San Francisco is the first city in the nation to require retailers of cell phones to prominently post the radiation exposure levels posed to consumers of cell phones. The cell phone “right to know” bill was passed by a strong majority, 9:1.
While no direct link between cell phone use and glioma or mengioma has been discoverd, research in over 13 countries has revealed “suggestions of an increased risk of glioma at the highest exposure levels.”
The ordinance requires that radiation levels be posted next to the pricing information for each model of cell phone sold in stores. The maximum radiation level allowed by the FCC also must be stated. The stated radiation level is called the “specific absorption rate,” and it refers to the amount of radiation absorbed by the body when the phone sends a signal to the network. The maximum SAR level set by the FCC is 1.6 watts per kilogram of body tissue.
According to the Environmental Working Group’s 2010 cell phone guide, the Sanyo Katana II gives off the least radiation, 0.55 w/kg. In comparison, the BlackBerry 8820, which gives off the most radiation, at 1.58 w/kg.
To minimize radiation exposure, the Environmental Working Group recommends using a headset, holding the phone away from the body while in use, limiting cell phone use by children and texting instead of talking.
