Characterization and Screening of Radioactive Waste Using Canberra’s ISOCS System
Posted on July 1st, 2015

Almost all Radioactive Material Licensees, ranging from nuclear power plants to small businesses, deal with the problem of radioactive waste. Quantification and identification of waste for disposal can be challenging. Often times licensees find themselves struggling with legacy waste where the only information available is in the form of word of mouth for the isotopic mix and activity.

Nasser Rashidifard of RSCS recently presented at the 2015 Canberra User's Group Meeting on the use of the Canberra In-Situ Object Counting System (ISOCS) for screening and quantification of gamma emitting isotopes to support large and small scale waste disposal activities. The presentation provides examples of how the high purity germanium system paired with the calibration software allows for accurate modeling of complex items that would prove difficult using traditional methods.  This waste characterization method can significantly impact the percentage of materials that can be free released or recycled. One case study offered demonstrates how the utilization of this equipment on a large scale project provided cost savings upwards of 95% for disposal budget when used as a screening tool to disposition bulk and large items. 

The presentation also explores the added safety benefits for personnel when materials are identified and quantified in situations where potential chemical and biological hazards are present.
