  • To revisit current categorization schemes;
  • To share experience on tested categorization schemes; and
  • To present alternative and additional approaches.



  • Discussion of the definition of radionuclide event;
  • Sharing operational experiences, statistics and lessons learned on tested categorization schemes and different types of filters;
  • Consideration of the need for further scientific studies on alternative categorization methods;
  • Consideration of the use of laboratories in confirming the character of the event based on radionuclide event screening categories;
  • Consideration of the use of atmospheric transport modelling in combining different noble gas and particulate detections together;
  • Consideration of simultaneous categorization of the noble gas and particulate systems co-locating in the same station.

CTBT Science and Technology 2013 Conference

  • The Earth as a complex system
  • Events and their characterization
  • Advances in sensors, networks and processing.
