| plutonium | <chemical> Plutonium. A naturally radioactive element of the actinide metals series. It has the atomic symbol pu, atomic number 94, and atomic weight 242. Plutonium is used as a nuclear fuel, to produce radioisotopes for research, in radionuclide batteries for pacemakers, and as the agent of fission in nuclear weapons. Chemical name: Plutonium (12 Dec 1998) |

Synonyms :
| plutonium |
a solid silvery grey radioactive transuranic element whose atoms can be split when bombarded with neutrons; found in minute quantities in uranium ores but is usually synthesized in nuclear reactors; 13 isotopes are known with the most important being plutonium 239

| plutonium |
a heavy, radioactive, man-made, metallic element (atomic number 94) used in the production of nuclear energy and the explosion of nuclear weapons; its most important isotope is fissile plutonium-239, produced by neutron irradiation of uranium-238.

| plutonium |
A radioactive metallic element chemically similar to uranium. PM-10/PM-2.5: PM 10 is measure of particles in the atmosphere with a diameter of less than ten or equal to a nominal 10 micrometers. PM-2.5 is a measure of smaller particles in the air. PM-10 has been the pollutant particulate level standard against which EPA has been measuring Clean Air Act compliance. On the basis of newer sceientific findings, the Agency is considering regulations that will make PM-2.5 the new "standard".
