Massachusetts Department of Public Health: Best Practices to Reduce Wireless Exposure

Massachusetts Department of Public Health

Minimizing Exposure to RF
Given the lack of scientific consensus on the potential health risks from these sources, attention is often focused at minimizing exposure.  Below are common recommendations and include those for both cell phone and non-cell phone sources:
Use wired communication devices instead of wireless devices
  • Consider a wired Local Area Network (LAN) instead of wireless, and wired connections to computers and other individual devices.
  • Use a wired landline instead of a cell phone for everyday calls
Limit children’s use of cell phones except for emergencies
  • Don’t offer the phone as a toy.
  • If your children use a phone to play games, switch on airplane mode. A phone in airplane mode will stop RF (radio frequency) transmission but still have some magnetic field exposure.
Keep cell phones and other sources at a distance
  • The strength of the RF emission or exposure is one fourth lower at a distance of two inches and fifty times lower at three feet. 
  • Whenever possible, use the speaker-phone mode or a plug-in headset rather than holding a phone to your ear. 
  • A wireless “Bluetooth” headset can have less exposure than a cell phone, though data seem inconsistent on how much less exposure.
  • While on a call, keep the phone away from your body (e.g., on a table in front of you instead of your pocket).
If using wireless devices like computers, laptops, tablets, and printers, place the wireless router away from where children and adults usually spend time.
  • Store your cell phone and other devices like routers away from your body.
  • Don’t store your phone under your pillow or clipped on your belt, especially if you are pregnant. 
  • Switch the phone to “airplane” or “off-line” mode when not using for communication such as for some other function like as an alarm clock.  Power phones 100% off before you carry them near your body to avoid all exposure.
Turn off routers when wireless devices are not in use.
  • Text when possible
  • Texting emits less radiation than voice calls.
  • Avoid using your cell phone when the signal is weak or when moving at high speed, such as in a car or train.
  • These types of use automatically increase power to a maximum as the phone repeatedly attempts to connect to a new relay antenna.  Radiation levels are significantly higher when your signal is poor.
