CTBTO • The Comprehensive Nuclear-Test-Ban Treaty (CTBT) bans all nuclear explosions • The CTBT was negotiated in 1996 • 44 specific nuclear technology holder countries must sign and ratify the treaty before the CTBT can enter into force. • The Preparatory Commission for the CTBTO was founded in 1996 and it is based in Vienna. • Signs of nuclear explosions are monitored with the International Monitoring System (IMS). It will consist of 337 facilities worldwide, when completed. • Data from the IMS monitoring stations is sent to The International Data Centre (IDC) at the CTBTO's headquarters in Vienna.

Radionuclide laboratory FIL 07 • STUK hosts one of the CTBTO IMS radionuclide laboratories, FIL 07 • FIL 07 was certified in 19. 12. 2003 • Hosted by the Environmental Radiation Surveillance and Emergency Preparedness Department (VALO) of STUK • Most part of management, analysts and laboratory personnel from the Environmental surveillance and measurement laboratory (VAM) • Analysts and lab personnel also from other units/departments of STUK. SÄTEILYTURVAKESKUS • STRÅLSÄKERHETSCENTRALEN RADIATION AND NUCLEAR SAFETY AUTHORITY

FIL 07 Organizational details • The quality manager of the VALO department is also the head of FIL 07. The Head of FIL 07 formally approves the quality manuals and is responsible for providing needed resources to FIL 07. • The FIL 07 Official is responsible for maintaining the FIL 07 quality system and FIL 07 specific infrastructure, IMS sample analysis, daily operations and preparedness, periodic reporting and FIL 07 specific aspects of QA/QC program, maintaining relations to PTS and taking part into national CTBTO related work (WGB meetings, workshops, national meetings, etc. . ). • VAM laboratory is responsible for QA/QC program components common with the ISO/IEC-17025 requirements, counting rooms and spectrometer upkeep and providing analysts for FIL 07 SÄTEILYTURVAKESKUS • STRÅLSÄKERHETSCENTRALEN RADIATION AND NUCLEAR SAFETY AUTHORITY

STUK gamma laboratory facilities • Two low background counting rooms: • Construction from selected concrete and mortar with low abundance of natural radionuclides • Special air ventilation and continuous radon monitoring (radon levels ~3 Bq/m 3) • ≈ 15 HPGes in vertical cryostats (LN/electric) • Pb BG-shielding • ISO/IEC 17025 accreditation. • Currently one certified spectrometer for IMS sample analysis • Certification of a second spectrometer under way SÄTEILYTURVAKESKUS • STRÅLSÄKERHETSCENTRALEN RADIATION AND NUCLEAR SAFETY AUTHORITY

FIL 07 hardware and software • LN cooled Canberra BEGe-5030 spectrometer (48% rel. eff. ) • 13 cm lead shield • Ortec Dspec Pro • Unisampo acquisition software • Unisampo-Shaman analysis software • Linssi database • Physically separate LAN, firewalled access • Satellite connection based GCI link • Electronic Document Management System – SAHA SÄTEILYTURVAKESKUS • STRÅLSÄKERHETSCENTRALEN RADIATION AND NUCLEAR SAFETY AUTHORITY

FIL 07 software and database • Unisampo acquisition software (interfaces with the Ortec Dspec Pro MCA) • Unisampo-Shaman analysis software • Peak analysis in Unisampo, Shaman runs the nuclide identification engine • Linssi 1. 1 database, lab specific web interface and message management • • • Messages, calibration, sample, measurement and analysis data in the database Generation and management of messages between FIL 07 and IDC Automatic incoming and outgoing message processing and database input Automatic sample generation into database from PRESDN and LABSDN messages Sample information updated for lab-pressed samples Measurement and analysis data input (from Unisampo and Shaman ) Analysis reports output (PHD, RLR) Runs on a linux server Dedicated authentication server (digital signature to outgoing messages) Sample chain-of-custody records are updated in the Linssi database as the sample is processsed trough the various stages in the analysis chain SÄTEILYTURVAKESKUS • STRÅLSÄKERHETSCENTRALEN RADIATION AND NUCLEAR SAFETY AUTHORITY

Web interface • Web interface for generating messages and sample tracking SÄTEILYTURVAKESKUS • STRÅLSÄKERHETSCENTRALEN RADIATION AND NUCLEAR SAFETY AUTHORITY

FIL 07 sample preparation and storage • • Dedicated sample preparation and storage room for IMS samples Limited access Locked cabinet for IMS samples Separate facilities for high activity samples SÄTEILYTURVAKESKUS • STRÅLSÄKERHETSCENTRALEN RADIATION AND NUCLEAR SAFETY AUTHORITY

IMS sample types • IMS samples include three different types of filter samples RASA, Manual 50 and Cincerella. • Manual 50 samples are compressed to optimal geometry in the stations. No sample preparation needed in the lab. • Cinderella filters are measured in stacks. • RASA filters are delivered to the lab as whole filters and they are compressed in the lab.

Measurement and analysis chain • Sample related Linssi tables updated automatically from PRESDN and LABSDN messages (a new sample or existing sample data updated or amended) • Sample preparation for HPGe measurement • • • updating the sample data in the Linssi database via web interface measurement. Setup information Generation of null phd with calibration and sample data • Sample measured using Unisampo software (1 -7 d) • • sample data from the null phd to Unisampo when starting the measurement Spectrum is saved at regular intervals (as a phd file) • Manual analysis using Unisampo-Shaman • • • Phd file is manually read in Analysis results saved to Linssi (manual save) Automated pipeline is not in use • Report (PHD, RLR) generation from the Linssi web interface • Lab message pipeline autheticates and pushes the results into GCI • Results have to be reported in 15 days from sample arrival SÄTEILYTURVAKESKUS • STRÅLSÄKERHETSCENTRALEN RADIATION AND NUCLEAR SAFETY AUTHORITY
