IAEA Services for SSDLs

Dose audits

The IAEA provides radiation dosimetry audit services to the SSDL Network members. The programme helps the SSDLs to verify the implementation of their national dosimetry standards. The SSDL dose audit programme checks beam calibrations in the field of radiation therapy and radiation protection.

In the audit process, first a passive dosimeter is provided to the participating SSDLs to be irradiated under reference conditions with a specified air kerma for radiation protection level audits and absorbed dose to water for radiation therapy level audits. Then, the irradiated dosimeters are sent back to the IAEA to be evaluated. After the evaluation, a confidential report of the results as well as scientific support to resolve any possible discrepancies are provided to the SSDL.
