The main present use is in space research, and ∼ 30 kW th power sources have been launched into space, 238 Pu has been used in heart pacemakers and is still a candidate as a power source for completely artificial hearts. Production of 238 Pu requires the isolation of 237 Np, which is then irradiated and reprocessed to produce pure 238 Pu.

Here you may find Pu! But this element-238 doesn't stink--it powers pacemakers Jeopardy Answer

Avril 1970, le pacemaker atomique (Laurens-Alcatel model 9000) est implanté à l'hôpital Broussais. Notre Commissariat à l'énergie atomique (CEA) eut à un moment un éclair de génie: doter le stimulateur cardiaque d'un générateur au plutonium 238. Plutonium (Pu) is a silvery-white metal. Plutonium-238 is a radioactive isotope of Pu, with special characteristics that make it extremely useful, particularly for space exploration. Chemical Structure.

Printable Version. Plutonium has five "common" isotopes, Pu-238, Pu-239, Pu-240, Pu-241, and Pu-242.

Disposal of Am-241 and Pu-238 Sources Los Alamos National Laboratory’s Off-Site Source Recovery Project ATTENTION: RADIATION SAFETY OFFICER The Los Alamos National Laboratory’s Off-Site Source Recovery Project (ORS) is a program to pick up and store unwanted or obsolete Am-241 or Pu-238 sealed sources. The contractor for this project has Critical masses were calculated for 238 Pu metal and oxide (bare, water reflected, 304 stainless steel reflected, and carbon steel reflected). The subcritical limit was calculated for isotopic mixtures of 238 Pu and 239 Pu oxide, dry or optimally moderated with water. The H/ 238 Pu ratio for which K inf = 1.0 and K inf for 238 Pu * Nuclear fuel for nuclear power reactors (Pu-239 and Pu-241 are fissile isotopes) * Nuclear weapons * Power and thermal sources - Pu-238 (for pacemakers, spacecrafts, etc.) * Neutron source, as Pu-Be Fact sheet: What is Pu-238?

238. This isotope, not to be confused withits neighbour plutonium-239 (used in nuclear weapons and powver stations), emits alpha-particles and has a half-life

Plutonium-238 is a special material that emits steady heat due to its natural radioactive decay. Several unique features of plutonium-238 have made it the material of choice to help produce electrical power for more than two-dozen U.S. space missions that have been enabled by radioisotope power systems (RPS).
