Well i did some rough estimates...prob be like 56 miles
A 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.

What would be the radius of a 300 megaton bomb?
Sorry, my nuclear bomb effects circular slide rule only goes up to 100MTon yield.
What is the radius of distruction from a nuclear war head?
Depends on how heavy the war head is and where its detonated (how high/on the ground etc). The actual blast of a 25 megaton war head would be around 7 miles. Theres also the thermal radiation, nuclear fallout and other things to consider in terms of long term damage
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.
What was the radius of the B53 bomb explosion?
The last live B53 munition began diasassembly in Texas today, 23 October 2011. This was the largest nuclear weapon in the US Arsenal at 9 megatons. The following is a quote from the Wikipedia article on the B53. The yield is projected- not all nuclear weapons were live tested in the open- Effects Assuming a detonation at optimum height, a 9 megaton blast would result in a fireball some 4 to 5 kilometers (2.5 to 3 miles) in diameter.[10] The radiated heat would be sufficient to cause lethal burns to any unprotected person within a 28.7 kilometers (17.8 mi) radius (995 square miles (2,580 km2)). Blast effects would be sufficient to collapse most residential and industrial structures within a 14.9-kilometer (9.3 mi) radius (300 square miles (780 km2)); within 5.7 kilometers (3.5 mi) virtually all above-ground structures would be destroyed and blast effects would inflict near 100% fatalities. Within 4.7 kilometers (2.9 mi) a 500 rem dose of ionizing radiation would be received by the average person, sufficient to cause a 50% to 90% casualty rate independent of thermal or blast effects at this distance.
How big is an Atomic bombs explosion?
Depending on the yield and type of detonation, a nuclear weapon detonation can have a radius of several hundred feet to several hundred miles.Nuclear weapons have been developed of the size as small as a small suitcase, to weighing several tons.An example of a typical Cold War era weapon in the five megaton range with a surface burst would produce a blast crater approximately a mile and a half wide, and half a mile deep, with a blast radius of about fifty miles. Consider that for a moment, then consider that the Soviet Union at its height claimed to have developed a weapon with a selectable yield that could be as large as 100 megatons. They did test the device, air burst near the Arctic Circle in the 1950's, and the effects were felt several hundred miles away.A little bit more about yield and burst:Nuclear weapons have yields of under 1 kiloton (the M-28/29 Davy Crockett Tactical Nuclear Recoiless Gun--also referred to sometimes as a "nuclear grenade"--circa 1955, fired the M388 warhead with a yield of .001 - .002 kiloton) to at least 50 megatons (the Soviet Tzar Bomba was said to have a yield of100 megatons). A one megaton device is relatively small but still can cause tremendous devastation. The bombs dropped on Hiroshima and Nagasaki were in the 20 kiloton range (Fat Man was larger, estimated at around 22 kiloton, Little Boy was estimated at around 15 kiloton). During the height of the Cold War, much of the US would have been expected to receive missiles of at least 5 megaton payloads. A five megaton surface burst blast will leave a crater approximately 1½ miles across and ½ mile deep. The blast range of such a weapon would send a wave outward at about 250,000 feet per second (initially...quickly dropping to approximately the speed of sound) for a thirty to fifty mile radius, depending a bit on landforms, falling off in speed as it expanded outward of course.This leads of course to the second element, burst:There are three types of nuclear burst: air, surface, and subsurface. The type of burst that causes the greatest amount of physical damage is a surface burst device. This is a weapon that is designed to detonate at impact. The greater destructive force is caused by such close proximity to the ground, where the detonation is concentrated into the ground and ejects debris upward and out in the dramatic "inverted bowl" form that can be seen in much of the test detonation footage.The second least physically devastating form, or potentially lessor physically devastating form is the air burst. An air burst detonation transmits the force of the blast equally around it. Depending on the altitude at which it fires, an air burst may cause great to no physical damage to people or structures on the ground. Again at the height of the cold war, it was estimated that two Hydrogen devices detonated at high altitude over the US would have caused an EMP (Electromagnetic Pulse) that would have fried all electronic devices in the US, Mexico, and much of Canada. However, even a small hydrogen device fired at lower altitude could create a blast wave that would essentially scrub the ground clean in the blast radius, but would leave no crater, or a minimal crater in its wake. This was the idea essentially behind the Neutron Bomb; one that when detonated left most structures intact outside of the immediate blast zone, but killed by the high radiation it released, leaving the territory essentially clean for occupying troops.The least devastating form, or least readily visibly devastating form of blast is the sub-surface detonation. Sub-surface devices were developed for attacking underground, primarily "hardened" targets such as bunkers and silos. A small to medium subsurface burst will effectively destroy an enemy stronghold several hundred feet below ground but can leave the surface largely undisturbed. Larger detonations in the 100's of kiloton to the megaton range can leave large subduction zones where the surface above the detonation drops to fill in the void left by the detonation. This of course depends again upon the yield, and also the depth at which the detonation is set.

What is the blast radius of 250 gallon propane tank?
The blast radius of a 250 gallon propane tank would be 100 yards
What insects can survive a nuclear blast?
A direct nuclear blast - nothing. However it is said that cockroaches would possibly survive radiation where other animals would be killed.
Compare the energy of a 1-megaton hydrogen bomb to the energy released by a major earthquake?
A magnitude 8 earthquake releases approximately the same energy as a 15 megaton nuclear explosion (e.g. Castle Bravo test in 1954). This is the same as fifteen 1 megaton nuclear explosions. Note: the photo above is of a 0.5 megaton nuclear explosion.
What are the HARMFULNESS caused by nuclear blast?
The blast effects (which is all the question as worded asks about) would be the same as the blast effects of a weight of TNT identical to the nuclear bomb's yield (by definition). However a nuclear bomb has additional effects that the TNT doesn't, but as this question only asked about blast effects, I won't visit them.
Would you survive a nuclear bomb in a house with all the windows closed?
Unlikely, if within the blast radius most houses of conventional construction would be flattened, if within the thermal flash radius most wooden houses would also ignite and burn, if within the high radiation radius you might die before your house burned and flattened. Windows closed or opened.

What is stronger a bomb or a tornado?
Apples and oranges. The most destructive tornado on record is an F5. Several have hit locations in the central US over the past decades. One of the largest had a base of over a mile. That is it created a one mile swath of destruction. There are generally two classes of bombs: conventional and nuclear. The largest conventional bomb was built by the US, the MOAB (GBU-43/B Massive Ordnance Air Blast, commonly referred to as the Mother of all Bombs). MOAB is what we call a Fuel Air Explosive (FAE), that is it uses two explosive charges--one to disperse the fuel mixture and a second to detonate it. MOAB has an unclassified blast yield of 11 tons. Since MOAB's development in 2003, Russia has made claims of building and testing the Father of all Bombs (Aviation Thermobaric Bomb of Increased Power (ATBIP)). FOAB has an estimated yield of 44 tones. MOAB has a blast radius of 500 feet, ATBIP has a blast radius of 1,000 feet, both well under that one mile base of an F5. The second type of bomb, nuclear is another matter. The smallest yield nuclear weapon developed is a toss up between the M-28 or M-29 Davy Crockett Weapon Systems, a vehicle or tripod mounted tactical nuclear recoilless gun with a yield of 10 to 20 tons, and similar sized artillery rounds. The blast radius of such a device would have been similar to that of the MOAB but less than that of the ATBIP. The largest nuclear device alleged to have been built was a 100 megaton thermonuclear device for the Soviet (former Russian USSR) military. Although none are believed to have been tested, the blast radius of such a device is nearly unimaginable. To put this into perspective, the most common strategic nuclear device was in the 5 megaton range. Such a device detonated above ground at about 200 feet would create a crater roughly 1.5 miles wide, and half a mile deep, essentially vaporizing everything within that diameter. Blast damage would radiate out from ground zero well past the speed of sound flattening and burning everything within about a 30 to 50 mile radius, diminishing the level of damage as it radiated outward. At about 60 to 70 miles, the blast wave would be experienced as a high wind. Additionally, everything down wind for roughly the width of the western hemisphere would be irradiated. So, in short, one can run from a tornado, and find shelter in something as simple as a drainage culvert. One does not outrun MOAB, FOAB, or Grandpa Nuke.
What the effect of a nuclear explosion?
Radiation taints the ground, everyone in the blast radius of the initial explosion would be decimated. Look at Hiroshima, Japan, or Nagasaki, Japan (not sure on spelling), they were bombed by an atomic bomb, and still have radiation poisoned in the ground.
What was the biggest nuclear explosion?
The biggest nuclear explosion in history was a 50 megaton (equivalent to 50 million tons of tnt) bomb tested by the soviet union called the "Tsar Bomb". nobody was killed in the blast. the previous answer was completely false, Chernobyl was one of the smallest nuclear explosions in history, smaller than the Hiroshima bomb, which was only 17 kilotons (17 thousand tons of tnt, almost 3000 times smaller than the Tsar Bomb). People were mainly killed by the radiation. The blast didn't even kill everybody inside the actual plant (I'm not sure how many were killed in the blast, if somebody would like to add to this)
