In this study, the gamma emission tomography and the virtual point-detector method were combined to calculate the efficiency of the radionuclide inside the radioactive waste drum. Therefore, the radioactivity of the radionuclide inside the waste drum has been calculated. The results showed that the source location was determined by the gamma emission tomography for good results with the experimental value. The discrepancies between measured and true activity were smaller than 13% for the sand matrix.
