Since 1976, the IAEA has maintained a register of dosimetry laboratories in the IAEA/WHO SSDL Network. The Network includes SSDLs either as full or as provisional members. PSDLs and international organizations are included as affiliated members. Full members are requested to submit their annual report to the IAEA. Up-to-date information about provided calibration services based on these annual reports can be found in DOLNET. DOLNET is updated on a biannual basis, including once after every Annual Reporting period. If you wish to update the services provided by your laboratory, please follow the instruction in the section Access to Data Entry.

The services available in DOLNET should fulfil the SSDL Network Charter requirement. The search function makes it possible to search for the specific services or check services in a specific country.
