Figure 3: Evaluation of DNA damage induced by 50 Hz and 0.5 mT MF for 30 days 24 h/day in the brain cells of newborn rats processed by comet assay. (a) represents cells without visible DNA damage type (0), (b) represents cells with symptom of increasing DNA damage types (1, 2, and 3), and (c) represents cells with a major DNA damage (type 4).
