Ever wondered that nowadays 9 out of 10 people carry with themselves a device which emits harmful radiations which can lead to brain tumors , memory degradation, genotoxicity and even cancer??
Well that device is no nuke weapon or any other voodoo devices we see in any over the top science fiction movies but its our own dear old CELL PHONE .
Surprised?? you should be. Cell phones does emit harmful electromagnetic radiations and our exposure to such radiations is measured in SAR.
A cell phone's SAR, or its Specific Absorption Rate, is a measure of the amount of radio frequency (RF) energy absorbed by the body when using the handset. All cell phones emit RF energy and the SAR varies by handset model.
For a phone to receive FCC certification and be sold in the United States, its maximum SAR level must be less than 1.6 watts per kilogram. In Europe and India, the level is capped at 2 watts per kilogram, while Canada allows a maximum of 1.6 watts per kilogram.
Here are some of your favourite cell phones with their values.
Nokia phones have SAR values ranging from 0.6 to 1.3 W/kg
Samsung phones have SAR values ranging from 0.4 to 1.4 W/kg
Motorola phones have SAR values ranging from 0.8 to 1.5 W/kg
Blackberry phones have SAR values between 0.9 to 1.5 W/kg
HTC phones have SAR between 0.7 to 1.5 W/kg
So being a bit selective about your cell phones by taking a peek at their SAR values can save you.
Other precautions that must be taken are :
1. Headset - A headset is a cell phone accessory can significantly decrease radiation exposure to your brain. Not a bluetooth headset or a wireless headset - a headset that plugs into the phone. This eliminates cell phone radiation near your brain.
2. Speakerphone - Use speaker phone as often as possible. Speakerphone also reduces the cell phone radiation exposure you will experience because you do not have to keep the cell phone near you.
