Most of the alpha decay populates the U-234 ground state (71.04 %) and the U-234 ﬁrst excited level with energy of 43.50 keV (28.85 %). Branching of Pu-238 decay by spontaneous ﬁssion is 1.85 (5)E-7 %. Le plutonium 238 se d´esint`egre par ´emission alpha vers les niveaux fondamental (71,04 %) et excit´e de 43,5 The high decay heat of plutonium-238 (0.56 W/g) enables its use as an electricity source in the RTGs of spacecraft, satellites and navigation beacons. Its intense alpha decay process with negligible gamma radiation calls for minimal shielding. Plutonium-238 undergoes alpha decay as shown: 238 Pu + 4x + 4He Enter the appropriate values for A and Z and the chemical symbol for X. Plutonium-238 has a half-life of 87.74 years and emits alpha particles.

Uranium-238 decays by alpha emission into thorium-234, which itself decays by sustain a chain reaction, but it can be converted to plutonium-239, which can.

[Use 238 for the atomic mass of Pu-238] Wolfram|Alpha brings expert-level knowledge and capabilities to the broadest possible range of people—spanning all professions and education levels. 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). 2019-12-14 238 Pu : Half-life: Boson, 94p 144n: 87.83612379503 y: Spin 0 Parity 1: Hide Decay Modes: Probability: Mode: Decay Energy: Daughter: 100%: α: 5.5932MeV: 234 U: 1.9 and a re-measurement of the alpha decay data of 240Pu Deliverables : a new set of alpha-particle emission probabilities, also for the less intense peaks.
