No, it is perfectly legal as long as it is used on your own property.
Yes, of course. They have had them since 1949.
Russia developed its own nuclear program, and was aided by espionage.
A bit over 3500 active units, with parts from a similar number of dismantled units that could be rebuilt relatively quickly if needed.
Officially no, nobody sells them. You would have to make your own. But even the needed fissile material is not sold! However, that said there might be a secret black market selling either the material or finished bombs. That is part of the fear of North Korea (already known to have tested bombs) or Iran developing nuclear bombs, that they would sell them.
yes, some people research and try to make nuclear bombs in their own houses.
No, they made their own. After their first test in 1949 (which was a copy of the US Fatman based on espionage) they designed them on their own also.
The atomic bomb has been replaced by the nuclear bomb. This type of weapon was first developed by the US in the early 1950's. Soon afterwards, the Soviet Union also created their own style of nuclear weapons and bombs.
Russia developed its own atomic bomb by conducting extensive research and espionage on the American nuclear program. They successfully tested their first atomic bomb on August 29, 1949, becoming the second country to possess nuclear weapons after the United States.
The term "parmanu bomb" refers to nuclear weapons. The exact number of nuclear weapons required to destroy a country like Pakistan depends on various factors, including the targets, yield of the bombs, and the desired level of destruction. Pakistan is known to possess its own nuclear arsenal, which serves as a deterrent against such attacks. The use of nuclear weapons carries catastrophic humanitarian and environmental consequences, making their use highly contentious.
Ernest Rutherford did not make the nuclear bomb. He was a physicist who conducted pioneering work in the field of nuclear physics, particularly on the structure of the atom. The development of the nuclear bomb was primarily led by other scientists during the Manhattan Project in World War II.
It is part of Russia.
