Electron Attachment to Biologically Relevant Molecules: Towards the Initial Molecular Steps in Radiation Damage
The interaction of low energy electrons with biomolecules is directly related to the old problem of radiation damage. After the discovery of X-rays, radioactivity and nuclear fission it became soon obvious that the exposure of living beings to high energy radiation (particles and photons) can result in fatal effects for the concerned individual. The variety of such effects is subsumed under the term radiation damage. It includes damage of biological material on a short time scale, i.e. the immediate collapse of living cells eventually resulting in the death of the individual within hours or days but also effects appearing on a much longer time scale. Instead of a complete damage of cells, radiation can result in genotoxic or mutagenic effects, i. e. strand breaks in DNA or change of its sequence (genetic expression).
