Summary

Some radiation accidents can be accompanied by high local clinically important absorbed doses. In such cases, local doses can be estimated by measuring by electron paramagnetic resonance (EPR) spectrometry radio-induced radicals in bone tissues of radiation victims. To get a precise and a reliable assessment of absorbed dose by EPR on human bone tissue, a lot of additional information must be obtained: energy response to different types of irradiation, radiation sensitivity, impact of such physiological factors as necrotic and metabolic processes, etc. In order to fill some of these existing gaps, this work is dedicated to the study of the energy dependence of EPR radio-induced signals of human bone tissue to photons and the determination of their relative sensitivity to fission neutrons.
