Gamma-ray irradiated fresh cuttlefsh bone display very intense Electron Earamagnetic 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 oC, three of them decayed with time exponentially, one remained constant, while the EPR spectrum amplitude of the fifth increased.
