IAEA Services for SSDLs


The IAEA provides bilateral comparisons for the SSDLs. The comparison programme enables SSDL Network members to verify the consistency of their national standards and validate the calibration procedures used. The IAEA has comparison programmes for radiation therapy, radiation protection and diagnostic radiology. A calibrated IAEA transfer ionization chamber is sent to a participating SSDL for calibration according to their own calibration procedures. The IAEA evaluates the comparison results and prepares a comparison report. If a result is not within the acceptance limits, the IAEA works with the SSDL to resolve any discrepancies.
