Technology has now become an integral part of our daily lives. Wherever we are, there are electronic devices scattered around. We may not even know how many devices we come in contact with every day. These electronic devices, however, emit electromagnetic radiation. There are many disadvantages to being exposed to high levels of radiation over a long period of time.
It is important to know how much radiation a device emits. And in this case a metric called SAR Value is widely used.
What is the SAR value of the phone?
Specific Absorption Rate is abbreviated as SAR Value, which refers to the rate at which the amount of Radio Frequency (RF) energy absorption received by our body from a source. The SAR Value provides an easy way to measure the characteristics of the radio frequency exposure of a wireless device following the Safety Guidelines formulated by the FCC.
As the use of wireless devices and technology continues to grow, it is important for everyone to know about SAR Value. The purpose of this post is to give you a simple idea about SAR Value. This is not a technical or health related article. We look forward to further updates after this post. It is learned that the phones currently available in the market by the recognized manufacturers are being manufactured in compliance with the safety guidelines of SAR.
Advantages / disadvantages of SAR Value
Electromagnetic frequency emitted from a device by SAR Value refers to the amount of energy received by our body. Electromagnetic frequencies are being used in devices to improve technology. Phones are using this radio frequency energy to connect to the network. So if it is not the phones can not be connected to the network. Again, if the SAR is too high, it can cause various kinds of damage to our body. That is to say, technology is both a blessing and a curse for us, as can be seen from the discussion of this SAR value.
The process of checking the SAR Value of any mobile phone is quite simple. If you go to the phone dialer or phone app and dial * # 07 #, you will see more important information besides SAR Value. According to the American standard, the limit of SAR value of a mobile phone is a maximum of 1.8 watts per kg (when tested through 1 gram of human tissue). On the other hand, according to European standards, when they test 10 grams of human tissue with a sample, the SAR value limit is a maximum of 2 watts per kg.
It is understood that the maximum SAR limit allowed will be 1.6 or 2.0 watts / kg (depending on the US or EU standard). Less than that is better. But now you will find this standard phone in the market. These are the highest SAR values of the devices. Usually the SAR value of the phone is less than the maximum amount. However, it is better to keep the mobile phone away from direct contact with your body.
For devices that cannot be checked for SAR Value in the manner specified, visit the product page on the official website of the device manufacturer to find out the SAR Value of the device. You will also find SAR Value in the About / About Phone section from the settings of many phones. Besides, you can easily know the SAR value of any phone by visiting the smartphone listing website, GSMArena.com.
The SAR Value of a device exceeds the safe limit, but it is best to avoid using or coming in contact with that device. Currently, the incidence of diseases caused by electromagnetic radiation has increased worldwide. Therefore, any device that emits more radiation than the safety limit should not be used.
However, there is no special reason to think about this. You can get technical information from the official page of FCC (US official site). Because most of the electronic devices are made in strict rules. So there is no reason to worry about the radiation of a well-known device used in daily life.
