“…Most studies also concluded with amino acid losses. In a review of these pioneering works, Braams and Van Herpen (1964) emphasized the need for information at the molecular and supramolecular levels to go further in the understanding of the fine mechanisms of radiation-induced damages in tissues. Nevertheless the field of the structural analysis of radiation damages in biological materials remained nearly unexplored for decades until a few years ago with the first studies of synchrotron radiation-induced damages in protein crystals.…”
