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.
Increasing positive nuclear charge
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.
It depends on how big your head is.
The answer will depend on whether the larger cylinder is 4 times larger in terms of radius, cross-sectional area, or volume. If radius, multiply the smaller radius by 4. If cross-sectional area, multiply the smaller radius by 2. If volume, you do not have enough information.
It depends on what you mean by "big". It has a radius of 600 inches.
35km
The fireball was roughly 1500 feet in diameter (750 feet in radius).Blast damage was found at 10000 yards (30000 feet) to some of the bunkers.The blast was heard hundreds of miles away.
That depends on what you're referring to: The fireball radius (the nuclear explosion itself), the total anhiliation range radius, and etc. For example, the bomb launched on Hiroshima had a fireball of several hundred feet in radius, a 1km total destruction range radius, and severe damage for miles. For firepower bombs (nuclear bombs made for power show & not effectiveness) The Tsar bomba of USSR had 50~55 megatons of TNT firepower, a fireball with 1km+ radius, total destruction for miles, and created a sound shockwave that could be heard in Norway/Other far Northern European areas. Modern nuclear weapons don't have a single blast radius; the U.S. developed M.I.R.V.s (cluster nuclear bombs) that spread apart to create a shotgun blast of multiple nuclear explosions.
That is approximately proportional to the cubed root of its yield. This is also true of conventional bombs.
This really depends on a number of factors, such as the yield of the weapon, the detonation altitude, and the terrain.
Yes the tsunami did trigger the nuclear blast because the water got into the nuclear reactor and buggered it up
The blast radius of a 250 gallon propane tank would be 100 yards
no
Well i did some rough estimates...prob be like 56 milesA blast radius is equal to the square root of the megatonage. A 1 megaton bomb has a blast radius of severe damage of about 4 miles. Therefore a 200 megaton bomb (14 being about the square root) would have about a 56 mile radius. Though direct exposure to the explosion at that distance could probably still cause severe burns and it would probably cause damage as much as 200 miles out.
There are three forms of damage caused by a nuclear detonation:BlastFireRadiationOf the three, blast and fire are typically the most devastating over the largest area. Radiation, however, is the longest lasting and depends on the nuclear components of the device.Typically, destructive distance is referred to as the blast radius. The bomb dropped on Hiroshima, Little Boy (the benchmark for most of what we know), had a blast radius of one mile. That is that the wave from the detonation of the device at about 500 meters altitude spread out at about the speed of sound for one mile from ground zero (a two mile diameter). The blast radius is directly related to the yield of the device. Little boy being relatively small, about 40 kt (kiloton). The average yield at the height of the Cold War was about five mt (megaton). This yield device, with a surface burst detonation (the least destructive--compared to subsurface or airburst) produces a blast radius of about 20 miles.In addition to the blast radius is the area of firestorm and high level radiation which is roughly twice that of the blast radius.There are a number of nuclear blast emulators available on line. One is linked below.Little Boy was about 15 kilotons, not 40 kilotons. Fat Man was a little more than 20 kiloton.
The Hiroshima and Nagasaki bombs were firecrackers compared to a standard warhead today. The Hiroshima bomb was about 20 kilotons - the equivalent of 20,000 tons of TNT. Subsequently thermo-nuclear devices were perfected, and yields of 50 MEGAtons are attained. Big enough to annihilate everything for a fifty to one hundred mile radius from the blast. So big in fact that its pointless to develop anything stronger, as existing weapons will have a blast radius extending beyond the atmosphere of the planet, and any additional power would be largely vented into space. In the 1950s US Army doctrine called for preparing for a "nuclear" battlefield. As part of that nuclear artillery pieces were developed, to fire out limited-yield tactical nuclear shells about ten miles, with a small enough blast that the gun crew could survive. Similar nuclear ammunition was developed by the Navy to be fired from the main battery of battleships. Today such limited-yield tactical nuclear weapons are mounted on short range missiles. There's also the neutron bomb, which emits mostly radiation to kill all living creatures without the messy blast and fire, leaving infrastructure intact for the benefit of ground forces moving in afterward.
standard blast radius is around 3-8 feet
