In the U.S. no personal wireless device can have a SAR that exceeds 1.6 W/kg. The SAR standard, however, was developed several decades ago in the U.S. primarily by physicists and engineers to protect users from the acute effects of the heat generated by microwave radiation. The standards do not protect users from the non-thermal effects of cell phone radiation which have been associated with increased brain cancer risk among long-term cell phone users and other health problems in the short term including electrosensitivity, sperm damage and infertility, and reproductive health risks in children.
Just because these devices are legal does not mean they are safe
Although many health researchers, including myself, have questioned the utility of assessing only a device’s SAR, currently that is all governments measure and regulate. Governments want consumers to believe that all legally marketed wireless devices are safe, and that the SAR level does not matter as long as it meets the legal standard. Yet no study has proved that exposure to low-intensity microwave radiation is safe, and thousands of peer-reviewed, published studies have found biologic effects from such exposures. The research suggests that governments need to adopt more stringent, biologically-
Medical and public health professionals should call on Google to end this experiment on Glass users or at least fully inform consumers of the potential long-term health risks from wearing this device.
