title: Trace analysis of aerosol bound particulates and noble gases at the BfS in Germany.
abstract: The Federal Office for Radiation Protection (BfS) performs trace analysis measurements in both the frameworks of the German Integrated Measuring and Information system as well as of the International Monitoring System for verification of the Comprehensive Nuclear-Test-Ban Treaty. Therefore, different kinds of measurements of aerosol bound radionuclides as well as of radioactive noble gases in the atmosphere are performed. BfS as coordinating laboratory for trace analysis is responsible for the quality control. A quality assurance programme was set up with German institutions and expanded to European laboratories. The existing quality assurance programme of the Comprehensive Nuclear-Test-Ban Treaty Organisation for measurements of aerosol bound radionuclides will be extended for noble gas measurements. Applied methods, achieved measurement results and the different kinds of quality assurance are presented and discussed.
