The widespread application of research reactors provides multiple opportunities, including radiobiological studies within wide range of physical properties due to specific energy spectrum in each research channels. The article contains numerically estimated theoretical predictions and the experimentally obtained results for chemical dosimeter Fricke with addition of boron acid to perform the evaluation using given 10B concentration. The simulation used the general-purpose Monte-Carlo code to estimate the dose influence from each component. The experiments were taken on the horizontal experimental channel No. 1 of VVR-c reactor at Karpov Research and Development Institute for Physical Chemistry, Obninsk, Russia, which provided mixed gamma-neutron field together with fast and thermal neutron components. The research found the satisfactory correspondence between simulated and measured values, but also the requirements and necessity of further studies was demonstrated in order to adjust experimental dosimetry methods for mixed field evaluation. Generally, the obtained results are of practical use as multidisciplinary basis for multiple physical- and radiobiological-oriented studies in the mixed radiation field, and are an integral part in future opportunities aimed on the building medical-oriented facility for neutron and neutron-capture techniques on the VVR-c reactor.
