Plutonium is a radioactivemetallicman made chemical element. In the periodic table it has the symbol Pu and the atomic number Its atomic weight is Plutonium was discovered in by Dr.
Seaborg and others working at the University of California, Berkeley ; the discovery was kept secret. It was named after the planet Plutohaving been discovered directly after Neptunium.
Pluto is the next planet out after Neptune. The most important isotope of plutonium is Pu, with a half-life of 24, years.
Because of its low half-life, there are only extremely tiny trace amounts of plutonium naturally. Plutonium is the key fissile component in modern nuclear weaponsand it could also be used to manufacture radiological weapons or as a not particularly deadly poison. Large stockpiles of plutonium were accumulated by both NATO and the Warsaw Pactwhich since the end of the cold war have become a focus of nuclear proliferation concerns.
Inthe United States Department of Energy took possession of 34 metric tons of excess weapons grade plutonium stockpiles from the United States Department of Defenseand as of early was considering converting several nuclear power plants in the US from enriched uranium fuel[?
Toxicity Plutonium is sometimes referred in media reports to as the most toxic substance known to man, although there is general agreement among experts in the field that this is overstated.
As ofthere has yet to be a single human death officially attributed to plutonium exposure, naturally-occurring radium is about times more radiotoxic than plutonium, and some organic toxins like Botulism toxin are billions of times more toxic than plutonium.
The chemical and radiological toxicity of plutonium should be distinguished from the danger of plutonium. Many, both in the anti-nuclear movement[? Possibly it is confusing these two issues that has led to sensational exaggerations[? A paper by Bernard L. In spite of the facts we have cited here, facts well known in the scientific community, the myth of Pu toxicity lingers on.
It is an alpha emitter, and this radiation does not penetrate the skin. The danger with all alpha emitters is rather if they are inhaled or otherwise ingested. Extremely small particles of plutonium on the order of micrograms can cause lung cancer if inhaled into the lungs.
Slightly larger amounts will cause acute radiation poisoning and death if ingested or inhaled.1 The real meaning of the words: a pedantic glossary of British nuclear weapons Introduction This glossary is intended as an aid for researchers, presenting the most accurate.
Little Boy. The design of Little Boy was completely different from Gadget/Fat Man. It used the gun assembly method that had originally been proposed for the plutonium bomb.

Plutonium is a silvery metal that turns yellow when exposed to air. It is warm to the touch due to the releasing radioactive energy from it.
