A model for radiolysis of water and aqueous solutions of H2, H2O2 and O2

Measuring the effective diffusion coefficient of dissolved hydrogen in saturated Boom Clay

“…These radicals are chemically reactive and recombine to H 2 , O 2 and H 2 O 2 (Ershov and Gordeev, 2008). Due to the intensive irradiation of both sample and set-up, H 2 will be generated within the pore water of the sample and in the water phase in the vessels.…”

Electron-induced single strand break in the nucleotide of 5- and 6-bromouridine. A DFT study

“…Whether electromagnetic radiation like ␥-rays or particle beams like ␤-rays are used, the principle at work is the same -radiation causes ionization in the target tissue which leads to damage and cell death. The mechanism of damage relies on water ionization, which produces various reactive species such as hydroxyl radicals, hydronium cations and solvated electrons, among others [2]. These entities react with biomolecules in the cell; reactions with DNA seem to be most significant as the biomolecule exists only in two copies, is rarely replaced and is also large, providing a good target for the products of water radiolysis [3].…”

Kinetic Study of Ozone Decay in Homogeneous Phosphate-Buffered Medium

“…For instance, at the majority of the pulse radiolysis experiments where the O 3 /H 2 O/H 2 O 2 chemistry is analyzed, the electron beams used to generate radicals such as hydrated electrons (e aq − ), atomic hydrogen (H • ), hydroxyl radicals, and other chemical species identified by their primary chemical radiation yield, which are not present in water under other circumstances (Boyd et al 1980;Ershov and Gordeev 2008). This experimental environment is very far from the usual one found in typical chemical reactors, so perhaps the chemical environment in radiation chemistry cannot be translated to the conditions of real ozonation equipment.…”
