- Minimize use of cell phones or cordless phones. Use a landline whenever possible.
- Keep cell phones away from our heads and bodies. Ten inches from your body, as compared to one-tenth of an inch, results in a 10,000-fold reduction in radiation exposure. Store your phone in a backpack or purse and text or use a wired headset or speakerphone for calls.
- Use cell phones only when the signal is strong. A new study by the California Department of Public Health found up to a 10,000-fold increase in electromagnetic radiation exposure when reception was poor (when you have one or two bars on your phone).
