how much of an are can a nuclear bomb cover when its dropped??

Answer 1

depends upon the size and type

Answer 2

That really depends on the size and the type. However, this you can be certain, the effects of a nuclear bomb will effect the atmosphere and life for a long time after it's explosion.

Answer 3

It depends on the payload of course, but in termsof the largest nuke ever:

"The area of effectively complete destruction extended to 25 km, and ordinary houses would be subjected to severe damage out to 35 km."

"A 100 Mt weapon can level urban areas in a zone 60 km wide, cause heavy damage in a zone 100 km across, and cause 3rd degree burns in a region 170 km across (only a bit smaller than the width of West Germany). Such a weapon can only be used as a means of destroying an entire urban region - a major urban complex including suburbs and even neighboring cities."

That describes the Tsar Bomba, the largest nuke ever made by mankind in the former USSR.

Answer 5

At 08:15, the Enola Gay dropped the nuclear bomb called "Little Boy" over the center of Hiroshima. It exploded about 600 meters (2,000 feet) above the city with a blast equivalent to 13 kilotons of TNT, instantly killing an estimated 70,000–80,000 people. Of this number, there were approximately 2,000 Japanese Americans who died from the blast and another 800-1,000 who lived on as hibakusha. As U.S. citizens, many of these Japanese Americans were attending school before the war and had been unable to leave Japan. At least 11 U.S. POWs also died. The radius of total destruction was about 1.6 km (1 mile), with resulting fires across 11.4 square km (4.4 square miles). Infrastructure damage was estimated at 90% of Hiroshima's buildings being either damaged or completely destroyed.

At 11:02, a last minute break in the clouds over Nagasaki allowed Bock's Car's bombardier, Captain Kermit Beahan, to visually sight the target as ordered. The "Fat Man" weapon, containing a core of ~6.4 kg (14.1 lb) of plutonium-239, was dropped over the city's industrial valley. It exploded 469 meters (1,540 feet) above the ground exactly halfway between the Mitsubishi Steel and Arms Works in the south and the Mitsubishi-Urakami Ordnance Works (Torpedo Works) in the north. This was nearly 3 kilometers (2 mi) northwest of the planned hypocenter; the blast was confined to the Urakami Valley and a major portion of the city was protected by the intervening hills.

According to most estimates, about 70,000 of Nagasaki's 240,000 residents were killed instantly, and up to 60,000 were injured. The radius of total destruction was about 1.6 km (1 mile), followed by fires across the northern portion of the city to 3.2 km (2 miles) south of the bomb. The total number of residents killed is believed to be as many as 80,000, including those who died from radiation poisoning in the following months.

Answer 6

There is the main blast and the after effects that covers much more area depending on stuff like the wind.

Answer 7

In the neighborhood of about 12 square feet. They are physically
fairly small. You don't have to drop it to find out how much area
it has.

Answer 8

depends on what type, putounium, urunauim, and my favorite (and most powerful) hydrogen. its enough to annialite an entire city so its not a big area. if you look at the earth as a whole, a city is tiny.

Answer 9

depends on the type, size, and if burst in the air or on the ground

Answer 10

Depends on what kind and how big.A BIG hole though,even with a small one.
