Check SAR Value to Find Mobile Phone Radiation

How to check SAR value of my mobile? Does my smartphone have the SAR tick?  The SAR value is an important indicator of the amount of radiation your mobile device is emitting and your body is absorbing! It is very important that you check SAR values of your mobile phone.

I recently bought a Nokia Lumia 720 and this sticker showed the SAR tick and I educated myself further about it. I had never seen this tick over my earlier cell phones…

What is SAR tick?

sar tickSAR Tick is an effort by the mobile manufacturers forum (MMF) to convey information to mobile phone users about compliance with radiation standards in their mobile device. As we are all aware that mobile phones emit radiation when they connect to the mobile tower nearest to them.

How safe are these mobile radiation to humans? What is the SAR value of your cell phone? Does your phone have a SAR tick?

What is SAR?

SAR stands for specific absorption rate and is a measure of the radio frequency power which is absorbed by the human body or head of the person using the wireless mobile device as it transmits the signal. Though the SAR values are tested at maximum power, in routine use the phone will be having much less SAR values. More technical information here.

When I read the small information booklet which came with the Nokia cell phone, it was good to know my Lumia was compliant with international SAR safety standards.

SAR guidelines

Governments worldwide have international guidelines on how much SAR values they allow. These guidelines vary from country to country. In the  United States,  the Federal Communications Commission (FCC) adopts an exposure limit of 1.6 W/kg (over 1g), while the  International Commission on Non-Ionizing Radiation Protection (ICNIRP) uses a limit of 2.0 W/kg averaged over 10g of tissue and is used across the world.

ALL cell phones must meet the FCC’s RF exposure standard, which is set at a level well below that at which laboratory testing indicates, and medical and biological experts generally agree, adverse health effects could occur.

Check SAR Value

Its is important to know if your mobile phone emits radio waves compliant with international guidelines. For more information related to SAR values, you can directly check with the mobile phone manufacturers, which publicly display this information on their websites. Here are some direct links.

Typically you need to enter the country, language and phone model on all these forms.

Reduce Phone Radiation Exposure

There might be health risks involved as suggested by WHO earlier, and worldwide health researchers are looking for links with brain cancers, though nothing is proved as yet.

While an increased risk of brain tumors is not established, the increasing use of mobile phones and the lack of data for mobile phone use over time periods longer than 15 years warrant further research of mobile phone use…

A recent Netherlands Health Council report states

Currently data is available for up to 13 year mobile phone usage. It shows no clear evidence that using a phone for such a time period results in an increased risk for brain tumours or other tumours in the head. Nothing can be said about any risks associated with longer use: for this we need studies running for a longer time.

Meanwhile, try to keep the phone away from your head  – use a hands-free Bluetooth devices to talk, use the speaker phone, talk less and SMS more … stay healthy.
