The physicochemical characteristics of 2-deoxy-D-ribose moieties in DNA strands are important to understand biological radiation stress. So, the X-ray absorption near edge structure (XANES) of 2-deoxy-D-ribose within the energy region around the oxygen K-shell absorption edge was measured. 2-deoxy-D-ribose was exposed to 3 energies of X-rays, i.e. 526.3 eV (below O 1s→σ*), 537.8 eV (at the absorption peak of O 1s→σ*) and 552.6 eV (above O 1s→σ*) for given periods. Slight differences in spectral changes were seen in the each irradiation energy, suggesting in fact that the chemical state and following rearranged chemical structure of 2-deoxy-D-ribose may be different between the three irradiation energies.
