Cell phones emit radiofrequency energy, a type of non-ionizing radiation, which can be absorbed by tissues closest to where the phone is held.To minimize this exposure, the Federal Communications Commission (FCC) has set limits for safe exposure levels for mobile phones. The Specific Absorption Rate (SAR) value on mobile phones is the measure of how much radiation is absorbed by the body, and what is the safest SAR value for cell phones?
Introduction
The use of mobile phones has become ubiquitous in our society. With the majority of adults owning a mobile phone, and countless children as young as 6 or 7 owning their own device, the health effects of mobile phone radiation are becoming increasingly important. One of the most important aspects to consider when assessing mobile phone radiation is the specific absorption rate (SAR) of a device. SAR is a measure of how much energy is absorbed by the body when using a mobile phone and understanding what the safest SAR value is for cell phones is paramount.
What is SAR?
SAR, or specific absorption rate, is a measure of the amount of radio frequency (RF) energy that is absorbed by the body when using a mobile device. It is measured in watts per kilogram (W/kg) and is typically expressed as a value that is averaged over 1 gram of tissue. The SAR value of a device is determined by the amount of RF energy that is emitted from the device, which is regulated by the federal government.
What is the Safest SAR Value for Cell Phones?
The Federal Communications Commission (FCC) has set the maximum SAR value for mobile devices at 1.6 W/kg. This is the highest SAR level that is considered to be safe for the general public. However, some mobile devices, such as those that are designed for children, may have a lower SAR value than 1.6 W/kg.
Are Lower SAR Values Better?
It is important to note that lower SAR values are not necessarily better. In fact, lower SAR values can actually indicate that the device is not working as efficiently as it should be. Therefore, it is important to strike a balance between a device that has a low SAR value and one that is working efficiently.
What Other Factors Should I Consider?
In addition to considering the SAR value of a device, it is important to consider other factors when assessing mobile phone radiation. For example, the amount of time spent on a device, the proximity of the device to the body, and the type of phone case being used can all affect the amount of radiation that is absorbed by the body.
Conclusion
Understanding the SAR value of a device is an important part of assessing mobile phone radiation. The safest SAR value for cell phones is 1.6 W/kg, as set by the FCC. However, it is also important to consider other factors such as the amount of time spent on a device, the proximity of the device to the body, and the type of phone case being used. By understanding the SAR value and taking into account these other factors, people can make informed decisions about the health effects of mobile phone radiation.
