNL makes public, free software which incorporates Lagrangian modeling. I believe EPA publishes a package called CAP 88 which might be available.

If a Fukushima type event occurred in the US, universally adopted modeling originates from the NARAC through a group known as IMAAC (Interagency modeling and  atmospheric assessment center). If you Google NARAC, you should get a lot of useful information. IMAAC would be (or is supposed to be) the single modeling "voice" used by interagency response forces to a radiological event.

Subject: [ RadSafe ] Modeling Atmospheric Transport and Dispersion

Are there publicly accessible tools for modeling atmospheric transport and dispersion similar to US Department of Defense's "HPAC" – Hazard Prediction Assessment Capability?

Disregarding the intended message of the report, "HPAC" was used to create this report "What if the Fukushima nuclear fallout crisis had happened here (US)?" link http://www.nrdc.org/nuclear/fallout/
