Effects of 2.0 GHz, 40 dBm RF-EMF exposure on ROS levels and related enzymatic activity in SB34 [ure-o] cells. a Relative ROS level in SB34 [ure-o] cells after RF-EMF exposure versus control. b Enzymatic activity of SOD after RF-EMF exposure versus control. c Enzymatic activity for CAT after RF-EMF exposure versus control. All data represent three independent experiments. Bars represent S.D. of the mean. “*” means P < 0.05, compared with the control, while “**” represents P < 0.01, with respect to the control
