Plutonium-238 Production and Usage Neutron capture in the 237Np nucleus produces 238Np, which beta-decays with a half-life of 2.12 days into 238Pu. 238Pu, in the form of PuO 2

Isotopic signatures of environmental plutonium are generally used to assess the origin of the material. While decay counting is restricted to 238 Pu, 239 + 240 Pu, and 241 Pu, all mass spectrometric methods can in principle detect the isotopes 239 Pu (T 1/2 = 24.1 ka), 240 Pu (6.65 ka), 241 Pu (14.4 a), 242 Pu (373 ka), and 244 Pu (80.8 Ma). 2015-07-23 The low-temperature heat capacity of (U 1−y Th y)O 2 and 238 Pu-doped UO 2 samples were determined using hybrid adiabatic relaxation calorimetry.

Kids learn about the element plutonium and its chemistry including atomic weight , Phase at Room Temperature: Solid; Density: 19.816 grams per cm cubed The main source of plutonium is from the use of uranium-238 in nuclear reactors

369-375. ASME. 238 Pu, 240 Pu, and 242 Pu have high spontaneous fission rate which can significantly reduce a weapon's yield; 238 Pu also has a large decay heat per unit weight that further complicates the design of an explosive device (Pellaud, 2002; Xu et al., 2005). A Pu-238 fuel pellet in its protective iridium cladding. Image Credit: Dept. of Energy The enhanced GPHS modules used in the latest generation of radioisotope power systems incorporate additional rugged, safety-tested features that build upon those used in earlier generations.

238 Pu makes up only one or two percent, but it may be responsible for much of the short-term decay heat because of its short half-life relative to other plutonium isotopes. Reactor-grade plutonium is not useful for producing 238 Pu for RTGs because difficult isotopic separation would be needed.
