Souza-Santos Biología 18F FDG Geant4 geometric phantom Tomography of Positrons Emission A stylized phantom of forearm and hand was developed to assess extremities doses of workers in Positron Emission Tomography practices. This hand phantom was then coupled to a whole body ADAM phantom in order to evaluate eye lens doses as well. A case study, using 18F-FDG as the radiopharmaceutical, was simulated with the Geant4 Monte Carlo toolkit. Equivalent Dose values were obtained in 45 different points - in dominant and non-dominant hands and eye lens - for radiopharmaceutical administration procedure, with the use of injection syringe shielding. According to the data obtained, it can be observed that the most exposed points tend to be the index finger tips and the middle fingers for the dominant hand and the index finger for the nondominant hand, the highest dose reaching 23 times higher than the pulse dose. Both the dose estimates for extremities and eye lenses remain below the limit established by the CNEN standard NN-3.01 of 2014. From the obtained data, we can conclude that a good alternative for monitoring of eye lens is done positioning the dosimeter near the temples. For extremities it is recommended to use dosimetric rings at the base of the most exposed finger. 2019 artículo científico 2319-0612 https://www.redalyc.org/articulo.oa?id=722280901007 en http://www.redalyc.org/revista.oa?id=7222 Brazilian Journal of Radiation Sciences application/pdf Sociedade Brasileira de Proteção Radiológica - SBPR Brazilian Journal of Radiation Sciences (Brasil) Num.3B Vol.7 |
