A radiation hardness study of full length (2 m), lead and scintillating fiber calorimeter test modules is reported. The 0.5 GeV LEP Injector Linac (LIL) is used as a radiation source. Test modules, containing a number of different fiber types, are subjected to various dose levels and rates in order to observe light loss and annealing effects. Damage assessment shows the importance of irradiation of complete test modules. Loss in fiber light output during irradiation is reported. Irradiated modules are subsequently probed using a CERN PS, 5 GeV electron beam at various times after irradiation. Integrated light attenuation and damage profiles are measured. Performances of a lead/scintillating fiber calorimeter after radiation damage equivalent to four years running at LHC at rapidity two and radius less than 2 m from the interaction point are predicted.
