title: A ultra low level laboratory for nuclear test ban measurements.
abstract: The radionuclide laboratory at the Austrian Research Centers Seibersdorf (ATL03) was installed to support the international monitoring system for verification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT and Text of the establishment of a Preparatory Commission for the Comprehensive Test-Ban-Treaty Organization, 1996). Therefore, the background of a high-purity germanium detection system has been reduced by developing a high sophisticated active and passive detector shielding. The entire system is encapsulated in an iron-castle and placed into a fall-out shelter. The final count rate, achieved over the energy interval from 40 to 2700 keV, amounts to 0.18 counts s(-1) kg(-1) (Ge).
