Nuclear Bunker Busters

This will link you to an animation sequence (http://www.ucsusa.org/global_security/nuclear_weapons/nuclear-bunker-buster-rnep-animation.html) by the Union of Concerned Scientists about nuclear bunker busters.

(interestingly, they use strikes against Iran as an example)

have heard of these bombs before,i think they wanted to use them to wash out osama bin laden,maybe now scotland should check to see what is being carried on board aircraft im not saying bush is supplying them but with iran now refusing a un resolution who knows ,question is why is bush so quiet on these issues lately and is bush and blair going to make the same mistakes as they did with iraq.final note we are now seeing demonstrations in the other parts of the middle east and again burning US flags and Israeli flags its only going to going to fuel hate against the west how desperate is bush to save face and keep the US popular with the rest of the world

Interesting. I'll work out a fallout plot over the next few days for comparison to see how accurate they are.

Here it is finally.

For the life of me I could not find real time meteorological data for Iran. I finally did. This is real time data from about 3 weeks ago.

It explains why nothing has happened, and why nothing will happen for a few more months.

It was monsoon season. The winds were blowing west to south. Now they are changing and blowing mostly west to north. As summer comes along, the winds will be blowing from the Arabian Sea in the south to the north and east.

Using nuclear weapons now, or using conventional weapons were nuclear materials might be present risks contaminating US naval vessels in the Persian Gulf, troops in Iraq and the Kuwaitis and Saudis (plus the Bahrain, the UAE, Qatar and Oman).

A brief explanation.

The white lines represent vector plots for wind speed, direction, wind layer and fall time. Each red square is a 5,000 ft interval, up to 60,000 feet.

The grid that I superimposed is about 1 km. Basically, a nominal sized particle, which is 143 microns, will fall through the wind layers over time. The very last red square would be how long it takes something at 60,000 feet to fall to the ground.

When predicting fallout from fission-fusion weapons, only the fission part counts. Fusion produces Helium, and I'm sure you're all aware that Helium is not radioactive.

In this instance, a 400 kt warhead has a fission-fusion ratio of 12/380. In other words, it takes about 12 kt to fuse enough deutrium to get a yield approaching 400 kt.

For a 1.2 mt warhead, the ratio is 20/ 1100 more or less.

The yellow lines are the boundaries of the immediate fallout zone. The blue semi-circles are 1, 2 and 3 after detonation.

Anyone in the first zone would be seriously contaminated and probably die without medical assistance. In Zone 2, you could stay up to 4 hours without being seriously injured. Zone 3 you can stay about 24 hours safely without much risk. Zone 3 would be about 40 km south of the city.

That's the bulk of the fallout, about 75% right there in those 3 zones. The cloud top won't be higher than 60,000 feet and it will take just over 3 hours for the cloud to "fall." It will have a diameter of about 14-15 miles, so figure it will blot out the sun and make it dark.

I put Esfahan as ground zero, even though the facility in question is outside the city, but I don't know in which direction. Civilians wouldn't be affected by the blast or heat, but casualties could be anywhere from 30,000 to 1.5 Million, depending on whether or not the fallout blows over the city.

Very interesting dude !! Nice work !!
