No one can now imagine living without a smartphone since technology has become so ingrained in our daily lives. A smartphone with a poor SAR is the most dangerous even when not using it excessively, which can lead to health issues.
What is SAR Value?
The term SAR, which stands for specific absorption rate, describes how much radio frequency radiation is taken in by the body when using a mobile phone. The Federal Communications Commission (FCC) has established 1.6 watts per kilogram (1.6 W/kg) as the safe exposure level for radio frequency (RF) energy. Any smartphone with this SAR score or lower is considered “safe” to use.
There are a few techniques to determine the SAR value of your phone. You can decide which way is easy for you.
On a Website Where Many Mobile Phones’ SAR Values are Compiled
You may quickly find out your device’s SAR value by typing the name of your mobile phone model into a search engine, followed by a term like “SAR value.” You must have the grantee code and the product code of your mobile phone to check it on the FCC (Federal Communications Commission) website.
All devices have them, which can be found inside your phone’s case, though you might need to take out the battery pack to read the numbers. The codes are frequently placed on the back of mobile phones or in the user handbook, even if some don’t have a detachable battery pack. Visit the FCC website and follow the directions once you have this information.
On a Mobile Phone Manufacturer’s Website
On their websites, each manufacturer provides information regarding the safety of their products. It should be accessible in the support area or on a particular RF health subpage. The cell phone type or serial number is typically printed on a white label inside the device; therefore, if you are unsure of what model of mobile phone you have, you should remove the battery. The numbers will be printed in the user handbook if your battery is not detachable. Verify it on a trustworthy website, ideally the manufacturer’s website.
In the user Manual Guide of a Mobile Phone
User guides occasionally have information regarding SAR values so that you can look it up there. If you lost the manual that came with your device, you may quickly find it online and download it to your computer in PDF format. If you’re unsure where to look, enter the model number of your smartphone followed by the phrase “user manual PDF” into a search engine, and you should see the information you need. Every device should adhere to the global SAR measuring standard. Therefore, you’ll likely find enough details regarding your gadget’s compliance there.
In the Settings of a Mobile Phone
You can instantly access information about your device’s SAR value on your smartphone. You should be able to find it under “general” or “about phone” in the settings menu of your device. The type of mobile phone you own will determine this. For iPhones, for instance, you should select “Settings,” “General,” “Legal,” and “RF exposure.”
Dial a USSD Code
A USSD code, also called a “quick code,” is a mechanism GSM mobile phones use to interact with the service provider’s servers.
You may check the radiation level or SAR value of your smartphone by dialing a code like *#07#. You dial the number after entering the code on your phone’s keypad. The simplest way to check SAR value is in that manner, but not all devices support it. To avoid replacing your smartphone prematurely, it should show a SAR value of less than 1.6 watts per kilogram. It will help if you keep in mind that the figures vary depending on the country.
Additional Precautions
There are some more tips you should try to reduce your exposure. Try to avoid making calls if there is a weak signal. When inside a building, look for a better spot; the finest ones are near windows or outside. You should also limit the duration of your calls or, if you can, text instead. Using a headset when making calls is the easiest way to avoid radiation exposure.
Conclusion
The SAR value of a mobile phone should be as low as possible. Knowing your phone’s SAR value is crucial for responsible mobile phone usage. Since we are constantly exposed to radiation, it is preferable to select safer and healthier options.
