What is the half life of plutonium 239 which were found as far away as Sweden?
Other radionuclides will stay in the region almost forever. The half-life of plutonium-239, the traces of which were found as far away as Sweden, is 24,000 years.
What did South Africa do with their nukes?
South Africa ended its nuclear weapons programme in 1989. All the bombs (six constructed and one under construction) were dismantled and South Africa acceded to the Treaty on the Non-Proliferation of Nuclear Weapons when South African Ambassador to the United States Harry Schwarz acceded to the treaty in 1991.
Was plutonium used in war?
The process was originally developed in the United States as part of its nuclear weapons program during World War II, and some of the recovered plutonium was used in the bomb detonated over Nagasaki, Japan on August 9, 1945.
What are the major impacts caused by a nuclear detonation?
The Effects of Nuclear Weapons Blast, thermal radiation, and prompt ionizing radiation cause significant destruction within seconds or minutes of a nuclear detonation. The delayed effects, such as radioactive fallout and other environmental effects, inflict damage over an extended period ranging from hours to years.
What is an interesting fact about plutonium?
It has a half-life of about 82 million years and decays into uranium-240 through alpha decay, according to the Jefferson Lab. Plutonium was named after the planet, Pluto. This is because it came after Uranium, which was named after the planet Uranus, and neptunium, which was named after the planet Neptune.
How much plutonium is left in the world?
The global stockpile of separated plutonium was about 545 tons.
Does Canada have nukes?
Canada has not officially maintained and possessed weapons of mass destruction since 1984 and, as of 1998, has signed treaties repudiating possession of them. Canada ratified the Geneva Protocol in 1930 and the Nuclear Non-proliferation Treaty in 1970.
What is the history of plutonium?
‘ A radioactive, silvery metal. Plutonium was used in several of the first atomic bombs, and is still used in nuclear weapons….

Why is plutonium important?
plutonium (Pu), radioactive chemical element of the actinoid series of the periodic table, atomic number 94. It is the most important transuranium element because of its use as fuel in certain types of nuclear reactors and as an ingredient in nuclear weapons.
How nuclear bombs affect the environment?
A detonated nuclear bomb produces a fireball, shockwaves and intense radiation. A mushroom cloud forms from vaporized debris and disperses radioactive particles that fall to earth contaminating air, soil, water and the food supply. When carried by wind currents, fallout can cause far-reaching environmental damage.
How does nuclear power affect the environment and human health?
Nuclear energy produces radioactive waste A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years.
