ABSTRACT
To estimate the finger dose absorbed by $^{99m}Tc$ injection, simulations are carried out to calculate the dose equivalent of each finger per second with radioactivity of 370 MBq, based on the GEANT4 simulator. For the $^{99m}Tc$ source of the volume of 0.4mL and the radioactivity of 370 MBq, we obtained the dose equivalent of the right thumb ($0.29;{mu}Sv{cdot}sec^{-1}$), the right index finger ($1.19;{mu}Sv{cdot}sec^{-1}$), the right middle finger ($1.07;{mu}Sv{cdot}sec^{-1}$), the left thumb ($4.36;{mu}Sv{cdot}sec^{-1}$), and the left index finger ($3.37;{mu}Sv{cdot}sec^{-1}$), respectively. This simulation results may serve as a useful data in the prediction of finger dose absorbed by $^{99m}Tc$ injection.
