How much should be SAR value is safe? Information about SAR (specific absorption rate) values and safety is becoming increasingly important as cell phone and wireless devices become more widespread. Understanding the science behind SAR ratings and the recommended safe limits can help consumers make informed decisions about the technology they use.
The Specific Absorption Rate (SAR) is a measure of how much radiation is absorbed into the body when using a device such as a mobile phone. Knowing the SAR value of a device is important, as it can help us to determine how safe it is to use. In this article, we will discuss the optimal SAR value to ensure maximum safety when using a device, and the potential risks of using devices with higher values.
What is SAR?
SAR is the amount of radio frequency (RF) energy absorbed by the body when using a device. The SAR value is measured in watts per kilogram (W/kg). Devices must meet the SAR limit set by the Federal Communications Commission (FCC) in order to be sold in the US.
How Much SAR is Safe?
The FCC has set the SAR limit at 1.6 W/kg for devices used in close proximity to the body. This is the maximum level to ensure safe use of the device. However, many devices have SAR values much lower than this, often as low as 0.2 W/kg.
The Risks of Higher SAR Values
Using a device with a higher SAR value can result in more radiation being absorbed by the body. This can lead to an increased risk of developing cancer or other health problems, such as headaches or fatigue. Therefore, it is important to check the SAR value of any device before using it, and to make sure that it does not exceed the recommended limit.
In conclusion, the optimal SAR value for safe use of a device is 1.6 W/kg. It is important to check the SAR value of any device before using it, to ensure that it does not exceed this limit. Using a device with a higher SAR value can lead to an increased risk of developing cancer or other health problems, so it is important to be aware of the potential risks.
