Samples of copper, aluminium and stainless steel with well-characterized elemental compositions were irradiated in the stray radiation field created by a 2.5 GeV electron beam hitting a copper dump. After the irradiation the induced activity in the samples was analysed with gamma-ray spectrometry. The beam intensity monitoring with a current transformer was verified in an additional study by irradiating gold-foils stacked in between copper blocks and by analysing the production of 196 Au for

Excellent agreement between measurement and simulation within a few percent was obtained for the gold-foils irradiation confirming the accuracy of the beam monitoring. The benchmark of the FLUKA results with the data of the material samples showed good agreement, for many nuclides within 30%.
