What effects radiation from cell phones have on users is a looming question with no definitive answers. How does your cell phone compare?
Recently researchers shared a study showing mobile phone use stimulates brain cell activity. The finding is vague, but there is an FCC imposed limit as to how much radiation a cell phone can emit.
Specific Absorption Rate (SAR) is the measure of the amount of radio frequency energy absorbed by the body when using a cell phone. The maximum SAR level allowed by the FCC is a SAR level of 1.6 watts per kilogram (1.6 W/kg). This level is usually found on the device on a label buried within the battery cover, but it should also be listed in the product documentation.
A federal agency based in Research Triangle Park is conducting a study to determine if cell-phone radiation causes cancer or other health hazards. The National Toxicology Program expects to finish the study in 2012 and present its findings by 2014. The program is part of the U.S. Department of Health and Human Services.
Scientists generally work from the premise that no amount of radiation is good. There are a number of common household items sources that emit what are considered to harmless levels of radiation including some TVs, computer monitors, smoke detectors, antique glassware & ceramics and even some foods. Our Sun emits radiation. Most of which is filtered by the Earth's atmosphere. So completely avoiding radiation may not be possible and while the radiation from your cell phone and other devices is not exactly a sought out feature, it may not necessarily be harmful.
Keep in mind these are microwaves which are less powerful than x-rays.
Users will have to decide whether or not caution should be exercised, but specialized cases, hands-free devices and even just simple moderation can reduce exposure.
Below you will find updated lists of the cell phones with the highest SAR levels and lowest SAR levels. For reference, since they do not appear in the lists, the iPhone SAR levels are .97 for the original EDGE model, 1.38 for the 3G, .79 for the 3GS, AT&T's iPhone 4 is rated at .1.17 SAR, and Verizon's iPhone at 1.18.
Here is a link to where you can check your device if it is not listed.
