CLEA

Waste Measurement System

Radioactive waste with activity or specific activity below the clearance level can be released from regulatory control. The fully automated high-resolution low-level gamma spectroscopy CLEA checks these clearance levels and warns when levels are exceeded.

Description

Radioactive waste with activity or specific activity below the clearance level can be released from regulatory control. The fully automated high-resolution low-level gamma spectroscopy CLEA checks these clearance levels and warns when levels are exceeded.

The CLEA combines the best resolution HPGe detector technology with ultra-low microphonic electrical cooling combined with a Multi Channel Analyzer with Digital Signal Processing. The lead shielded system has a balance to obtain results in Bq per gram. Rotation of the drum is applied during measurements to compensate for in-homogeneously distribution of the radio active material in the drum. Each waste drum presented for measuring is identified by a unique barcode number, the results are stored in a database. The CLEA is a member of the Waste Watchers (W2) Family.
