10 Cellphones with highest radiation

Do cellphones cause brain cancer, dementia or have other side effects? Though there have been numerous studies on this, the verdict remains unclear. For, some studies reveal long-term side effects of cellphone usage, others term them as mere hype.

However, it is largely certain that cellphones do emit radiation. In fact, some analysts are now of the view that all cellphones should compulsorily display their radiation levels. US-based environmental group EWG recently published a list of phones with high levels of RF radiation. The list, which appeared on CNET, includes some of the most popular smartphone models from companies like LG, Motorola, Blackberry and Samsung.

The study is based on SAR or Specific Absorption Rate. SAR according to the Cellular Telecommunications Industry Association is "a way of measuring the quantity of radio frequency (RF) energy that is absorbed by the body."

Here's over to the 10 mobile phones with highest radiation.
