Simulated and real experimental data are used to investigate the use of: (1) active computed tomography (ACT) to obtain images of attenuated gamma-rays from a waste-canister interior; (2) passive computed tomography (PCT) to locate and determine the radioisotopic sources present; and (3) ACT data to correct PCT data so that accurate radioisotopic source activities can be determined. Active and passive computed tomography (CT) techniques were used to analyze a small container of mock-waste. Both simulated and experimental results reveal that the ACT scans properly map the canister`s attenuating matrix and coupled with PCT scans, can yield quantitative source activities.
