We report the effect of DNA hydration level on damage yields induced by soft X-rays and photo-emitted low energy electrons (LEEs) in thin films of plasmid DNA irradiated in N<sub>2</sub> at atmospheric pressure under different humidity levels. Contrary to a dilute solution of DNA, the number of H<sub>2</sub>O molecules per nucleotide (Γ) in these films can be varied from Γ=2.5 to ~33, where Γ≤20 corresponds to layers of hydration and Γ=33 to an additional bulk-like water layer. Our results indic ...[more]
