Dose Course 2018_Flipping book

Summary: IAEA TRS-483 dosimetry COP for reference and relative dosimetry in static small MV photon fields:

✓ Important concepts on the definition of field size

✓ Definition of beam quality (small fields WFF and FFF beams)

✓ Formalism for reference and relative dose determination

✓ Choice of suitably small detector which is known to minimally perturb fluence

✓ Correction for volume averaging (FFF beams)

✓ Account for energy dependence of detector (daisy chaining)

✓ Field output correction factors: if greater that 5% the detector is not recommended for use in small fields.

✓ Guidance on experimental setup

✓ Corroboration of data
