What is cell phone radiation and how is it measured?
Cell phone radiation refers to the electromagnetic fields emitted by mobile devices, including radiofrequency (RF) energy. This type of radiation is used to transmit and receive signals between the phone and the nearest cell tower. To measure cell phone radiation levels, a unit called the Specific Absorption Rate (SAR) is used. SAR measures the amount of RF energy absorbed by the body when using a mobile device. In the United States, the Federal Communications Commission (FCC) sets a maximum SAR limit of 1.6 watts per kilogram (W/kg) for mobile devices.
The SAR value is typically measured in a laboratory setting using a standardized testing procedure. During the test, a phone is placed in a simulated environment and a sensor is used to measure the amount of RF energy absorbed by a model of the human body. The results are then used to calculate the SAR value, which is usually expressed in W/kg. It’s worth noting that SAR values can vary depending on several factors, including the type of phone, the frequency of use, and the distance between the phone and the body. As a result, it’s essential to check the SAR value of a specific phone model to understand its radiation levels.
