Practical Course in Reference Dosimetry

Aims & Objectives

  • Develop a good fundamental, theoretical and practical understanding of all aspects of reference dosimetry for kV X-rays, photons, electrons and HDR brachytherapy sources
  • Be familiar with the UK primary standards used in reference dosimetry
  • Understand the current Codes of Practice for kV X-rays, High-energy photons and Electrons, and their application
  • Be able to carry out basic metrology in reference dosimetry, including the application of correction factors and evaluation of uncertainties

Module Details

The course will consist of introductory lectures that cover:

  • Basic quantities and units
  • Overview of dosimetry and evaluation of uncertainties
  • Practical advice on the handling and maintenance of secondary standard and field instruments with emphasis placed on recognising and dealing with measurement problems

And four separate practical sessions on:

  • Dosimetry of kV X-rays, covering both in-air and in-water measurements
  • High-energy photons (Co-60 gamma-rays and 4 MV to 19 MV X-rays)
  • Electrons
  • High-dose-rate (HDR) brachytherapy, including a session covering check source measurements

The practical sessions will cover all areas of measurement including basic metrology, estimating uncertainties and applying corrections.
