Overview On Cell Phone Radiation
January 9th, 2010
Cell phones produce electromagnetic radiation. Cell phones discharge certain signals known as radio frequency energy, a form of electromagnetic radiation. There is lot of news these days as to whether cell phones emit radiation which affects our health. Cell phones are placed close to our head which results in direct radiation to the head. Ionizing and Non-Ionizing radiation are the two types of electro magnetic radiation. Radiation can damage human tissue if exposed to high levels of radio frequency radiation. Some of the health problems that can arise due to cell phone radiation are Cancer, Brain tumors, Alzheimer, Fatigue and Headache. According to a survey, higher levels of cell phone radiation can heat biological tissue and cause damage such as burns.
In U.S. every cell phone model is tested and meets FCC standards before it is sold in the market. SAR (specific absorption rate) is a way of measuring the quantity of radio frequency energy that is absorbed by the body. A cell phone or cordless phone should have less than 1.6 watts per kilogram SAR level.
Some of the highest radiation cell phones in United States are as follows: Motorola V195s has 1.6 SAR level. Motorola ZN5, VU204, W385, i335 have 1.59, 1.55, 1.54 and 1.53 SAR levels. Some of the lowest radiation cell phones in United States are as follows: Samsung Eternity SGH-A867, SGH-G800, Soul, Innov8, SHG-T229, and SGH-i450 have 0.194, 0.23, 0.24, 0.287, 0.383 and 0.457 have SAR levels.
