![]() A 2011 pooled analysis by Swedish researchers indicates a dose response that the risk of brain tumors (both glioma and astrocytoma) increased significantly for every 100 hr of cumulative exposure (Hardell et al, 2011). ![]() For example, the Interphone study one of the largest international study on cell phone use and brain tumors coordinated by the International Agency for Research on Cancer (IARC), shows no risk for general users (average 2 to 2.5 hours cell phone use a month) but a 40% increase in brain tumor glioma for “heavy” cell phone users – defined in the study as 1,640 hours or more cumulative cell phone use, or 30-minute daily use over a 10-year period of time (Interphone Report, 2010). The novel way in which Google Glass is used brings two unique risk concerns with regard to its radiation exposure.įirstly, scientific evidence indicates that cumulative exposure time plays a very important role in evaluating the health risks of wireless radiation. Unlike, cell phones which are used next to the head only when making phone calls, Google Glass is designed to be worn on the user’s head in the same position all day long. Google Glass represents a fundamentally new type of wireless device. In May 2011, the World Health Organization (WHO) classified radio-frequency electromagnetic radiation as “possibly carcinogenic to humans” based on increased risk of brain tumors. Although there is still no consensus on whether this type of radiation is harmful to human body, growing scientific evidence shows correlation between wireless radiation and adverse health effects, including but not limited to brain tumors, impaired brain function, sperm damage and behavioral problems in children. The prototype Google Glass has Wi-Fi and Bluetooth antennas but no cellular antenna. Like all wireless devices, Google Glass emits electromagnetic radiation, called non-ionizing radiation, in the radio-frequency (RF) range in operation. ![]() ![]() This article explores the implications of on-body wireless devices on radiation exposure. Though it is not yet on sale, some people have raised concerns that Google Glass introduces new types of radiation exposure risks due to the way in which it is worn. A wearable computer with head mounted display, Google Glass captures a lot of attention with its design, functions and life-style implication. Google Glass ushers in a new trend in wireless devices.
