Phone Radiation: FCC Says Don’t Compare Single Specific Absorption Rate (SAR) Values To Shop For Phones

FCC-do-not-compare-single-sar-levels-for-cell-phones

Introduction

Cell phones have become an integral part of our daily lives, but with the increasing use of these devices, concerns about their safety have also risen. The Specific Absorption Rate (SAR) is a measurement of the rate of radiofrequency (RF) energy absorption by the human body from cell phones. In this article, we will explore what SAR is, how it is measured, what it indicates, and what it does not show.

SAR Testing

To determine the SAR values of cell phones, manufacturers are required to conduct SAR testing. The testing is done using standardized models of the human head and body that simulate the RF absorption characteristics of different human tissues. During the testing, the cell phone is positioned in various common positions next to the head and body and is tested while operating at its highest power level in all the frequency bands it operates. The SAR values recorded during the testing are used to demonstrate compliance with the Federal Communications Commission (FCC) guidelines and to ensure that the cell phone does not exceed the maximum permissible exposure levels set by the FCC.

What SAR Shows

The SAR values recorded during the testing are the highest single measurements taken for each frequency range used by the particular model of the cell phone. These values indicate the highest possible RF energy absorption for a user and ensure that the cell phone does not exceed the maximum levels of consumer RF exposure permitted by federal guidelines.

What SAR Does Not Show

It is important to note that a single SAR value used for FCC approval does not account for the multitude of measurements taken during the testing. Cell phones constantly vary their power to operate at the minimum power necessary for communications, and operation at maximum power occurs infrequently. Therefore, cell phones cannot be reliably compared for their overall exposure characteristics based on a single SAR value, according to the FCC.

The Bottom Line

All cell phones must meet the FCC’s RF exposure standard, which is set at a level at which laboratory testing indicates potential adverse health effects could occur. If you are concerned about your exposure to RF energy, the most effective measures to reduce it are to hold the cell phone away from your head or body and to use a speakerphone or hands-free accessory to maintain a safe distance.

SAR Shortcomings

Limited Information: The SAR values recorded during testing are the highest single measurements taken for each frequency range used by the particular model of a cell phone. These values provide limited information about the amount of RF exposure under typical usage conditions and are insufficient to compare individual cell phone models reliably.

Not Representative of Actual Usage

The SAR values recorded during testing are based on the cell phone operating at its highest power level but at distances away from the body that may not be practical and in only specific positions, which may not represent the way the cell phone is actually used by the user. This means that the SAR values recorded during testing may not accurately reflect the RF exposure of a user during typical usage.

Does Not Account for Variables

A single SAR value used for FCC approval does not account for the multitude of measurements taken during the testing and does not account for young phone users. This means that cell phones cannot be reliably compared for their overall exposure characteristics based on a single SAR value.

Does Not Consider Individual Usage Patterns

The SAR values recorded during testing do not account for individual usage patterns, such as the way a user holds the cell phone or the proximity of the cell phone to the head or body. This means that the SAR values recorded during testing may not accurately reflect the RF exposure of a particular user.

Only Regards Thermal Hazards

SAR values only consider thermal hazards from RF exposure and do not account for other potential health effects from RF exposure.

Does Not Account for Children’s Thinner Skulls

SAR values do not take into account the thinner skulls of children, which can result in higher RF exposure levels for children compared to adults.

Outdated Guidelines

The current SAR guidelines have not been updated since 1996 and may not reflect the latest scientific findings and understanding of the potential effects of RF exposure.

Body Separation Distances Not Practical

The body separation distances used in SAR testing are not practical for real-world use and assume that cell phones are not carried in pockets or other close proximity to the body.

Conclusion

In conclusion, while SAR values provide important information about the maximum possible RF energy absorption from a cell phone, they are limited in their ability to provide a complete picture of the actual RF exposure of a user. It is important to consider other factors, such as individual usage patterns and proximity of the cell phone to the head or body, as well as the potential health effects from RF exposure, when evaluating the potential RF exposure from a cell phone.

FAQs

What is SAR?

SAR stands for Specific Absorption Rate, which is a measure of the rate of radiofrequency (RF) energy absorption by the human body from cell phones.

Why is SAR important?

SAR values are used to demonstrate compliance with the Federal Communications Commission (FCC) guidelines and to ensure that the cell phone does not exceed the maximum permissible exposure levels set by the FCC.

What do SAR values indicate?

SAR values indicate the highest possible RF energy absorption for a user and ensure that the cell phone does not exceed the maximum levels of consumer RF exposure permitted by federal guidelines.

Can cell phones be compared based on SAR values?

No, cell phones cannot be reliably compared for their overall exposure characteristics based on a single SAR value.
