Cell phone radiation levels
Shows how much radiation is released when the phone is inactive in your pocket. Then switched to airplane mode; O readings of radiation released. So it might be a good idea to keep the phone in airplane mode and taking it off when you use it. Although that means you wont have it for an emergency. Watch this video and you decide.
Faraday pouches like the block it pocket work well also. Rendering the phone useless while inside. Makes me want to put one around the smart meter outside my house.
