Irradiation produces
luminiscence
Light is guided through optical fiber
Cerenkov light and luminiscence
have different wave lenghts
Organic scintillator
(W1 Standard Imaging)
BUT
to a photomultiplier
The signal is proportional to
absorbed dose
When we irradiate optical
fiber Cerenkov light is
produced
Cerenkov light depends on the
length of fiber irradiated, not
proportional to dose
