The Optical And Epr Spectra of Fe(2+) and Fe(3+) Ions in the Blood of the Chernobyl Clean-Up Worker

2007

Electron paramagnetic resonance (EPR) and optical absorption studies of blood were provided for the group of Chernobyl’s NPP accident clean-up workers examined in the Center of Occupational and Radiological medicine of P.Stradins Clinical hospital of Medical Academy of Latvia. The EPR spectra for blood have been studied at low temperature. It is shown that in blood the ion Fe3+ of methemaglobin is in low-spin state with g = 2.3 and in the high spin state with g=6. We observed the additional absorption bands 500 nm (shoulder) and 630 nm in absorption spectra of blood of Chernobyl clean-up worker who has erythrocytosis.
