Abstract
The effect of ionizing radiation on glasses in the system SiO 2-CaO-Na2O-Fe2O3 is investigated as a function of iron concentration or / and irradiation dose by a pre-edge analysis at the iron K-edge. While reduction phenomenon is clearly observed for large irradiation doses (5 C), the effect of irradiation for intermediate doses is more challenging to interpret. Comparison between X-ray absorption measurements, colorimetry results and Electron Paramagnetic Resonance measurements suggest that iron environment may be modified without the ions being reduced. © 2009 IOP Publishing Ltd.
