3. Detector response (detector perturbation effects)

Detector related conditions: when the particle fluence sampled by the detector differs, sometimes substantially, from the fluence that exists in a homogeneous medium in the absence of the detector.

Detector size:

a) Volume averaging (the size of the detector relative to the size of the radiation

field)

Detector composition:

b)

Density of sensitive volume of the detector

c) Atomic properties of the sensitive volume of the detector

d) Influence of detector components other than its sensitive volume (extra-

cameral components)
