  "main_findings": "Purified plasmid DNA exposed to nonthermal microwave radiation (2.00–8.75 GHz) showed single- and double-strand breaks detected by agarose gel electrophoresis. DNA damage depended on the presence of small amounts of copper and varied with microwave power and exposure duration; cuprous (not cupric) ions mimicked the microwave effects.",
