Abstract:
In the characterization of the radioactive waste containers, a reliable non-destructive method is high-resolution gamma spectrometry. However, the non-homogenous composition of the radioactive waste inside the drum makes the quantitative characterization of the radioactive waste drum a difficult task. The efficiency calibration procedure is difficult and dependent on different parameters such as: experimental set-up, the sources distribution inside the drum etc. An experimental calibration of the measurement system is difficult and expensive and especially cannot cover all the cases of interest . We present experimental studies complemented with Monte Carlo calculations performed for two different measurement geometries.
