There can't be any limit to airborne contamination, either gaseous or small particles, since we live in one world. The Chernobyl leak was truly massive, and contamination was noticed as far away as Scotland, though there it presented no direct threat to people, the effect was only apparent in meat from animals grazing in open areas, and the solution was simply to ban this meat for a period. Something similar happened in northern Scandinavia where reindeer meat was contaminated. This affected those farmers who keep and sell reindeer, but apart from that no real worries. If you are thinking of the recent Japan experience, it is too early to know the scale of what is happening, but assuming the main vessel and secondary containment are intact, there will be a much more limited release of activity as the plant operators get a grip on the situation. It will be more like the Three Mile Island event in 1979, a lot of fuss but not much tangible effect. Still, it does raise questions over building nuclear plants in Japan and similar regions. I don't know for sure, but I guess the strength of this earthquake exceeded the design basis event. I would be surprised however if there is any concern more than 100 km from the plant.

How are atomic bombs made?
Much of the design particulars are top secret-Q but basically you need a mass of fissile material (usually plutonium) large enough to be able to reach supercritical mass and support an uncontrolled nuclear reaction. The explosion is triggered by compressing the plutonium by an implosion to assemble the initially subcritical mass into a supercritical mass rapidly (a couple milliseconds). once the material reaches supercritical mass, a neutron source is fired through it to start the reaction at the optimal time. about 4µs to 7µs later the bomb explodes. The longer the design is able to hold the bomb together, the higher the yield when it does disassemble.
What are some pros and cons of plutonium?
Pros for plutonium: • explosive in nuclear weapons • nuclear fuel in nuclear power reactors • the isotope 238Pu is used as energy source in spacecrafts or other applications (radioisotope thermoelectric generators); the chemical form is plutonium dioxide. • neutron generator, as Pu-Be source Cons for plutonium: * very radioactive * very toxic * able to reach criticality
Pros and cons of plutonium?
Applications of plutonium: • explosive in nuclear weapons • nuclear fuel in nuclear power reactors • the isotope 238Pu is used as energy source in spacecrafts or other applications (radioisotope thermoelectric generators); the chemical form is plutonium dioxide. • neutron generator, as Pu-Be source Disadvantages of plutonium: - plutonium is radioactive - plutonium is toxic - plutonium is flammable - plutonium can reach a critical mass
What is a steam of a flower for?
A flower stem serves to support the flower, allowing it to reach sunlight for photosynthesis. It also transports water and nutrients from the roots to the rest of the plant, as well as sugars produced during photosynthesis from the leaves to other parts of the plant.
What are the advantages and disadvantages for using plutonium in generate electricity?
Applications of plutonium: * nuclear fuel in nuclear power reactors; can contribute to use uranium-238 which is fertile.Disadvantages of plutonium:- plutonium is radioactive - plutonium is toxic - plutonium is flammable - in some conditions (of mass and geometric form) plutonium can reach the critical mass
If a nuclear-armed ICBM is destroyed mid-flight will the nuclear explosion take place?
Generally, no. The arming mechanism for the warhead is designed to arm only within reach of the target.
Will the nuclear explosion reach Vietnam?
I assume you are talking about the current situation in Japan, in which case there is no surety that the reactors will degrade fully, much less detonate. Second, were they to create a catastrophic explosion, there is no way the blast itself would reach Vietnam. There would be, however, a fairly good chance that offset radiation or even a portion of the fallout from such an explosion could reach continental asia, depending on the wind conditions.
If the nuclear power plant in palatka Florida exploded will it reach Ocala Florida?
According to Wikipedia's sources, the power plant in Palatka, Seminole Generating Station, is a coal burning power plant. It only appears to be nuclear because of the cooling towers that are iconic of nuclear power plants but can be used coal fired power plants. I would have to imagine that the blast from a coal power plant, if exploded, would not travel the 40 or so miles to Ocala.
How fast does a Nuclear Warhead of Russia travel?
A nuclear warhead launched from Russia can travel at speeds of up to 15,000 miles per hour or more, depending on the specific type of ballistic missile used. These missiles are designed to travel at hypersonic speeds to reach their target quickly and with minimal chance of interception.
What is a super combine explosion in halo reach?
using a needler continuously on an enemy to make a pink explosion!
Can a nuclear weapon reach US soil?
Yes it can. The distance from Russia to the U.S is 9000km, r-36 Russian missile could travel 16000km in 30mins(and it is a 1967 one).
How hot is a nuclear explosion?
The explosion itself is not the source of the heat emitted from a nuclear detonation. Instead the heat is the source of the explosion. Compare this with thunder following a lightning strike. In the nuclear bomb temperatures of about 20 million degrees fahrenheit are produced causing the emission of x-rays which ionizes the air preventing any more light or IR emission until the bomb cools enough that it no longer is emitting x-rays. In lightning the temperature of the ionized conducting air channel is only about 90000 degrees fahrenheit.As to the temperature of things around the fireball from a nuclear detonation, directly beneath the fireball temperatures can reach about 7000 degrees fahrenheit. To give an example by which to compare this heat, free flowing magma, or melted rock, averages a high of 4000 degrees fahrenheit.
How do nuclear reactors meltdown?
The nuclear core goes into a process known as 'meltdown' if it becomes too hot. For a reactor to reach critical temperature something serious has to malfunction, this could be a lack of water inside the reactor, pressure loss inside the reactor or no control rods inside the reactor, all of these faults could lead to severe damage to the reactor core and a possible lead to a thermal explosion(not a mushroom cloud explosion).
What is the Fahrenheit temperature of a nuclear weapon?
About 180 million degrees Fahrenheit upon detonation, which is some 10,000 times hotter than the surface of the sun.
How do you make a never ending explosion on halo reach?
you dont stupid
Who would win Russia or amarica?
In a non-nuclear war, The United States has the advantage of superior military power, and technology, and having Alaska as a staging ground. While Russia, has no advantages. If Russia had invaded, then they would have to march through Canada first before being able to reach Mainland USA, and the Canadians wouldn't put up with that. While if the US invaded Russia, The Russians have the advantage of the Russian winter, knowing their battlefields, and having almost no route from Vladivostok, to Moscow. In a Nuclear war, Neither, both countries would be so damaged from nuclear warfare, that they would both be nothing but wastelands. But in a non-nuclear war, it all comes down to the tactics used.
Speed of a nuke?
It depends on the delivery mechanism. If dropped by a modern jet bomber, a nuke can acheive low supersonic speeds. If on a intercontinental ballistic missile, a nuclear weapon can reach speeds exceeding 15 times the speed of sound, or several thousand miles per hour.
