Description
The disposal of radioactive wastes into a repository requires a detailed specification of the radioisotopic inventory of the waste containers. This paper describes an advanced tomography assay system capable of identifying and localizing all detectable radioactive nuclides contained in Low-Level-Waste-drums (LLW) and quantitatively determining their activities. The assay system uses a combined transmission and emission tomography technique. Whereas transmission computerized tomography is applied to examine the contents of the drums in respect of inhomogeneous fillings (density distribution), emission computerized tomography is used to inspect the radionuclide inventory (activity distribution). The paper describes in detail the tomography assay system including its major components. Measurements on LLW-drums as well as reconstructed images of the density and activity distribution of the drums' contents are a special subject of the paper
