Figure 3
Normalized NEXAFS spectra of X. morganii praedicta tissue without previous X-ray exposure and after deposition of an X-ray dose of about 1 GGy at 288.7 eV photon energy. The spectrum of undamaged material is shifted by 0.5 in the y-axis for better representation. The inset in the lower right corner shows an off-resonance micrograph (transmitted intensity) of the sample demonstrating radiation mass loss due to previous line scans (brighter stripes). |
