    • 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 the content of the radionuclide (URR, SSREB, NSREB) and waveform products (UEB, SSEB, and the ETA-SHI software suite) as well as the shared product SRMR.

    Additional specific objectives for the Expert Meeting on SS and ETA with Waveform Methods:

    • Advancing and reviewing the ETA-SHI software suite;
    • Develop or refine the possible content of the UEB, SSEB, NSEB, and SRMR.

    Additional specific objectives for the Expert Meeting on SS and ETA with Radionuclides (RN) and Atmospheric Transport Model (ATM) Methods:

    • Discuss ATM methods to locate the source region for single or multiple samples;
    • Characterise the atmospheric isotope background based on known man-made sources;
    • Advancing and reviewing the ETA-RN software suite
    • Develop or refine the possible content of the URR, SSREB, NSREB, and SRMR.

    Meeting participants are welcome to contribute to the Technical Meetings by making a brief presentation related to one of the objective’s topics in their related field.
