> What are some simple things that each of us can do to reduce the risk of harm from radiation from cellphones and other wireless devices? > First, minimize your use of cellphones or cordless phones — use a landline whenever possible. If you do use a cellphone, turn off the Wi-Fi and Bluetooth if you’re not using them. However, when near a Wi-Fi router, you would be better off using your cellphone on Wi-Fi and turning off the cellular because this will likely result in less radiation exposure than using the cellular network. > Second, distance is your friend. Keeping your cellphone 10 inches away from your body, as compared to one-tenth of an inch, results in a 10,000-fold reduction in exposure. So, keep your phone away from your head and body. Store your phone in a purse or backpack. If you have to put it in your pocket, put it on airplane mode. Text, use wired headphones or speakerphone for calls. Don’t sleep with it next to your head — turn it off or put it in another room. > Third, use your phone only when the signal is strong. Cellphones are programmed to increase radiation when the signal is poor, that is when one or two bars are displayed on your phone. For example, don’t use your phone in an elevator or in a car, as metal structures interfere with the signal. Is there any science to this at all? However tenuous it may be I’m curious about the underlying rational for these recommendations. Particularly the first and third. They come across as a bit... superstitious? And unfortunately the article make no attempt at explaining the “why” behind the “what”.
