Longevity of Plutonium 238 Heat Sources
MRS Proceedings, 2012 ABSTRACTPlutonium oxide heat sources are used to power space missions. The heat produced by alpha decay of the 238 isotope of Pu is converted to electricity in a thermopile, providing electricity during a substantial fraction of the 88 year half-life of the isotope.

Chelation Modeling of a Plutonium-238 Inhalation Incident Treated with Delayed DTPA
Radiation Research, 2023 This work describes an analysis, using a previously established chelation model, of the bioassay data collected from a worker who received delayed chelation therapy following a plutonium-238 inhalation. The details of the case have already been described
