plutonium

 (Pu) [ploo-to´ne-um]
a chemical element, atomic number 94, atomic weight 242. (See Appendix 6.)

plu·to·ni·um (Pu),

(plū-tō'nē-ŭm),
A transuranium artificial radioactive element, atomic no. 94, atomic wt. 244.064. The best-known α-emitting isotope is 239Pu (half-life 24,110 years) which, like 235U, is fissionable and can be used in atomic bombs and nuclear power plants; 238Pu (half-life 87.74 years) is used as an energy source in pacemakers. Pu ions are bone-seekers; ingestion is a radiation hazard, as with radium and radiostrontium.

plutonium

/plu·to·ni·um/ (Pu) (ploo-to´ne-um) chemical element, at. no. 94.

plutonium (Pu)

[plo̅o̅tō′nē·əm]
Etymology: planet Pluto
a synthetic transuranic metallic element. Its atomic number is 94; the atomic mass of its longest-lived isotope is 242. A highly toxic heavy metal, plutonium is used in nuclear power plants, and was used in the assembly of early nuclear weapons.

plutonium

A highly poisonous, radioactive metallic element produced from uranium in atomic breeder reactors and used as a fissile element in nuclear weapons. Plutonium concentrates in the bones where it remains for many years.
