Abstract

A comparative study of oxyhemoglobin solution affected by electrons and microwaves was made using Mössbauer spectroscopy. Oxyhemoglobin irradiation by electrons with energy of 10 MeV in doses of ∼1.7, 2.5 and 5.0 kGy led to the rapid oxyhemoglobin deoxygenation with deoxyhemoglobin appearance in Mössbauer spectra as well as to formation of ferric and ferrous compounds as a result of protein destruction. Mössbauer spectra of oxyhemoglobin exposed to microwave heating (2.45 GHz, 900 W) during 5 and 15 s demonstrated an increase of oxyhemoglobin spectral line width and formation of ferric compound.
