PLUTONİUM
It is symbolized by "Pu" and is included in the actanites group of the 7th period of the periodic table. Its melting point was measured as 640 ° C (1184 ° F or 913 K) and its boiling point was measured as 3228 ° C (5842 ° F or 3501 K). It is solid under room conditions. It darkens when it comes into contact with the air and has a silvery color. All of its isotopes are radioactive. The most well-known isotope, plutonium-239, has a longer half-life than others. Plutonium was discovered at the University of California at Berkley in 1941 by scientists Joseph W. Kennedy, Glenn T. Seaborg, Edward M. McMillan, and Arthur C. Wohl.
Usually not found in nature, but small amounts of plutonium can be found in uranium ores. Plutonium is a byproduct of the nuclear power industry. About 20 tons of plutonium are produced each year, according to the Los Alamos National Laboratory. Atmospheric weapons tests conducted in the 1950s and 1960s dropped tons of plutonium into the Earth's atmosphere, according to the World Nuclear Association.
Although it is an element not used much commercially, one third of the materials used in nuclear energy is plutonium element. It is touted in the media as "the most toxic element known to man," but scientists deny it. Since plutonium does not contain gamma radiation, health problems are unlikely when working with plutonium unless it is inhaled or ingested in some way. In addition, no death from plutonium has been recorded since 2003.
Interesting information:
Plutonium is named after the planet Pluto. This is not because, as you think, this element is abundant in Pluto. The main reason is this: uranium, named after the planet Uranus, and the field of the planet Neptune comes after neptunium.
