Environmental organization claims health threat
Apple's latest iPhone, the 3GS, ranks almost squarely in the middle of smartphones in terms of radiation output, a non-profit activist organization says. The Environmental Working Group notes that according to compiled data, the 3GS produces approximately 1.19W/kg of radiation. The figure is substantially lower than the worst-case examples, the T-Mobile myTouch 3G and the Kyocera Jax S1300, which each produce 1.55W/kg.
The 3GS still produces considerably more output than phones towards the bottom of the scale, such as the Samsung Impression and BlackBerry Storm, which are rated at 0.35 and 0.57W/kg respectively. It also emits more than the 0.97W/kg of the original iPhone, but less than the iPhone 3G, rated at 1.39W/kg. The three best-performing phones on the list, such as the Nokia 9300i, are no longer being sold.
In a new report, the EWG claims that people using cellphones for 10 years or more could develop "serious health problems." Because of radiation, the report suggests, cellphone users have an "increased risk of developing brain and salivary gland tumors, neurological symptoms such as migraine and vertigo, and neurodevelopmental effects observed as behavioral problems in young children." Though the impact of phones is questioned, the EWG is pushing for the US government to require displaying radiation levels at points of sale.
