What else can I help you with?
What type of nuclear detonation occurs below 100000 ft?
airburst
Why was airburst chosen instead of surface burst for World War 2 nuclear bombs?
Greater damage from blast and thermal radiation.
When did the meteor fall into Siberia?
The Tunguska event happened on June 30, 1908. It was an airburst event; no crater. (A wonderful discovery sequence followed)
What was the nuclear bomb in Nagasaki?
A MK-3 Plutonium Implosion Fission Bomb, yield ~21KTons, airburst @ ~1,800 feet. See link for more info.
What element was the first to make the atomic bomb?
July 16, 1945 Gadget, Trinity Test tower shot, NM - PlutoniumAugust 6, 1945 Little Boy, Combat airburst, Hiroshima - UraniumAugust 9, 1945 Fatman, Combat airburst, Nagasaki - PlutoniumJuly 1, 1946 Able, Crossroads Effects Test airburst, Bikini atoll - PlutoniumJuly 25, 1946 Baker, Crossroads Effects Test shallow underwater, Bikini atoll - PlutoniumCanceled 1946 Charlie, Crossroads Effects Test deep underwater, Bikini atoll - Plutoniumetc.Take your pick, either the first atomic explosion (Plutonium) or the first combat use (Uranium).
Which type of nuclear burst occurs above 1000 feet?
A nuclear burst that occurs at an altitude above 1,000 feet is classified as an "airburst." In an airburst, the detonation happens in the atmosphere rather than at ground level, maximizing the blast's radius and thermal effects while minimizing fallout. This type of explosion is often used to achieve greater destruction over a wider area and to reduce the amount of radioactive debris that falls to the ground.
When did US have atomic bomb with delivery system?
1945, the delivery system was composed of a B-29 bomber with Silverplate modifications and gravity bomb casings with RADAR altimeter airburst fuses.
How much radiation does a nuclear bomb produce?
That will vary dramatically with the design of the bomb and whether it is an airburst or a surface burst.
How far does the blast from a nuclear weapon travel?
There are too many factors to give you one simple answer. It will depend on the yield (size) of the weapon, where it is detonated (on ground, low airburst, high airburst) etc. A 150 kiloton weapon, low airburst, would cause 3rd degree burns at about 5.4 kilometers, and cause total destruction of ordinary buildings (from blast) out to 4 kilometers. Current day nuclear weapon are LESS powerful than the VERY large weapons from the 50s and 60s- better guidance systems can place the weapon on target within a matter of feet- in the 1960s, it was a matter of miles.
How long did it take the atomic bomb to hit the ground?
If you are asking specifically about the two bombs dropped on Japan in WW2, they were fuzed for airburst, so they did not hit the ground. Both exploded between 1500 ft & 2000 ft altitude. Airburst was selected to maximize blast & thermal flash damage effects area.
Do nuclear bombs explode before they hit the ground?
It will if it is fused for airburst. This is selected to maximize the area and severity of blast and thermal flash effects.
How big is a nuclear blast radius?
Little Boy was the nuclear bomb detonated over Hiroshima. It used uranium and had an explosive blast equivalent to 12,500 tons of TNT. A 1 megaton hydrogen bomb, hypothetically detonated on the earth's surface, has about 80 times the blast power of that 1945 explosion. Considering the tonnage of a bomb to be contant, The blast radius varies dependent on whether it is a ground burst or an airburst. Further, the height of the airburst above ground affects the radius too. At a height of 1900 feet above ground, Little Boy produced a blast radius of 1 mile; an area of some 4.7 square miles.
