Calculating SAR Value: A Quick Guide

In today's world, where smartphones are an integral part of our daily lives, concerns about the potential health risks associated with electromagnetic radiation have become more prevalent. One of the key metrics used to measure the amount of radiation emitted by a smartphone is the Specific Absorption Rate (SAR) value. Understanding how to calculate SAR values can help consumers make informed decisions when choosing a mobile device.

What is SAR?

SAR is a measure of the rate at which energy is absorbed by the human body when exposed to electromagnetic fields. It is typically expressed in watts per kilogram (W/kg) and is used to assess the potential health risks of mobile phones and other wireless devices.

How is SAR Calculated?

The SAR value of a smartphone is determined through a series of complex tests conducted in a laboratory setting. These tests involve placing the device in a simulated human head or body model and measuring the amount of radiation absorbed at various points. The results are then used to calculate the SAR value for the device.

Factors Affecting SAR Value

Several factors can influence the SAR value of a smartphone, including the frequency of the electromagnetic field, the distance between the device and the body, and the design of the device's antenna. Higher SAR values indicate that a device emits more radiation and may pose a greater risk to human health.

Interpreting SAR Values

In the United States, the Federal Communications Commission (FCC) sets limits on the maximum SAR values allowed for mobile devices. A SAR value below the FCC's limit is considered safe for human exposure. However, it is important to note that SAR values only measure the amount of radiation absorbed by the body and do not reflect the overall safety of a device.

How to Check SAR Values

Consumers can typically find the SAR value of a smartphone in the device's user manual or on the manufacturer's website. Some countries also require SAR values to be displayed on the packaging of mobile devices. Additionally, there are online databases where consumers can look up the SAR values of various devices for comparison.

Reducing Exposure to Radiation

While SAR values provide valuable information about the potential health risks of mobile devices, there are steps that consumers can take to reduce their exposure to radiation. These include using hands-free devices, keeping the phone away from the body when not in use, and limiting the amount of time spent on calls.


Understanding how to calculate SAR values and interpret them can empower consumers to make informed choices when selecting a mobile device. By being aware of the SAR values of different smartphones and taking steps to reduce exposure to radiation, individuals can minimize potential health risks associated with electromagnetic fields.
