Nuclear and Radiation SafetyThroughout the Icelandic Presidency, the CSO followed and supported the work of theCBSS Working Group on Nuclear and Radiation Safety (WGNRS) to prepare a JointDeclaration on the Exchange of Air Radiation Monitoring Data on the basis of the Agreement on the Exchange of Radiation Monitoring Data, as of 7 June 2001. At themeeting in Reykjavik in January 2006, the Icelandic member of the WGNRSintroduced the draft joint declaration to the CSO, and at its meeting in Stockholm inMarch, the Chairman of the WGNRS presented the final version to the CSO. At thismeeting, the CSO adopted the Joint Declaration.Air radiation monitoring data (measurements of aerosol bound radionuclides) areuseful for routine measurements as it is the most sensitive method to detect smallemissions of radioactive sources, but also for emergency measurements, as airmeasurements could allow for earlier notification in case of an accident.Further, the CSO worked to ensure full participation in the CBSS Working Group onNuclear and Radiation Safety in order to enhance the work of the Group. The IcelandicPresidency hosted a meeting of the WGNRS in Iceland.
