Electron paramagnetic resonance identification of irradiated cuttlefish (Sepia officinalis L.).
Gamma-ray irradiated fresh cuttlefish bone display very intense Electron Paramagnetic Resonance (EPR) spectra, which could be attributed to five different centers, including CO2-, previously observed in irradiated carbonates. All centers display a positive correlation with the absorbed dose, described by linear or saturation type dependencies. During 36 h of isothermal annealing at 100 degrees C, three of them decayed with time exponentially, one remained constant, while the EPR spectrum amplitude of the fifth increased.
