High heat density and low shielding requirements both make for a lighter device. Unlike Pu-239, Pu-238 is non-fissile, so it cannot be used in nuclear power plants or nuclear weapons. 238 Pu 87,7 år: α och SF: 5,593 234 U: 239 Pu 24 100 år: α och SF 5,245 235 U: 240 Pu 6 564 år α β och SF 5,256 0,005 236 U 240 Am: 241 Pu 14,4 år α β och SF 5,14 0,021 237 U 241 Am: 242 Pu 376 300 år α och SF 4,984 238 U: 244 Pu 80,8·10 6 år α och SF 4,666 240 U ENDF/B-IV PU-238 resonance total cross section 10-6 10-5 Energy (MeV) 101 102 103 Cross section (barns) total (Pu-238) Supply Program Alternatives Analysis Team related to the current plan for production of Pu-238 in the United States.

By these estimates, the mass plutonium needed for the average nuclear bomb, or about 6 kg goes for about thirty-one million dollars. Plutonium-238 is a radioactive isotope of plutonium that has a half-life of 87.7 years. Plutonium-238 is a very powerful alpha emitter; as alpha particles are easily blocked, this makes the plutonium-238 isotope suitable for usage in radioisotope thermoelectric generators and radioisotope heater units.
