Radiation field quantities and short technical description of the irradiation facilities of the Forschungsreaktor Neuherberg

The paper reports on the radiation field quantities and the irradiation facilities at the FRN. In particular, the profiles of thermal, intermediary and fast neutrons of the irradiation zones in the core or at the periphery of the core are presented in some detail, and the corresponding spatial fields for the thermal column (thermal neutrons) and the peripheral zone (γ field) are given. These measured data are the basis for planning and carrying out experimental irradiations (in animal experiments, of tissues, cells and the like, detectors, and dosimeters) for the production of isotopes and for sample activations. They substitute for the theoretically determined values given in 'Guidelines for carrying out irradiations at the FRN'. Furthermore, the technical concepts and uses of the irradiation facilities are described in short, and the data of the sample carriers, which are of importance to the user, are given in particular.
