The protocol to the Comprehensive Nuclear-Test-Ban Treaty CTBT provides for the designation of a number of radionuclide laboratories to support the radionuclide monitoring network of the International Monitoring System IMS. These laboratories, after being certified and when requested by the Technical Secretariat, are to provide additional analytical services, such as confirmatory gamma-ray spectrometry, quality control and intra laboratory exercises. The Environmental Measurements Laboratory EML has been designated as the U. S. CTBT Radionuclide Laboratory. EML is developing a separate secure facility for performing the required CTBT analyses and is currently set up for gamma-ray spectrometry with two, 120, HPGe detectors. The laboratory will undergo a preliminary certification exercise with the CTBT Technical Secretariat which will included verification of the laboratorys quality assurance plan as well as its current analytical capability. EMLs CTBT laboratory is in the process of expanding its radiochemistry and counting capabilities to include both alpha and beta emitting radionuclides. This paper presents EMLs continuing development of a radionuclide laboratory to corroborate the results of the routine analysis of a sample from an IMS radionuclide station, achieve a greater sensitivity for fission product analysis than can be achieved at the radionuclide stations and clarify the presence or otherwise of fission products in the case of a suspect or irregular analytical result from a particular radionuclide station.
