Practical course in reference dosimetry

Aims and 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

Course 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.
