He plutonium is a radioactive substance characterized by its high level of toxicity . The term comes from the English word plutonium and its name is linked to the arrangement of the chemical elements in the periodic table: the plutonium follow the uranium and at neptunium , like Pluto to the planets Uranus and Neptune .
Atomic number 94 , it is a metallic chemical element that belongs to all the actinides . His symbol is Pu And presents isotopes high stability, which are used as a gas and how explosives .
In the decade of 1930 , the Italian chemist Enrico Fermi he thought he discovered a new element he baptized as hesperium . However, it was actually a combination of krypton , barium and other components. From the findings of Fermi progress was made in the investigation and finally the production and isolation of plutonium was first achieved in 1940 thanks to a scientific team of the University of California, Berkeley (U.S ).
The most stable isotopes of plutonium are the plutonium-239 (which takes 24,110 years to disintegrate) and the plutonium-242 (whose disintegration time reaches 373,300 years). Although considered as the gas Most dangerous nuclear, plutonium is used in different ways.
The manufacture of atomic bombs , the development of thermoelectric plants and the production of pacemaker These are some of the uses that are given to plutonium. It is important to keep in mind, however, that plutonium is very harmful to all of the living beings , so your handling must be extremely careful.
