Evaluation of Received Dose Distribution of 18F Production with Iranian Sun Plasma Focus Device (IS)

Abstract

The best way to use radioisotopes with short half-lives is to produce them at the injection site.

 Iranian Sun Plasma focus Device is a nuclear fusion reactor that is convenient for radioisotopes produced with short half-lives for medical use. Here have been used same geometries with IS device. In this Theoretical study, H₂O and O₂ targets were used for ¹⁸F production. This study compared the dose and energy distribution, in water and G4_MUSCLESKELETAL_ICRP phantoms at different distances and directions from the proton source. The beam-target mechanism was simulated by the GEANT4.10.7 tool and used the G4EmStandard Physics_option3 physic model. To provide a more accurate simulation of particle ranges in physics constructors for the 18F production with the 10⁷ protons in each shake with 5.02 MeV energy, of course, to get this energy, there is a need to review the structure of this device. Dose distributions in the vertical direction are half of Dose distributions in the same direction of the source beam. The dose profile for G4_MUSCLESKELETAL_ICRP and H2O phantoms match 99% obtained by gamma index matching.
