Abstract :
The number of colour centres generated by gamma radiation has been measured with the ESR method; radiation-induced loss was obtained during the steady-state irrediation. By comparing these data, the induced loss in Ge/P-doped GI fibres corresponding to one colour centre is estimated to be 5.5 × 10¿15 dB/km.
