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
