OBJECTIVES
Special Studies provide in-depth, technical reviews by expert analysis of data from the International Monitoring System (IMS) to improve the estimated values for the standard signal and event parameters resulting in an Updated Radionuclide Report (URR). The purpose of the Expert Technical Analysis (ETA) of IMS data and other relevant data provided by the requesting State Party is to assist the State Party concerned in identifying the source of specific events. The output is the State Requested Methods Report (SRMR).


URR and SRMR need to be seen in the context of the standard products they are building on; specifically, the Standard Screened Radionuclide Event Bulletin (SSREB). Beyond its current implementation, it may contain, among others, the use of atmospheric transport modelling results to combine the field of regard information from all radionuclide samples sharing a possible common source region related to a single event. If available, information derived from isotopic ratios is included and may be used to confine the field of regard.


The National Screened Radionuclide Event Bulletin (NSREB) was introduced and needs to be developed.

The objectives of this technical expert meeting are:

  • Discuss advances of existing methods and procedures for Special Studies and ETA as well as introduce new approaches;

    - Discussion of potential radionuclide and ATM methods for Special Studies and ETA;
    - Discuss methods to determine which samples are related to the same event;
    - ATM methods to locate the source for single or multiple samples;
    - Characterization of the atmospheric isotope background based on known man-made sources;
  • Discuss the possible content of the URR, SSREB, NSREB, and SRMR;
  • Explore the potential use of various non-IMS data for SRMR;
  • Fusion between radionuclide and SHI events;
  • Advance common understanding of procedures and methods for the SSREB, URR, SRMR and NDC responsibilities.


Meeting participants are welcome to contribute to the technical meeting by making a brief presentation related to one of the Agenda topics.


AGENDA
To be determined. The focus will be on Special Studies and Expert Technical Analysis - developing and reviewing procedures, methods, guidelines on the use of data, and content of URR, SSREB, NSREB and SRMR.

PARTICIPANTS PROFILE
Experts from NDCs and research establishments that are involved in applying and developing radionuclide and ATM methods that may be suitable for Special Studies and Expert Technical Analysis.
