(A)-(D)[25]reflect water decomposition by the concentration of radiolysis byproducts. (B) is an extension of (A) and is air free pure water. Decomposition ensues until H2 in excess of ROS. (C) is effect of dissolved O2 in excess of H2 to promote decomposition. (D) is effect of dissolved hydrogen in excess of O2 to scavenge. (E) [24] Shows effect of O2 as a biological radiosensitizer. N2 is also shown which raises the question of what the effect of H2 would be.
