For those of you interested in nuclear weapon effects I ran across an online blast calculator for overpressure effects with live maps. http://meyerweb.com/eric/tools/gmap/hydesim.html?inpyield=1000

According to the webpage the “HYDESim maps overpressure radii generated by a ground-level detonation; these radii are an indicator of structural damage to buildings. No other effects, such as thermal damage or fallout levels, are included in this tool. Note that the displayed rings are ‘idealized’; that is, no account is taken of terrain, urban density, ground type, weather conditions, and so on.”

There is also a mapplet that shows the thermal damage caused by a nuclear explosion
http://www.carloslabs.com/projects/200712B/GroundZero.html

Has anybody seen a fallout level calculator similar to these or possibly even a calculator that incorporates these three aspects of blasts?

Anyway the above links do give some interesting results and are worth a look.

HPAC from DTRA will do all that and some more. Not sure how a civilian can obtain a copy but might not hurt to send an email to them and ask. Works on most PCs, fairly easy to work.

Other than that, no, haven't seen a fallout contour plot.

Thanks for the tip, below is the link for general information on requesting software and applying for access to the password protected ACECenter at the Defense Threat Reduction Agency (DTRA) according to the webpage the Hazard Prediction and Assessment Capability (HPAC) software is available.

http://www.dtra.mil/rd/programs/acec/upgrade.cfm

Just have to decide if it is worth trying to register since I have no reason other than curiosity my guess is that I won’t be approved for download. Either way thanks again.

Say your the local chapter on radiation preparedness group for your town that resides near a nuclear reactor. Technically, anything made/written by the government is suppose to be public domain.

I would love to understand how terrain affects the blast effects and what a person could do to maybe engineer landscape that would increase survivability of a home structure.
"The Effects of Nuclear Weapons" by Glastone/Dolan, can download here:http://www.survivalistboards.com/downloads.php?do=file&id=1390

It has a survivability section for blast, loading of different types of buildings and such. Its allot of empirical test data fitted to some tables but its not too bad in finding what stress loads and overpressure limits some buildings can take. Also takes into account the angle and shape of the building.

Nuclear Weapons Calculator

If have Microsoft Excel (or Works) or a good calculator with exponential
powers

Gives lethal radius (in meters) for thermal, blast, radiation effects

Y = Yield (in tons) / 2500

Blast = Y^.41 (4.7 psi - collapse most structures)

Thermal = Y ^.33 (3rd degree burn on exposed flesh)

Radiation = Y^.19 (500 rem)

Example

1KT (1000 tons)

Blast 687 meters

Thermal 739 meters

Radiation 840 meters

Those formulas look familiar! You get those from 'The Effects of Nuclear Weapons' by Glastone and Dolan?

Interesting subject I have seen this webpage http://www.carloslabs.com/projects/2...roundZero.html before but not the other ones. Thanks everyone.

These simulations are one of the things I have been meaning to use to help pick my BOL. I know there are some other posts concerning BOL selection maybe would should compile all the tools and suggestions in one place. I gues I'll work on it when I get a chance but any suggestions would help.

That is a great idea. Just to get us started, I know you can get an idea about the categories of plant life capable of growing at your BOL with USDA Plant Hardiness Zone maps. http://www.usna.usda.gov/Hardzone/ushzmap.html

I used some of the maps you provided, but I'm not sure it's clear on the damage and miles outside of the blast. I'm trying to decide the safest distance from Washington, or really the surrounding cities like Baltimore and Philly.

in an exchange with a real foreign power, there is a good chance that whole are would saturated with a walking carpet effect.

in a single blast by a terrorist or such with a small primative bomb, i'd guess that @ 20 miles, the effect would be diminished enough that you'd probably okay after a mild case of radiation sickness if you were outside. Nukes aren't as damaging as most people think (i've heard people say that one bomb dropped on Sandusky Ohio, would take out cleveland and toledo with one swoop, and that's just not true.)

Using a few calculators, I "decided" that 12 miles minimum would be acceptable to me. This accounts for blast for most of the expected stuff.

I say "minimum" because some of these buggers will miss. I want some padding for that. When I move, my padding will hopefully be somewhere in the neighborhood of 100 miles, and the errant device will be somewhere in Pelosi's front yard.
