A study released in 2012 in Oxidative Medicine and Cellular Longevity confirms that cell phone radiation can damage cells and kill cells by generating reactive oxygen species, which are the same things that we believe are the cause for many cancers.
Yao-Sheng Lu from Jinan University in Guangzhou, China and colleagues conducted a test and see how damaging the radiation of 900 MHz radiofrequency electromagnetic field (RFEMF) is. The radiofrequency is used for cell phones.
For the study, human peripheral blood mononuclear cells (PBMC) were exposed to the radiofrequency at a specific absorption rate (SAR) of ~0.4 W/kg for longer than two hours.
The researchers found the radiofrequency activated reactive oxygen species (ROS) and caspase-3 in the mitochondrial pathway and decreasing the mitochondrial potential, causing apoptosis or programmed cell deaths. The radio-frequency triggered the activation of ROS by disturbing the conformation of lipids, protein and DNA, the authors reported.
The authors say ''Although human PBMC was found to have a self-protection mechanism of releasing carotenoid in response to oxidative stress to lessen the further increase of ROS, the imbalance between the antioxidant defenses and ROS formation still results in an increase of cell death with the exposure time and can cause about 37% human PBMC death in eight hours.''
Reactive oxygen species are believed to be responsible for many types of cancer. Long term exposure to cell phone radiofrequency has been linked to increased risk of brain cancer in studies that included those who used cell phones for more than 10 years. (JD)
