My thanks to the Center for Safer Wireless in Washington DC for the following safety tip regarding E-Readers:
"Wired devices are the safest way to go. For those who gave or received e-readers as Christmas gifts (Nook, Kindle, tablets, iPads, Kobo) you can reduce your exposure to pulsed radiofrequency radiation by simply turning off the wireless signal on these devices. When you are reading an e-book, newspaper, or magazine, you don't need a wireless connection with the e-reader. To disable the wireless signal, each device is different. Search for phrases such as "turn off wireless signal" or "disable wireless network connection". Use the wireless connection only when accessing the Internet (such as when downloading a book or an application) and turn off the wireless signal when you are finished with the activity. Also, with the wireless disabled, you won't have to re-charge your e-reader as often.
“To reduce health risks, we recommend that parents impose rules for children using an e-reader. In addition to the above recommendations, children shouldn't lay the e-reader on their bodies. Instead, they can place the devices on pillows in their laps or on desks and tables. Not only is the pulsed radiofrequency radiation a concern but also the alternating current magnetic fields from the devices. Keeping a distance between young bodies and the devices helps to reduce health risks.“Adults can follow these rules for e-readers and when using a wireless laptop.”
Everyone must ensure maintaining a certain distance between their bodies and wireless devices. Recently, a scientist told me about a woman whose pregnancy required her confinement to bed from the second month. Her baby was born with birth defects. Refer to my articles on the effects of wireless devices on pregnancies (“Dangrs to Pregnant Women of Wireless Technologies") and on sperm ("Is Radiation from Wi-Fi-Connected Laptops Nuking Sperm?")
