Absorbed into atmosphere or into ground as radiation.
Most debris from a nuclear weapons test consists of radioactive materials in the form of soil, rock, and other materials that were vaporized or melted during the explosion. This debris can be a significant hazard due to its potential for spreading radioactive contamination over a wide area. Cleanup efforts typically focus on containing and disposing of the debris to minimize the risk to human health and the environment.
Actually this is false most of the Cold War era nuclear weapons have been destroyed.At the peak of the Cold War the U.S. had about 10,000 strategic and 20,000 tactical nuclear weapons and the USSR had about 10,000 strategic and 30,000 tactical nuclear weapons.Following the signing of START both sides agreed to destroy all tactical nuclear weapons and reduce strategic nuclear weapons slowly over a period of time.At this time both the U.S. and Russia have about 3,500 strategic nuclear weapons each and no tactical nuclear weapons (although some people say that Russia secretly maintains about 1,000 tactical nuclear weapons).So, from a peak of about 70,000 nuclear weapons during the Cold War to about 7,000 nuclear weapons now, only about 10% of the weapons then available still remain ready for use.
Nuclear weapons emit various types of radiation, including gamma radiation, neutron radiation, and thermal radiation. These forms of radiation can have harmful effects on living organisms and the environment.
Both Russia and the United States possess strong nuclear arsenals with similar destructive capabilities. The exact strength of each country's nuclear weapons is classified, but they both have the ability to cause immense damage and are considered two of the most powerful nuclear states in the world.
The force responsible for the release of energy in nuclear power plants and nuclear weapons is nuclear fission. This process involves splitting of atomic nuclei, which releases a significant amount of energy in the form of heat and radiation.
Synthetic elements are obtained: - in nuclear reactors - as a result (in debris) of nuclear weapons explosions - with the aid of particle accelerators

From 1945 until the late 1970s or early 1980s the United States always had the most nuclear weapons. After then the USSR/Russia has had the most nuclear weapons.
America has the most nuclear weapons

As the category for this question is "Nuclear weapons", I'm presuming it refers to nuclear arms.As of 2012, the three countries with the largest stockpiles of nuclear weapons are, in order from most to least:RussiaUnited StatesFrance
In the most basic sense, proliferation of nuclear weapons is the spread of nuclear weapons and weapons usable technology in the world. In a much broader sense, it refers to the acquiring of capability to produce nuclear weapons, or weapons-grade nuclear material (high-enriched uranium, plutonium) by states previously not possessing them.
The most powerful.

The country with the biggest stock of nuclear weapons, and hence, the biggest productor is the Russian Federation. They have over 12,000 nuclear warheads.
