How big is a "suitcase nuke"?
610389
It's about the size of a suitcase!\nThey call it a suitcase nuke because it fits in a suitcase and it's about .300 kilotons, much much lighter and less powerful.

It was low-enriched uranium, not weapons grade. So the answer is NONE. No nukes with THAT uranium. It would have to be enriched , and would amount to a miniscule amount after that.\n\n"could potentially be used in a radiological dispersal device," or dirty bomb.

As big as a hazelnut.

The bombs used in Hiroshima and Nagasaki were fission bombs, with respective yields of 15 and 22 kilotons.  A fission bomb generates about 4,000,000 Megajoules of energy per kiloton of explosive force, so the Hiroshima bomb would have produced 60,000,000 Megajoules of energy while the Nagasaki bomb produced 88,000,000 Megajoules.

They range in power. About 100 megaton of TNT. The radiation from the bomb also kills.

Whoa, man, why do you want to know? Do you know how suspicious you look after 9/11? \n\nthe critical mass for U-235 is 15 kilograms.

It would do nothing.  In 1994, a comet (Shoemaker-Levy) crashed into Jupiter.  I don't have the exact numbers on the equivalent to a nuclear bomb, but it was much more powerful than any bomb.  Jupiter kind of sat there and shrugged it off without much effect.\n\nEdit:  Found a site that says *one* fragment of the comet was the same as 225,000 megatons.  The biggest fragment was the same as 6 million megatons.\n\nhttp://www.isc.tamu.edu/~astro/sl9/cometfaq2.html

7 satelites at least.\nFiring nuke? not necessary..the nukes are carried by vehicle.... totaly undetectable....and so much more cheaper...

The bomb type has nothing to do with the airplane type.  Granted that Mirage 2000's can carry only up to certain amount of weight, thus limiting the bomb size, but please specify the type of bomb you're going to hypothetically throw at that bridge.\n\nI.e. specify bomb explosive, weight etc

Khrushchev warned in a filmed speech to the Communist parliament of the existence of a 100 Mt bomb. \nThe Bomb called the Tsar was dropped from a TU 95 at a height of 10.500 metres using a parachute drop.The fireball touched the ground, reached nearly as high as the altitude of the release plane10,500 metres, and was seen 1,000 km away. The heat could have caused third degree burns at a distance of 100 km. The subsequent mushroom cloud was about 60 km high and 30–40 km wide. The explosion could be seen and felt in Finland, even breaking windows there.[citation needed] Atmospheric focusing caused blast damage up to 1,000 km away. The seismic shock created by the detonation was measurable even on its third passage around the earth.

It depends on four things:\n\n1. Size of the bomb's yield (measured in megatons)\n2. The type of bomb (atomic, hydrogen, etc.)\n3. The terrain around where the bomb detonates (mountains or desert, etc.)\n4. The elevation of the bomb at detonation (some of them are set to explode ABOVE the terrain).\n\nBut, to give you a typical example:\nCommon single MIRV warhead (thermonuclear type bomb that is 10 Megatons, which is equivalent to 10 thousand tons of TNT), exploding 2000 feet over a desert with low rolling hills would have these ranges, in the order in which an instrument would first measure it:\n\n1. XRAY and Gamma Ray effect: 1000 mile diameter. Causes almost all electrical appliances to stop.\n2. Heat from the light: 50 mile diameter\n3. Permanent blindness from the light: 20 miles\n4. 3rd degree skin burns: 18 miles. 2nd degree: 16 miles. 1st degree: 15 miles.\n5. Killed/Bents/Destroyed biological material (animals, Humans and foliage): 12 miles.\n6. Vaporized biological material (animals, Humans and foliage): 10 miles\n7. Vaporized concrete up to 4 feet thick: 5.5 miles.\n8. Physical crater in the Earth, caused by all this: 1 mile in diameter and about 100 feet deep.\n\nThen AFTER the blast: \n- Nuclear radiation "Hot Zone" death in 24-48 hours would be about 25 miles.\n- Nuclear radiation "Hot Zone" sick or die in 30 days would be about 100 miles.\n- Also: Nuclear fallout - up to thousands of miles downwind.\n- Uninhabitable for about 250 years within 50 miles.\n\nHope this helps.\n\nIf this is the best answer, please vote it the best answer. Thanks!

Check this article: http://www.debka.com/article.php?aid=1158\n\n"Tehran is planning a massive hole-in-the-corner program, using 155,000 centrifuges to produce 3-5 nuclear bombs a year by the end of 2007..."

Nuclear weapons have been made anywhere from a few kilotons in yield to 20 Megatons and up.\n\nIt's damage will depend upon where it is detonated or how high it is detonated above the ground.  If one is detonated at ground level the damage will not spread as far as one that was detonated above ground level.\n\nCheck out the Federation of American Scientests Website.

I recollect seeing 200,000 to 250,000 for both cities, including the aftermath.  The Hiroshima bomb was a low yield 15 kiloton device.  The strategic devices today are around 400-500, while the tactical nukes range from .3 to 200.  Some world we live in.

Thats about 2 large suitcases full of coke baby! I'm sure I could carry it by myself, but let me know if you need some help!

Here is some info on them however it's more of an informative piece..  not about any recent news stories.\n\nhttp://www.users.bigpond.com/sch57/portnoarlunga/beachworms/beachworms.html\n\nScary to think it can be 8 feet long!
