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 dosimetry standards. The SSDL dose audit programme checks the reference beam outputs in the field of radiation therapy and radiation protection.

A passive dosimeter is provided to a participating SSDL, 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 report is issued. If any result is not within the acceptance limits, the IAEA works with the SSDL to resolve any discrepancies.
