  The upcoming European XFEL will be built at a length of approx. 3.4 km between the campus of the Deutsches Elektronen-Synchrotron DESY at Hamburg and Schenefeld at Schleswig-Holstein for commissioning in 2015. The XFEL utilizes various electronic systems for machine control, diagnostics and safety. To achieve a cheap and compact accelerator construction, the beam pipe and its nearby electronic supply systems are located inside the same tunnel, charged by an evident amount of radiation in certain sections of the XFEL. To insure the lifecycle and function of electronics and magnetic structures like undulators in these XFEL radiation fields, all electronic systems located inside the tunnel will be sufficiently shielded according to pre-estimated radiation levels. In addition, these electronics and the undulator parts will be monitored for the impact of Gamma- and Neutron-radiation by a new versatile and compact radiation monitor system. It measures the accumulated dose in the electronic cabinets along the XFEL to ensure an exchange of radiated parts before significant radiation damage occurs. First prototype measurements at different radiation sources will be presented.
