Description

The Mirion WM2211 Segmented Assay System is designed to perform accurate quantitative assays on gamma emitting nuclides found in fission product, activation product, and Transuranic (TRU) waste. With the optional ASTM algorithms it is also designed for use in safeguards applications. The system provides very accurate assays through the use of a collimated high purity germanium detector. The container is divided into a number of vertical segments and the activity is quantified in each vertical segment using matrix correction techniques which calculate the average matrix density for each segment. The system is designed to assay drums with volumes up to 320 L (85 gal) and weights up to 900 kg (2000 lb) in its standard configuration. Optional configurations have been provided for larger or heavier containers.

The standard system is designed to assay radionuclides such as 60Co or 137Cs with drum activities ranging from approximately 100 nCi up to approximately 20 mCi. For transuranic waste the system is optimized for assaying drums containing 0.1 gram up to 1000 grams of 235U or 239Pu. Detector size and collimation can be used to modify the dynamic range of the system.
