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:
- to improve dosimetric accuracy, particularly in radiation therapy, radiation processing and radiation protection, by supporting centres and laboratories for the transfer of radiation standards and for the creation and distribution of knowledge in applied dosimetry;
- to promote further the exchange of experience between the members and affiliated members, and to provide support to each other where necessary;
- to establish and facilitate links between the members and the international measurement system for radiation measurements, through PSDLs; and
- to promote the compatibility of methods applied for calibration and performance of dosimetry in order to achieve uniformity of measurements throughout the world.
