Dose Course 2018_Flipping book
Point detectors for in vivo dosimetry
pros
cons
No cables/No bias Tissue-equivalence (no E dependence) Permanent storage of dose (swallow traps) No T or Dose rate dependence Different shapes
No on-line measures Accurate read-out needs care Need of Post-processing Limited dose-response lineal.
TLD
No bias On-line measurements Long life High sensitivity
Non tissue-equiv. (E depend) Dose-rate dependence Sensitivity var. Accum. D Sensitivity variation witn T
Diode
Non tissue-equiv. (E depend) Limited life-time Low sensitivity
No cables/No bias (depends on manufact.) “On-line” measurements No dose-rate dependence No T dependence (with some precautions)
