What countries have or have use Dirty bombs?
so called "dirty bombs" cannot be built and stockpiled like nuclear weapons can. they must be assembled shortly before use. a "dirty bomb" is simply a conventional bomb wrapped in radioactive waste, the detonation of the conventional bomb scatters the radioactive waste thus making it "dirty". the problem with making a "dirty bomb" is that radiation from the radioactive waste will almost certainly kill anyone involved in the assembly of the bomb.
countries are very unlikely to seriously consider making such bombs, only terrorist groups are likely to attempt it.
nuclear missiles and nuclear gravity bombs are entirely different delivery mechanisms and do not change by being carried on a different aircraft. missiles are launched or fired, gravity bombs a passively dropped.
- The first staged hydrogen bomb was developed by a team at Los Alamos, NM in 1952. It was not a practical bomb as it used cryogenic liquid deuterium-tritium and required a refrigeration system larger than itself to keep it cold.
- The first practical "hydrogen" bomb was developed by a team at Arzamas-16 in the USSR in 1953. It used dry lithium deuteride, however did not use staging like the 1952 US bomb did so its yield was limited. It was likely done mostly for propaganda purposes. In modern terminology it would be considered a dry boosted fission bomb, not a fusion (hydrogen) bomb.
- The first practical staged hydrogen bomb was developed by a team at Los Alamos, NM in 1954. It used dry lithium deuteride.
- The second practical staged hydrogen bomb was developed by a team at Arzamas-16 in the USSR in 1955. It used dry lithium deuteride.
What percent of the world's countries have nuclear weapons?
As of November 4th 2013 there are 9 countries that possess nuclear weapons -- United States, Russia, France, United Kingdom, China, Pakistan, India, Israel, and North Korea. Depending on one's definition there are between 193 and 250 countries currently, which means approximately 3.7 to 4.7% have nuclear weapons.

What country has exploded a nuclear bomb in space?
The U.S. exploded more than half a dozen hydrogen bombs in space. They produced strangely colored glowing clouds right after the explosion and dangerous radiation belts that remained for weeks (causing auroras). Several shots done over the Pacific Ocean triggered electrical blackouts in Hawaii from EMP. One shot actually delayed a Gemini mission launch to avoid the chance of exposing the astronauts to high levels of radiation.
Why North Korea start fight with USA about nuke or something?
Because recently, North Korea's leaders have been small, fat, wimpy guys. They probably think that missiles and nuclear bomb development makes them appear to be big tough guys. This is called, "Compensating".
How did the USSR intend to protect its self?
The USSR intended to protect itself by building a huge army and by developing nuclear weapons.
What is the name of people who make nuclear weapons?
There is no specific name for people who create nuclear weapons.
Limitation or reduction of weapons?
The United States and USSR actually had reached an agreement to negotiate on the limitations and reductions of both the strategic offensive and defensive systems.
How many war planes does the U S have?
Total aircraft is estimated at about 13,683. This includes attack and support aircraft. The number may seem small to some but the destructive power of the weapons have increased to a point that the destruction caused by 100's of warplanes in WW2 can now be achieved by just a handful. That doesn't include nuclear weapons, which if used by aircraft could result in entire nations being destroyed on one mission.
When was Chernobyl Nuclear Power Plant sarcophagus created?
Chernobyl Nuclear Power Plant sarcophagus was created in 1986.
When did America's monopoly on nuclear weapons end?
1949 when the USSR tested their first atomic bomb.

Would you want to survive a nuclear disaster?
No, I don't think I would. The radiation after the nuclear bomb went off would be extraordinary, and after living in it, it would be a painful way to die. I think I would rather be at ground zero if the nuke was to go off. No muss, no fuss, and a quick death.

The US performed the first nuclear weapon test on July 16, 1945.
Why can you not make a hydrogen bomb?
Scientists have long tried to make a pure Hydrogen weapon, the problem with all the designs that have been attempted is the compression of the Hydrogen material to its flash point. Hydrogen can be compressed under great pressure to make a functioning weapon; however, the only way we have managed to do this practically is through the Teller-Ulam design. This design uses a nuclear fission weapon to compress the Hydrogen within a secondary device to start a fusion reaction.
Without the ability to use a fission weapon to ignite the Hydrogen, we do not have a way to compress it to its flash point. There are still design attempts that have been circulated to make a pure fusion Hydrogen weapon, but none have been tested and the problem of getting Hydrogen to flash is always the founding problem. Most designs have been abandoned, and there are currently no known developmental plans by the United States to Pursue this design.
What was a major fear that people in postwar America had about the use of nuclear weapons?
The Hydrogen bomb was a major fear that people in postwar America had about the use of nuclear weapons.
How many nations have used nuclear weapon in an aggressive manner?
One, the US to end WW2.
There has been alot of saberrattling since then with them, but no use.
What year did the US spend the most money on nuclear bombs?
I don't have the exact year, but it was during Ronald Reagan's term as president.
Why were nuclear weapons even considered to be built?
Fear that someone else would build them first and attack the US or our allies.
During World War 2 the "someone" was Nazi Germany and the nuclear weapon was the atomic fission bomb, during the Cold War the "someone" was the USSR and the nuclear weapon was the hydrogen fusion bomb.
The US clearly won the race with Nazi Germany as their project derailed early due to multiple errors and oversights by their scientists and the work was redirected away from bombs to prototype reactors, however the US and USSR both developed and fielded practical megaton range hydrogen bombs in the same year: 1955, making that race effectively a tie!!!
