Cell phones, most everyone has one. They have evolved from a large, heavy device that you would carry in a shoulder bag to a small device that can be easily slipped into a pocket. Back then they were just used for calling and not many people had one. But now millions of people would not be able to go a day with out a cell phone.

It all depends on a person's usage of their cell phone.

Now that I have you thinking twice about answering your cell phone that is buzzing on the table next to you; I will tell you a little more about how cell phone radiation is measured. All radiation levels are controlled by the Federal Communications Commission (FCC) and the Food and Drug Administration (FDA). They have come up with a “safe level” that all the manufactures can not exceed.

These limits are given in terms of a unit referred to as the Specific Absorption Rate (SAR), which is a measure of the amount of radio frequency energy absorbed by the body when using a mobile phone. The FCC requires cell phone manufacturers to ensure that their phones comply with these objective limits for safe exposure. Any cell phone at or below these SAR levels (that is, any phone legally sold in the U.S.) is a "safe" phone, as measured by these standards. The FCC limit for public exposure from cellular telephones is an SAR level of 1.6 watts per kilogram (1.6 W/kg). (FCC)

You can find the SAR level of your phone by either looking it up in the information that came with your phone, on the phone manufacturer's website, or by using the FCC code on your phone to look up the SAR data on the FCC website. Generally the SAR data shown is the data received when the phone is at max transmitting power when transmitting speech or data. Very rarely do cell phones transmit on the maximum power possible. They are
