A smartphone is considered safe to use if it has a SAR rating below 0.5. SAR stands for specific absorption rate and is a measure of the amount of radio frequency energy absorbed by the human body when the phone is used. It can vary based on the type of antenna and the location of the phone.
Several government regulatory bodies regulate the SAR of a cell phone. The FCC, Environmental Protection Agency, and the Food and Drug Administration work together to set the legal limits for a device. The SAR value is intended to notify consumers that the phone does not exceed the maximum permitted exposure levels. However, it is also important to remember that SAR is not an accurate measure of the actual amount of radiation that you might be absorbing. Moreover, some SAR values may be very high and can pose health risks to users.
The FCC, in partnership with the Environmental Protection Agency, works to develop better guidelines for smartphone usage. To do this, it requires cell phone manufacturers obtain a SAR rating for their devices. Once the manufacturer has received the required SAR rating, the device is listed on the FCC’s database. In addition, it is also required that the manufacturer publish this information on their website.
Getting a SAR value is not difficult. Typically, you will find the value in the user manual or in the box. Alternatively, you can use a search engine and type in the name of the device plus “SAR value” to find the best value. You may also find a SAR value on the IMEI sticker on your device. If your device is dual SIM, the SAR value will vary between the two SIM cards. The SAR value of a device will also change based on the country in which the device is made.
In the U.S., the SAR value for a device can range from 0.01 to 1.6 watts per kilogram. In the European Union, the SAR value is a little less, at 2.0 mW/g. Similarly, it is not always advisable to buy a phone with a SAR value that is above 1.6 mW/kg. While this may sound like a lot, it has nothing to do with the actual amount of radiation that you might be exposed to.
If you are looking to purchase a new smartphone, it is in your best interest to find out the SAR value of your current model. This way, you can make an informed decision on whether or not to buy the phone. The SAR of your smartphone may fluctuate during normal use, but it should always be within the acceptable range. There are plenty of choices, but your best bet is to buy a reputable brand.
You can check the SAR of your mobile phone by using the USSD code *#07#. This code is a protocol that GSM cellular phones use to communicate with the service provider’s computers. After you have entered the code, the results should display a SAR value below 2.0 watts per kilogram. It is also possible to find the SAR of your current mobile phone on the phone’s settings. In addition, you may wish to consult the user manual, which can be found on the internet.
