The proliferation resistance is evaluated based on the plutonium inventory, fissile plutonium fraction, decay heat and spontaneous fission neutrons emission rate per unit weight of the recovered plutonium, 238 Pu/Pu ratio, and 232 U/ 233 U ratio. 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 2021-04-18 · Pu-238 exhibits high heat density and emits primarily alpha particles, which are easily shielded; this makes it safer to handle than most other radioactive materials. 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

Pu-238 emits alpha particles as it decays, which means it is a constant heat generator. However, the particles can be blocked by almost any barrier, meaning it cannot be used in nuclear reactions and is much less harmful than other isotopes. The half-life of Pu-238 is 87.7 years. Pu-238 is ideal for deep-space travel because of its long half-life of nearly 88 years, but it has been in short supply.

Pu-238 has a half-life of 87.7 years, making it a much longer-lasting source of energy than polonium-210, which was used in the 1959 RTG prototype and has a half-life of 138 days. Pu-238 exhibits high heat density and emits primarily alpha particles, which are easily shielded; this makes it safer to handle than most other radioactive materials.

Plutonium has five "common" isotopes, Pu-238, Pu-239, Pu-240, Pu-241, and Pu-242. All of the more common isotopes of plutonium are "fissionable"—which means the atom's nucleus can easily split apart if it is struck by a neutron. The various isotopes of plutonium have been used in a number of applications. Plutonium-238 (Pu-238).

Plutonium opstår når 238 U absorberer en af disse neutroner, hvorved 238 U bliver til 239 U, der betahenfalder til 239 Np, som igen betahenfalder til 239 Pu.

Plutonium-238 Isotopen 238 Pu är kortlivad med en halveringstid av 88 år. Genom den intensiva alfastrålningen blir ett stycke av denna isotop upphettat till vitglödning. The adopted value of the 238Pu spontaneous fission is 4.74(12)·1010 years where the uncertainty is the smallest experimental uncertainty. Table 2.
