✦ Synopsis

We report oo measuremeats of radiation hardness of plastic scintillating fibres to be used for fibre calorimetry. Fibres were irradiated with a 60~0 r-source and the effects oo the emission and on the attenuation of sciotillatioo light in a number of differeot fibre types were studied. A Monte Carlo study that simulates radiation damage to a compensating leadlfibre calorimeter and predicts the impact on the performance is described. We infer from these results that with the best fibres that are preseotly commercially available the effects on calorimeter performaoce appear lo be within acceptable limits up to 7Mrad doses deposited in the sciotillator at the peak of the damage.
