Abstract FLUKA simulations were used to design a dosimetry monitoring system for the typical electron acceleration experiments in the E6 area of the ELI-NP building. The FLUKA geometry of the E6 experimental area was built by using data extracted from the latest available version of the corresponding Catia file, including all the building and beamline transport elements. Based on that geometry we calculated H*(10) in a Cartesian binning over E6 and neighbouring areas for the worst case scenario: a 38 GeV Gaussian electron source term. The fluence rates of the secondary prompt radiation field components were mapped throughout the E6 experimental area. The results were used to determine the most important contributor to the dose and the areas with the highest exposure, as well as the positioning of the detectors for radiation monitoring. We propose solutions for some practical issues: proper choice of the detector type and proper detector positioning in accordance with the characteristics of the radiation field (dose range, field components, energy ranges).
