In order to maintain the primary standards and provide calibration services, ARPANSA has a suite of radiation sources. 

These sources cover:

  • kilovoltage X-rays (one source covering the ‘superficial’ range 10 – 100 kVp
  • the ‘orthovoltage’ range 30 – 300 kVp) and megavoltage photons (Cobalt-60). 

In 2009 a medical linac was installed to replace the research linac. This linac provides both megavoltage photon and electron beams, in the range 4 – 25 MeV.

Linac (medical linear accelerator)

Our linac enables us to calibrate therapy dosemeters at megavoltage beam qualities close to those used by radiotherapy treatment centres.

Cobalt-60

This source is used to provide Cobalt-60 calibrations for thimble chambers used in radiotherapy.
