The World Health Organization (WHO) classifies cell phone radiation as a “possible human carcinogen” due to an increased risk of brain cancer from long-term and heavy use of cell phones. Although short-term cell phone exposure has not been shown to cause brain tumors, research is showing that it can change your brain activity in ways we don’t fully understand yet.
Human brain cells communicate via electrical impulses, which can be detected by non-invasive EEG (Electroencephalogram) measurements. A recent mobile phone study by researchers from Netherlands found that when a dialing mobile phone is placed on the ear, its radiation, although not consciously sensed, is electrically detected by the brain. In the study, 31 healthy females were exposed to a 3G mobile phone for 15 minutes and their EEG activity was measured. Changed brain activity (i.e. cortical reactivity increase) was detected immediately after radiation peaks, which are produced during the phone’s normal dialing process.
The Netherlands study is not the first one to show an EEG change as a result of acute exposure to cell phone radiation. In 2015 a French study showed that the brain EEG pattern (alpha band) is altered by GSM cell phone radiation; a 2013 Italian mobile phone study also demonstrated significant changes in brain activity (i.e. cortical excitability) induced by 45-min exposure to GSM mobile phone; a 2013 Australian study showed altered brain EEG (alpha band) by GSM-like RF radiation. A 2011 Australian study showed an effect of acute 2G and 3G exposure on human cognitive functions. A 2010 U.S. study found that pulsed radiation from ordinary mobile phone use can trigger human brain evoked potentials (Eps) as detected by EEG.
Positron emission tomography (PET) imaging is another tool used to study the effect of cell phone radiation on human brain activity. Using PET scans, a 2011 U.S. study published in the prestigious Journal of the American Medical Association (JAMA) demonstrated that 50 minutes of cell phone use changed human brain glucose metabolism in the region of brain closest to the phone antenna. A 2006 Finland study also showed that mobile phone radiation induced changes in cerebral blood flow in humans.
The evidence from above studies shows that the human brain is sensitive to cell phone radiation. The observed brain activity change cannot be explained by only a heating (or thermal) effect as a result of temperature rise from energy absorption. However, no underlying biological mechanism has been identified to explain the effects. We also don’t know what health consequence may be resulted from such repeated stimulations. More research is still needed to understand the mechanism and long-term health effects of cell phone radiation on humans. The current safety standard did not take into account any non-thermal effects, such as evidenced in the above studies. As of today there is no known safe level of exposure to cell phone radiation.
Here at Pong, we feel it is important to be aware that our brains are sensitive to cell phone radiation and long-term exposure can cause possible adverse health effects such as brain cancer. The best thing you can do now is to take a proactive stance to reduce your exposure to cell phone radiation. There are ways to reduce your exposure to mobile phone radiation. For some easy steps please refer to our article on tips to reduce mobile phone radiation exposure. We think one of the best ways to limit your exposure is to use a radiation reduction phone case from Pong.
