According to Dr. Davis, the following tips may help mitigate potential harm from cell phone use:
Children and youth under 20 shouldn’t use cell or wireless phones except in emergencies.
Keep cell phones turned off unless absolutely necessary. When they are on, don’t carry them in your pocket or against your body. Keep the back of the phone, where the antenna is, facing away from your body.
Use a headset or wireless headphone with low power. This removes the phone from right beside your brain.
Use your phone only when/where the signal is good. In marginal areas, it steps up its power output, so you are exposed to more radiation. (more…)
