The Effect of Environment upon DNA Free Radicals
Since 1985 a continued effort has been made to understand the primary damage caused by direct radiation effects to the constituents of the DNA molecule. The main motivation for initiating these studies was the report from a Swedish group (Gräslund et al. 1971). Using ESR spectroscopy it was proposed that in oriented fibres of DNA mainly two radical species are formed and trapped at low temperatures.
