The Workshop on the Signatures of Man-Made Isotope Production (WOSMIP VI) brings together experts from the Treaty monitoring and isotope production communities to understand the effects of emissions of CTBT relevant radionuclides from nuclear facilities on the global radionuclide background and to explore means of enhancing the calibration and performance of Treaty verification systems without impacting the peaceful use of nuclear technology. Of interest are all man-made sources of these radioisotopes in the environment (nuclear power plants, research reactors, production, handling and use of medical isotopes, industrial isotopes, etc.) that may be observed by the radionuclide sensors of the International Monitoring System (IMS) or during On-site Inspection. The main objective of the workshop is to facilitate methods for characterizing radioxenon detection in the IMS based on thorough understanding of the radioxenon background in the atmosphere, taking account of all known sources and regional variations. 


  • Introductory session - goals of the work, description of the problem, review of pat activities;

  • Characterization of the atmospheric isotope background based on known man-made sources, including controlled source experiments;
    - Atmospheric transport modelling challenge.

  • Detection of emissions or events or effluents (includes remote detection, stack monitoring, and local measurements);
    - Review of stack release data sharing modalities. 

  • Recent and planned activities at isotope production facilities;
    - Review of ongoing research and development in Chemistry and Xenon absorption technologies. 

  • The broader range of isotope sources: Nuclear power plants, Research reactors, repackaging facilities, hospitals and sources of non-traditional radioxenon isotopes. 


Attendance at previous WOSMIP workshops is not a prerequisite for attendance in 2016. We request experts from organizations that are familiar with the man-made isotope emission issues and/or experts in monitoring and processing of isotope production facilities. As the emissions are not of a health and safety concern, the workshop does not involve discussions related to regulatory matters.

Applicants are requested to visit our website and apply online latest by 28 August 2016.

Financial support may be available to a limited number of participants. Such assistance must be requested at the time of registration (by selecting the relevant box during online registration) and no later than 28 August 2016. Financial support will be considered only for those who have submitted an abstract that will be accepted. Applicants are strongly encouraged to first seek travel and participation funds from non-CTBTO sources.

States Signatories wishing to nominate experts are requested to inform the Provisional Technical Secretariat (see point of Contact) through their respective Permanent Mission by the mentioned deadline for registration.


Applicants are invited to submit an abstract relevant to the objectives of the Workshop via the registration website before the registration deadline (28 August 2016). Applicants will be prompted to select a preference, either poster or an oral presentation.


Applicable to PTS-funded participants only
In accordance with the Staff regulations and rules and Administrative Directives, the PTS will provide the following:

  • A Daily Subsistence Allowance (DSA) that is sufficient to cover the related expenses during the workshop;
  • The PTS travel agent will reserve, issue and send the flight tickets to the participants for the most direct and economic route;
  • Funded participants are not allowed to purchase their own tickets unless, under exceptional circumstances, be authorized to do so and only if this proves to be most cost efficient for the PTS;
  • The PTS will book a hotel and cover the costs for the accommodation and workshop. Participants will receive their remaining DSA upon arrival; and
  • Health insurance for the duration of the workshop will be provided.



Participants should apply for visas, if needed, at the corresponding consular office upon receipt of an acceptance Note Verbale from the Provisional Technical Secretariat, in order to ensure timely processing. 

Health/Accident Insurance
It is strongly recommended that prior to departure all participants should acquire health and accident insurance for the duration of the workshop.
