What is the blast radius of a 340KT yield surface burst?
EcclesJordanTrigger
The blast radius of a nuclear surface burst will vary depending on the building density, meteorological conditions (air pressure, temperature, humidity), terrain. Also, since no specific level of damage or overpressure ring was specified, here are some examples of what to expect:
For a 340 kt surface burst:
We can expect damage up to 12 miles from the hypocenter (broken windows, etc., but capable of causing injuries).
Expect moderate damage to houses and light damage to all structures up to about 5 miles from the hypocenter.
Houses would be destroyed and moderate to severe damage to even reinforced concrete structures at the 5 PSI overpressure ring about 2 miles from the hypocenter.
About 1.6 miles from the hypocenter (7 PSI ring) most large reinforced structures like skyscrapers and the like would be severely damaged or destroyed.
About 1 mile from the hypocenter, pretty much all structures would be destroyed (15 PSI).

The blast radius of a 340 kiloton yield surface burst can vary depending on factors like local terrain and weather conditions. As a general guideline, for a 340 kiloton blast, the immediate severe blast effects can extend up to around 3.2 miles, with damage from the pressure wave extending to approximately 13 miles.

What is the blast radius of a nuke?
The blast radius of a nuclear bomb can vary widely depending on factors such as the size of the bomb and the height at which it detonates. For a typical nuclear bomb, the blast radius can range from a few hundred meters to several kilometers. The effects of a nuclear explosion are not only limited to the immediate blast radius but also include secondary effects like thermal radiation and radioactive fallout.
Destructive radius of a five kiloton nuclear explosion?
The destructive radius of a five-kiloton nuclear explosion is typically around 500 to 700 meters, resulting in significant destruction of buildings and infrastructure in the immediate vicinity of the blast. This radius can vary depending on factors such as the height of the explosion, terrain, and weather conditions. However, it's important to note that the effects of a nuclear explosion extend far beyond the immediate blast radius due to factors like heat, radiation, and fallout.
What type of atomic burst is deadlier air burst surface burst or subsurface burst?
An air burst is typically the deadliest type of atomic burst as it creates a large area of devastation due to the shockwave, heat, and radiation released. A surface burst can also be very deadly as it creates more fallout, causing widespread contamination. A subsurface burst is usually less deadly as the ground can help contain some of the initial blast and reduce the immediate impact.
What words mean the same thing as explosion?
Blast, burst, detonation, or eruption.
Which type of nuclear burst occurs under 10000 feet but the fireball dosent contact the earth's surface?
An air burst occurs when a nuclear explosion happens in the air rather than on the ground. In this scenario, the fireball does not touch the Earth's surface, making it an aerial detonation. This type of burst can cause widespread damage through the blast wave, heat, and radiation effects.
How many miles were the atomic bomb on japan?
Cannot answer; depends on the yield, burst height/depth, etc. Some examples of optimal altitude airbursts:Low yield tactical weapon, blast radius < 0.1 mile.Tzar Bomba (over 50MTon yield), blast radius 60 miles.Above or below the optimal altitude the blast radius of an airburst is reduced.Surface and subsurface bursts have much smaller blast radius values than airbursts. A deep enough subsurface burst can be entirely contained and have no effect on the surface (except for a brief earthquake if underground, or millions of tiny radioactive bubbles rising to surface if underwater).

What is the radius of a nuke?
Blast radius (and other effects) varies with:yieldburst height/depthterrainif subsurface, the material around the burstinversion layer present or absentetc.Using my Nuclear Weapon Effects circular sliderule, assuming distance for 1 psi maximum overpressure as "blast radius":A 1 KTon yield at optimum burst height on flat terrain: 1.35 miles.A 1 KTon yield surface burst on flat terrain: 0.75 miles.A 20 KTon yield at optimum burst height on flat terrain: 3.64 miles.A 20 KTon yield surface burst on flat terrain: 2.00 miles.A 10 MTon yield at optimum burst height on flat terrain: 29 miles.A 10 MTon yield surface burst on flat terrain: 15.8 miles.1 psi maximum overpressure was selected because structural damage to buildings due to blast wave and wind is minor, however glass, plaster, etc. damage will be much further out.Except for thermal burns, most immediate radiation effects are also contained within this radius.
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.
What is the blast radius of a mark 82 bomb?
Difficult to answer- depends on your definition of "blast radius", and how the weapon is fused- air burst, surface, delay. Blast radius can refer to damage to structures, armored vehicles, troops in the open, or troops under cover. Damage is caused from fragments, heat, and overpressure. Troops in bunkers may survive detonations at 50 meters, but troops in the open at 400 meters would be at hazard. Reinforced concrete buildings at 25 meters would sustain damage.
Destructive radius of a five kiloton nuclear explosion?
The destructive radius of a five-kiloton nuclear explosion is typically around 500 to 700 meters, resulting in significant destruction of buildings and infrastructure in the immediate vicinity of the blast. This radius can vary depending on factors such as the height of the explosion, terrain, and weather conditions. However, it's important to note that the effects of a nuclear explosion extend far beyond the immediate blast radius due to factors like heat, radiation, and fallout.
Why was airburst chosen instead of surface burst for World War 2 nuclear bombs?
Greater damage from blast and thermal radiation.
What type of atomic burst is deadlier air burst surface burst or subsurface burst?
An air burst is typically the deadliest type of atomic burst as it creates a large area of devastation due to the shockwave, heat, and radiation released. A surface burst can also be very deadly as it creates more fallout, causing widespread contamination. A subsurface burst is usually less deadly as the ground can help contain some of the initial blast and reduce the immediate impact.
How is a blast radius calculated?
See the book The Effects of Nuclear Weapons for equations. My copy came with a circular slide rule that calculates that for optimal altitude airburst and surface burst over a yield range of 1 KTon to 10 MTon. It also calculates many other effects.
Which is better Dragon Ball Z raging blast or Dragon Ball Z burst limit?
Burst Limit had better reviews than Raging Blast.
What is the blast and EMP radius of a 20KT nuclear warhead detonated at surface level?
It really depends on the terrain surrounding the blast and the altitude of the blast. EMP would be negligible, as those effects are only seen during very high altitude detonations (in space or upper atmosphere, for instance). I'd have to say a safe answer of one to two miles if you're including overpressure capable of damaging a building or less as a general rule for a weapon of this yield. According to my circular slide rule nuclear weapons effects calculator, the blast damage radius (defined as 1 PSI maximum overpressure) for a 20KT surface burst is 2 miles, assuming level terrain. It would leave a crater in soil 0.0145 miles (25.52 yards) deep and 0.06 miles (105.6 yards) radius at the lip, or in rock/concrete 0.012 miles (21.12 yards) deep and 0.05 miles (88 yards) radius at the lip.
