In order for a radio transmitter of any kind to reach a receiver, it has to emit electromagnetic radiation in the form of radio waves. Radio and TV stations can transmit huge amounts of power, like 50,000 watts, and they do this continuously 24 hours/day. Cell phone towers and public wifi access points transmit at much lower power levels, since they are trying to reach receivers only within a limited distance, like maybe 100 watts, e.g. Cell phones themselves transmit in the neighborhood of 0.3 watts, I believe, and they do this only when they are actually sending data, so when you are not talking on the phone, it is quiet most of the time.

Isn’t there a way to do this (aside from getting rid of it of course) as cell phones are here to stay and even though we do have a wireless router…we don’t use the wireless portion of it.

If you have a cordless house phone, the handset emits radiation only when in use. But the cordless base/recharging station where the antenna is emits radiation constantly (just like a cell phone tower with antennas). If you have a WI-Fi system, your Wi-Fi router also emits radiation constantly. Having a Wi-Fi router is like having a cell phone tower in your house! Your laptop that uses Wi-Fi emits radiation when you connect to the Wi-Fi system (kind of like the cell phone). The problem is with the continuous types of exposure from base stations and for people who have a cell phone glued to their ear for hours a day. The units kids use of texting also emit, but at least when texting they do not hold them to their ear - that helps.
