Nuclear Weapons

Today, if any country decided to send a missile over to our country, we would know via satellite that they had fired (in a matter of mere seconds). By knowing they are sending a nuclear bomb to our country, we would fire one them. This would mean a nuclear fallout; our bombs are at least thirty times stronger than the bombs released at Hiroshima and Nagasaki in 1945. This keeps any country from using nuclear weapons on each other for fear of nuclear fallout.

The first Nuclear weapon was created by a team of American Scientist's, known as the Manhattan project. It was first tested and used in 1945, not long before we used them on Japan.

like the last guy said its enough power to take off some guys head

first new clear weapon made is 1996

Yes, yes, yes. Probably safer designs should be developed than current ones, but absolutely yes.

You likely mean to limitation and disarmament of nuclear weapons. This would be the Nuclear Non-Proliferation Treaty (NPT).

Depends what country - nuclear A-bombs used to be deployed from planes (they still are, just not as much). H-bombs tend to be ICBMs (Inter-Continental Ballistic Missiles) - basically huge rockets tipped with one or more nuclear warheads.

Size? Again, depends what country - the USA, Russia and China probably have nukes that could reach any country. Britain, France and possibly Israel have weapons that could probably cross half the globe and cause significant damage. Countries like North Korea, India and Pakistan have short-range warheads with lower yield (in the kilotons).

There are two operating nuclear power plants in Alabama, but there is a third that was partially built and is being considered again. The Brown's Ferry plant has been producing power at Athens, Alabama since December of 1973. The Joseph M. Farley Nuclear Generating Station at Dothan, Alabama began operations on December 1, 1977. The incomplete plant is the Belefonte Generating Station at Hollywood, Alabama.

The effects of nuclear radiation exposure depend on the dose received and can vary from immediate death to long-term health issues. Acute high doses can cause immediate organ failure and death within days to weeks, while lower doses may lead to long-term health problems such as cancer. It's important to seek medical treatment and follow safety measures to minimize exposure.

nuclear fusion

YES!

No. A nuclear weapon requires a critical amount of highly enriched fuel to be rapidly brought together to cause a sudden explosion. Nuclear plants use low enriched fuel which could never cause a nuclear explosion, and this fuel is dispersed through the reactor in any case so it could not suddenly come together.

Any nuclear plant explosions (like Chernobyl) are caused by the presence of high pressure steam and water circuits, not the fact of it being a nuclear plant, though certainly if there is an explosion of a pressure circuit and hence a loss of coolant, and disruption of the nuclear reactor, radioactivity may escape from the plant. This is the chief preoccupation of designers and operators, to keep the plant safe and prevent this ever happening.

The risk of an accidental or inadvertent nuclear launch or accidental explosion is unacceptably high. On the other hand, The B61-11 is categorized as a deep earth penetrating bomb capable of "destroying the deepest and most hardened of underground bunkers, which the conventional warheads are not capable of doing wich is good keeping civlitians for getting hurt compared to the nuclear bombs used in ww2.

No bombs were actually used during the Cold War. That was why it was not a hot war.

The Japanese cities of Hiroshima and Nagasaki .

It could be either one depending on the device used in the weapon. Some bombs and missile warheads were the same device and thus had the same yield.

1949. This was a nasty surprise to the US, who had estimated that it would take the Soviets several more years. But Soviet spies had been very successful and lots of information was supplied by Julius and Ethel Rosenberg, who were executed as spies by the US.

The UK was the third country to obtain nuclear weapons, after the US and the USSR. The UK had its first successful nuclear weapon test in October 1952, a plutonium warhead similar to the one dropped on Nagasaki.

It means the kind of devastation that a nuclear war would produce.

In any war ,the push is always on to develop more powerful weapons. Even in relative peacetime, civilised countries cannot relax their vigilance or rogue governments like North Korea and Iran will continue to try to become more powerful and develop their own better weapons.

In the cities of Hiroshima & Nagasaki.

No, but they were the center of it. The Cold War was never a real war, and there was no fighting o nuclear exchange involved. Basically, it was a time of tension between the superpowers. The Arms Race and the Space Race contributed to this tenson. A notable event was the Cuban Missle Crisis, where the Soviets were storing missiles in Cuba in case of an attack on the US. The US threatened to launch ballistic missiles at them from Turkey, so the Soviets removed the Cuban Missiles. Long story short, the Cold War was a stand-off, like two people pointing guns at each other to see whos going to crack first and start the fight.

No. After WW2 nukes were not banned, they were more like mass produced by the US and the USSR, followed by UK and France.
