Abstract	The complex nature of the radiation environment in various high-energy physics facilities necessitates the use of different kinds of radiation monitors. The detectors used could be either passive or active and need dedicated readout electronics. The present study was conducted at GSI Helmholtzzentrum für Schwerionenforschung in Cave A where different kinds of radiation detectors were tested in parallel in the secondary radiation field generated by a 1-GeV/u 56Fe ion beam impinging a thick polyethylene target, and their responses were compared with the Monte Carlo code FLUKA simulations. Thermoluminescence-based passive detectors from GSI, ionization chamber-based radiation monitors developed by CERN, WENDI-II, and wide-range photon detectors from Berthold and Thermo Fisher were studied in this campaign. The study showed good agreement between the temporal responses of the various detectors, and comparison of the ambient dose equivalents measured with the simulations showed agreement of over 40% for all the detectors. In addition, two versions of radiation monitoring front-ends developed at CERN were directly compared and the relative mismatch in measurement was consistently less than 10%.
