Dosimetric evaluation of extremities in 18F-FDG PET/CT procedure using Monte Carlo Geant4 code

Abstract

For the dosimetric evaluation of extremities and crystalline of workers inserted in Positron Emission Tomography procedures using the 18F-FDG radiopharmaceutical, a geometric phantom of the forearm and hand with the geometric phantom ADAM was implemented in Monte Carlo Geant4 code. Equivalent Dose values were obtained in 45 different points - between dominant, non-dominant and crystalline hands - for radiopharmaceutical administration procedure, with the use of injection syringe shielding. The data obtained through the simulation were analyzed according to dose limits established by the CNEN standard NN-3.01 of 2014.
