Highest Radiation Mobile phones launched

Over the last few years, several studies have found cellphones to increase the risk of brain cancer and dementia. However, most of such studies have remained largely inconclusive. Now to add fuel to the raging fire comes a World Health Organisation's study. According to WHO’s cancer experts, mobile phone users may be at increased risk from brain cancer and should use texting and free-hands devices to reduce exposure.

In India too, recently a government panel findings highlighted the health hazards of excessive mobile phone usage. The inter-ministerial committee named loss of memory, lack of concentration, digestive and sleep disturbances as some of the ill-effects caused by mobile phone radiation.

But, ever wondered which smartphones have higher radiation than others? CNET published a list of phones with high levels of RF radiation. The list includes some of the popular smartphone models from companies like LG, Motorola and Sony Ericsson.

The study is based on SAR or Specific Absorption Rate. SAR is a way to measure the amount of radio frequency (RF) energy absorbed by the body when using the handset.

Here are top 15 from the list.

Motorola Bravo

This Android-based phone tops the list of phones with highest level of radiation. Sporting a 3.7-inch WVGA display, Motorola Bravo has a 3 megapixel autofocus camera, 512 MB RAM, aGPS, accelerometer and Bluetooth.

The phone's Specific Absorption Rate (SAR) is 1.59
