Abstract
At SPERA 2010, the results of a study on the low-level building materials including a special concrete mix for the development of a basement gamma spectrometry laboratory at Ansto were presented. Since the completion of the Environmental Radioactivity Measurement Centre using these ideal materials at ANSTO in early 2012, there has been a reduction of approximately 30% in the background counts. In this presentation, the success in achieving the reductions will be compared to the previous gamma laboratory setting. This will reflected particularly through the radionuclides tested using an IAEA Quality Assurance method, as well as the counts per second across a broad energy range for the detectors in the laboratory.
