Mössbauer and positron life-time study of oxyhemoglobin solution irradiated by electrons
Human oxyhemoglobin concentrated solution exposed to electrons with average energy of 10 MeV in doses of 1.7, 2.5 and 5.0 kGy was studied by Mössbauer spectroscopy and positron life-time technique. Precise measurements of Mössbauer spectra of irradiated oxyhemoglobin samples revealed deoxygenation p...

| description | Human oxyhemoglobin concentrated solution exposed to electrons with average energy of 10 MeV in doses of 1.7, 2.5 and 5.0 kGy was studied by Mössbauer spectroscopy and positron life-time technique. Precise measurements of Mössbauer spectra of irradiated oxyhemoglobin samples revealed deoxygenation process and formation of two ferric compounds at 1.7 kGy and ferrous and ferric compounds at 2.5 and 5.0 kGy. Positron life-time parameters showed decrease of the free volume radius and the total free volume in irradiated oxyhemoglobin solutions. |
