Chelation Model Validation: Modeling of a Plutonium-238 Inhalation Incident Treated with DTPA at Los Alamos National Laboratory. [PDF]
Health Phys, 2023 Accidental inhalation of plutonium at the workplace is a non-negligible risk, even when rigorous safety standards are in place. The intake and retention of plutonium in the human body may be a source of concern.

Advection–Dispersion Behavior for Simulation of H-3 and Pu-238 Transport in Undisturbed Argillaceous Shale of a Near-Surface Repository [PDF]
Toxics, 2023 In this study, a column experiment was employed to evaluate the nuclide migration behavior in the surrounding rock medium of a near-surface disposal site in China and to investigate the advection–dispersion behavior of tritium (H-3) and plutonium-238 (Pu-

Optimal Neutron Spectrum Database for In‐reactor 238Pu Production [PDF]
Advanced SciencePlutonium‐238 (238Pu) is a scarce heat‐source radioisotope used in nuclear batteries, which is produced by in‐reactor irradiation of Americium‐241 (241Am) or Neptunium‐237 (237Np).

Plutonium 238/239 Decorporation Model [PDF]
, 2014 Abstract : A treatment model for Pu-238/239 internal contamination by DTPA was developed to evaluate efficacy of various treatment regimens. The model estimates Pu deposition, absorption, distribution, retention, excretion, and response to DTPA after an inhalation exposure.

ASAIO Journal, 2012 Ventricular assist devices emerged as a widely used modality for treatment of end-stage heart failure; however, despite significant advances, external energy supply remains a problem contributing to significant patient morbidity and potential mortality. One potential solution is using the nuclear radioisotope Plutonium-238 as a power source.

Inertial fusion-assisted production of Plutonium 238 [PDF]
Laser and Particle Beams, 2017 AbstractIt is proposed to assist and substantially increase the production of Plutonium 238 by inertial fusion inside a pipe made of stainless steel passing through the core of a conventional nuclear fission reactor, by injecting a stream of pellets of Neptunium 237 encapsulated liquid deuterium–tritium (DT) under high pressure. Then, if from both ends
