Mossbauer study of oxyhemoglobin solution exposed to electrons and microwave heating

A comparative study of oxyhemoglobin solution affected by electrons and mic rowaves was made using Mossbauer spectroscopy. Oxyhemoglobin irradiation by electrons with energy of 10 MeV in doses of similar to 1.7, 2.5 and 5.0 kG y led to the rapid oxyhemoglobin deoxygenation with deoxyhemoglobin appeara nce in Mossbauer spectra as well as to formation of ferric and ferrous comp ounds as a result of protein destruction. Mossbauer spectra of oxyhemoglobi n exposed to microwave heating (2.45 GHz, 900 W) during 5 and 15 s demonstr ated an increase of oxyhemoglobin spectral line width and formation of ferr ic compound.
