According to the Federal Communications Commission (FCC), the highest Specific Absorption Rate (SAR) value for cell phones used in the United States is 1.6 watts per kilogram (W/kg). SAR is a measure of the rate at which energy is absorbed by the body when exposed to a radio frequency (RF) electromagnetic field and is used to indicate the safety level of a particular phone.
What is the Highest SAR Value?
Introduction
The Specific Absorption Rate (SAR) is a measure of the rate of energy absorbed by a unit of mass when exposed to a radio frequency (RF) electromagnetic field. It is measured in units of watts per kilogram (W/kg) and is used to measure the safety of RF-emitting devices, such as cell phones. SAR values are determined by the amount of RF energy a person is exposed to when using a device, and is an indication of how much energy is actually being absorbed by the user’s body. The higher the SAR value, the more energy is being absorbed and the greater the potential health risks. So, what is the highest SAR value?
What is the Maximum Permissible SAR Value?
The maximum permissible SAR value is the highest level of RF energy exposure that is considered safe by national and international standards. Different countries and organizations have different standards for SAR values, but the most common is the limit set by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). According to the ICNIRP, the maximum permissible SAR value for the general public is 2.0 W/kg averaged over 10 grams of tissue. This means that any device with a SAR value higher than 2.0 W/kg has the potential to cause harm to the user.
How is SAR Value Measured?
SAR values are measured using a device called a SAR meter. This device is used to measure the amount of RF energy that is being absorbed by a person when using a device. The SAR meter measures the amount of power that is being absorbed by the body, which is then converted to a SAR value. The higher the power absorption, the higher the SAR value.
What is the Highest Reported SAR Value?
The highest reported SAR value is 10.2 W/kg, which was reported for a cell phone tested in the United States. This SAR value is far higher than the maximum permissible SAR value set by ICNIRP, and is considered to be unsafe. In addition, this SAR value is also much higher than the SAR values reported for most other cell phones.
What Can I Do To Reduce My Exposure to High SAR Values?
The best way to reduce your exposure to high SAR values is to limit your use of cell phones and other wireless devices. Try to keep the device away from your body as much as possible, and limit the amount of time that you use the device. It is also important to avoid using your device in areas where the signal is weak, as this can cause the device to emit higher levels of RF energy. Additionally, if you must use your device in areas with weak signals, make sure to limit your exposure by using a headset or speakerphone.
Conclusion
The highest SAR value reported is 10.2 W/kg, which is far higher than the maximum permissible SAR value set by ICNIRP. It is important to limit your exposure to high SAR values by limiting your use of cell phones and other wireless devices, avoiding using the device in areas with weak signals, and using a headset or speakerphone when needed. Doing so can help reduce your exposure to potentially harmful levels of RF energy.
