1. AvaliaÃÃo da eficÃcia do avental equivalente a 0,5 mm de chumbo em tomografia por emissÃo de PÃsitrons atravÃs de simulaÃÃes Monte Carlo / Evaluation of the effectiveness of 0.5 mm lead equivalent apron in positron emission tomography by Monte Carlo simulation
In Positron Emission Tomography (PET), medical staff is exposed to 511 keV photons, which is a result of the positron-electron annihilation process. This energy is about four times the 140 keV commonly found in studies based on Single Photon Emission Computed Tomography (SPECT). Despite these different energy levels, 0.5 mm lead equivalent aprons have being
