Be careful to use your cellphone

Tweet

Modern people use cellphone everyday.It is very convenient to keep touch with your colleague,family member or friends. I had working at Wireless Services provider for 4 years.During that time I use cellphone at very high frequency. Then I find a problem:After using Cellphone to talk more than 15 minutes,I feel my head comfortless,I feel heat around my ear and dazed.You know, the peak power emission form a GSM cellphone is about 2 watt.At normally using condition the power emission will less than 1 watt.That radiation can adversely affect humans. If you are live in the city,you can find Base station's antennas on the buildings,they ofen place at the top of buildings or towers.Open the window of your appartment, maybe you can find more than 3 antennas system locate at different places.The power emission form those base-station ofen more than 20 watts.If your house near the antennas please be careful.
