Radiation damage events at low and moderate energies (up to 400 ev) are studied by machine calculations in a model representing copper. Orbits of knock-on atoms are found and the resulting damaged configurations are observed to consist of interstitials and vacancies. Thresholds for producing permanen...

X-ray diffraction (XRD), small angle x-ray scattering (SAXS), and extended x-ray absorption fine structure (EXAFS) were measured before and after irradiation.A molecular dynamics (MD) simulation (for a bigger system than in our previous work) was performed to simulate radiation damage of an...
The collision of carbon ions on DNA and RNA bases thymine, uracil and 5-halouracil is investigated with regard to the action of radiations on the biological medium. The charge transfer process is studied theoretically in a wide collision range by means of ab initio quantum chemistry molecular ...
SUMMARYChromatin compaction is thought to influence the severity of radiation-induced DNA damage. We assessed how chromatin state affects DNA double-strand break repair within eu-/heterochromatin domains in male germ cells by profiling the spatiotemporal dynamics of γ-radiation-induced γH2AX foci in...

It is reported that alloys with Cr concentration around 9 at% have a minimum influence on the shift of the ductile-to-brittle transition temperature (DBTT) among all the Fe–Cr alloys [6,7]. Many study was also conducted in Fe to investigate the radiation-induced damage evolution in ...
