ARPANSA runs the Practical Reference Dosimetry Course for external beam radiotherapy. Running over four days, the course covers the theory and provide hands-on experience in all areas of radiation dosimetry for external beams.

The dates for the 2025 Practical Reference Dosimetry Course are 17-20 March 2025. 

The course is aimed at experienced ROMPs (Radiation Oncology Medical Physicists), registrars and qualified medical physicists seeking a refresher course, concentrating on TRS-398 Revision 1 and TG-61. The course is hands-on as well as delving into the physics behind the protocols.

The four day course consists of lectures by ARPANSA staff and senior hospital physicists and includes eight practical sessions with a formal assessment at the end of each day. A certificate will be presented upon successful completion of the course.

At the end of the course, students will:

  • have a good fundamental theoretical and practical understanding of all aspects of reference dosimetry for kV X-rays, high-energy photons, and electrons
  • be familiar with the Australian primary standards for air kerma and absorbed dose to water used in reference dosimetry, their units and uncertainties
  • understand the ACPSEM-recommended codes of practice for kV X-rays, MV photons and electrons, and their practical application to clinical beams
  • understand correction factors and be able to calculate uncertainties in reference dosimetry.

Topics include:

  • Quantities and units
  • Uncertainty calculations and reporting uncertainties
  • Dosimetry protocols for kV and MV photons and MV MeV electrons (TRS-398 Revision 1, TG-61)
  • Measuring beam quality index, output, and output factors
  • Primary standards
  • Legal metrology and regulatory framework
  • Understanding your equipment
  • Ion chamber theory
  • Small field dosimetry

This course is held on an annual basis and is approved for 40 CPD points.
