  Nuclear fallout - Wikipedia, the free encyclopedia
Fallout is the residual radiation hazard from a nuclear explosion and is named from the fact that it "falls out" of the atmosphere into which it is spread during the explosion.
Nuclear weapons are relatively inefficient in their use of fissionable material, usually only 2%-40% of the fissionable material undergoes fission and much of the uranium and plutonium is dispersed by the explosion without undergoing fission.
The radiobiological hazard of worldwide fallout is essentially a long-term one due to the potential accumulation of long-lived radioisotopes, such as strontium-90 and caesium-137, in the body as a result of ingestion of foods incorporating these radioactive materials.

 Nuclear winter - Wikipedia, the free encyclopedia
Nuclear winter is a hypothetical global climate condition that is predicted to be a possible outcome of a large-scale nuclear war.
It is thought that severely cold weather can be caused by detonating large numbers of nuclear weapons, especially over flammable targets such as cities, where large amounts of smoke and soot would be injected into the Earth's stratosphere.
The combination of darkness and killing frosts, combined with high doses of radiation from nuclear fallout, would severely damage plant life in the region.

Fallout is radioactive dust created when a nuclear weapon explodes.
The residual radiation hazard from a nuclear explosion is in the form of radioactive fallout and neutron-induced activity.
The radiobiological hazard of worldwide fallout is essentially a long-term one due to the potential accumulation of long-lived radioisotopes, such as strontium-90 and cesium-137, in the body as a result of ingestion of foods incorporating these radioactive materials.

 WebMD - Exploring the Unthinkable: Nuclear Fallout
If a nuclear weapon were detonated there is a tell-tale flash followed by a shock wave blast; the bomb, if detonated near the ground, would cause a crater, and material and earth within the crater would be sucked up as fallout and then distributed over a wide area.
In the case of a nuclear power plant accident, there may be some debris, but I don't believe the radioactive plume would be visible downwind of the site; if the plant were on fire there would be smoke visible, once dissipated there would be no way to detect this visually.
In the case of a nuclear reactor, there are plausible ways in which a group of determined terrorists could attack a plant and cause a massive release of radiation.

 11 Steps to Nuclear Fallout Survival
Nuclear explosions in the air rather than on the ground are more likely to produce a greater number of serious burns through the heat flash.
Because fallout is carried so far and covers such a large area, it could be the greatest danger to the largest number of Canadians in a nuclear war.
Fallout is a health hazard which will require countermeasures for personal and family protection including assessment of radiation and advice and instructions to those in shelter.

 In These Times * Nuclear Fallout
Iodine-131 was dropped as fallout across dairy country, where it was consumed by cows and goats and concentrated in their milk.
The body count from fallout is insidious, largely hidden in the slow but relentless accumulation of cancers, such as thyroid (2,500 deaths), leukemia (550 deaths) and radiogenic cancers from both internal and external exposure (17,050 deaths).
The fallout statistics also don’t account for the deaths and illnesses of other civilians, including uranium miners, nuclear plant workers and others who live near Hanford, Washington, and Rocky Flats, Colorado, where nuclear weapons were produced until the late ’80s.

BNFL, employers of 10,000, custodians of the nation's plutonium and uranium stockpiles and an ever-growing mountain of nuclear waste, is bankrupt.
In effect, all the nuclear facilities owned and operated by BNFL would be taken back into the direct public ownership of a quango.
It is BNFL rather than the privatised arm of the nuclear industry British Energy, which wants no part of it, that has been canvassing the government heavily to build at least a dozen new nuclear stations.

 Nuclear Fallout
Nuclear fallout is the particles of matter in the air made radioactive from a nuclear explosion.
The rate of fallout largely depends on the altitude of the nuclear explotion and to a lesser extent the magnitude of the explotion.
It was observed that from 1963 to 1965 the annual dose of global fallout dropped 50%.

 "Nuclear fallout"
The more than 120 French nuclear tests conducted there have vaporized spheres of rock hundreds of feet across, pocking the bedrock like Swiss cheese, and filling the holes with nuclear waste.
The French, however, say that while one test is for a new (though already designed) submarine missile, the main reason they need these tests is to maintain the safety and reliability of the weapons in their stockpile.
"This would close the gap between nuclear and conventional warfare," he says, setting up the possibility of nuclear weapons being used for the first time in war since Nagasaki.

Nuclear electromagnetic pulse is an immediate effect from larger nuclear weapons which acts to destroy electronic devices at great distances with a lightning-like zap effect.

While only a few of the potential nuclear threats above would entail blast damage, all would involve possible radiation exposure and a few with actual radioactive fallout that the wind had then carried far from the original scene of the incident.
Half of all the energy released by nuclear explosions is in the form of blast and shock and about 35% is in the form of heat.

More than 2,000 nuclear tests have been conducted worldwide since the first nuclear bomb was built in the Manhattan Project in World War II, but the CDC/NCI study considered only those above-ground tests that took place between 1951 and 1962.
She noted that officials in the 1950s notified suppliers of photographic film of expected fallout patterns so they could protect their film, but did not share the information with milk producers, for example.

A generation ago, as a nuclear disaster unfolded in central Pennsylvania and 140,000 people fled the area, pharmaceutical executives were rousted from bed in the middle of the night by a plea for help.
But if a nuclear disaster were to occur today, whether by terrorist strike or otherwise, the government might well be in the same position it was in1979, trying to scare up supplies of the drug on short notice.
The nuclear power industry, which stocks potassium iodide to protect workers in its plants, has long opposed a large public stockpile, carrying as it would the implication that nuclear power might be unsafe.
