Australian primary standards

Australian Primary Standards Index:

ARPANSA maintains the primary standards for the dosimetry of ionisation radiation for Australia.

The standards are maintained under an authorisation from the National Measurement Institute under the National Measurement Act.

As a part of the authorisation, ARPANSA participates in international comparisons and international metrology organisations. ARPANSA's Calibration and Measurement Capabilities (CMCs) and comparison results are listed in the Key Comparison Database (KCDB).

The primary standards are all detectors of radiation. For megavoltage radiation ARPANSA maintains a graphite calorimeter. For kilovoltage radiation, ARPANSA has two free air chambers. At 60Co a standard ionisation chamber is also maintained for determination of air kerma.
