2nd Expert Meeting on Special Studies and ETA with RN and ATM Methods

  Vienna, VIC
  03 Oct 2019 - 04 Oct 2019

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 to identify 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 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 objectives of this technical expert meeting are:

  • Review methods that may be suited for Special Studies and ETA;
  • Discuss the possible content of the URR and SRMR;
  • Explore the potential use of various non-IMS data for SRMR;
  • Advance common understanding of methods to be developed for the SSREB, URR, SRMR and NDC responsibilities.

    Meeting participants are welcome to contribute to the technical meeting by making a 15 minute presentation related to one of the Agenda topics.
