Computer evaluation of direct and indirect damage induced by free and DNA‐bound Iodine‐125 in the chromatin fibre

Abstract

The distribution of damage complexity for free and DNA-bound I-125 is presented. We obtained more than 1.3 DSB per decay, with nearly equal contributions from direct and indirect effects. However, for the most complex type of damage, located at the decay site, the direct effect is about 70% of the total number. To show the protective effect of histones, simulations were carried out with and without the presence of histones.
