IAEA/WHO SSDL network
A Secondary Standards Dosimetry Laboratory (SSDL) is a laboratory which has been designated by competent national authorities to undertake the duties of providing the necessary link in the traceability of radiation dosimetry to national/international standards for users within that country. An SSDL is equipped with secondary standards which are traceable to the primary standards of laboratories participating in the international measurement system (Primary Standards Dosimetry Laboratories (PSDLs) and the Bureau International des Poids et Mesures (BIPM)).
The IAEA/WHO SSDL Network is an association of national SSDLs which agree to cooperate in promoting the objectives of that Network under international auspices. Its objectives are:
- Accuracy: to provide dosimetry services and create and distribute knowledge in radiation dosimetry in order to improve the accuracy level in dose measurements;
- Traceability: to establish and facilitate links between end users of dosimeters, the SSDL members and the SI system for radiation measurements;
- Consistency: to promote international recommendations on methods applied for calibration and performance of dosimetry in order to achieve consistency of measurements in all countries;
- Cooperation: to promote further the exchange of experience between the members and the metrology community, and to provide support to each other where necessary
