3. Detector response (detector perturbation effects)
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)
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.
