Plutonium's most stable isotope, plutonium-244, can last a long time. It has a half-life of about 82 million years and decays into uranium-240 through alpha decay, according to theJefferson Lab. Plutonium was named after the planet, Pluto. This is because it came after Uranium, which was...
Plutonium-238 pellets with a half-life of 87.7 years is an effective source of electricity for radioactive thermoelectric generators used in space probes [2]. It has also been used to power some cardiac pacemakers [8]. Pu-239 is used in several nuclear power plant reactors and weapons as ...
Isotopes:There are 15 known isotopes of plutonium. The isotope of greatest importance is Pu-239, with a half-life of 24,360 years. Properties:Plutonium has a specific gravity of 19.84 (a modification) at 25°C, melting point of 641°C, boiling point of 3232°C, with a valence of 3, ...

(the half-life of plutonium-238 is 87.7 years). The power produced from plutonium-238alpha decay(approximately 0.5 watt per gram) has been used to providespacecraftelectrical power (radioisotopethermoelectric generators[RTGs]) and to provide heat for batteries in spacecraft, such as in the...
The decay product of 129 I is conspicuously absent in lunar samples and this may be attributed to the facts that (a) the half-life of 129 I is much shorter than that of 244 Pu, and (b) the separation of xenon from plutonium may take place easily, since the former is a gaseous ...
Plutonium-238 (half-life 87.7 years) was produced by deuteron bombardment of uranium-238 in the 60-inch cyclotron in Berkeley, California. The Berkeley team madeneptunium-238(half-life 2.1 days) which decayed to plutonium-238:(1) 238U +2H ⇒238Np +2n ...
