"Dr. Devra Davis on the complexity and erratic nature of cell phone signals. Our safety standards are based only on power density, not these other aspects she talks about like frequency, pulse etc."
In the last issue we explored the potential hazards of electromagnetic radiation from iPad use. We learned about warnings from the European parliaments and doctors' associations in various countries, and discussed the differences between pulsed digital wireless signals and continuous analogue radio waves. This time we are pleased to invite Dr. Joel Moskowitz to share his research findings regarding the health effects of cellphones.
I started studying the effects of cellphone radiation when Dr. Seung-Kwon Myung, a physician and epidemiologist from the National Cancer Center of South Korea, spent a year working in my center at UC Berkeley. He specializes in meta-analysis, a method by which data are combined across studies to generate more robust conclusions.

"Myelin is a fatty protective sheath that surrounds brain cells called neurons. Myelination is the process of acquiring this protection that takes place throughout childhood and adolescence and is not actually complete until the mid-20s and a little bit later in young males than females.
Low-powered but erratic pulses of microwave radiation from cell phones and other digital devices have been shown to interfere with myelin formation. This could increase the lifetime risk of developing neurodegenerative diseases such as Parkinson's and other problems such as hearing deficits and tinnitus – chronic ringing in the ears..."
PubMed - "Animals were exposed for 2 h a day for 60 days by using mobile phone (...). Result shows that microwave radiation emitted from 3G mobile phone significantly induced DNA strand breaks in brain. (...) Study shows that the oxidative stress is the main factor which activates a variety of cellular signal transduction pathways, among them the hsp27/p38MAPK is the pathway of principle stress response. Results conclude that 3G mobile phone radiations affect the brain function and cause several neurological disorders."
"In conclusion, the results of the present study show that prenatal EMF exposure results in altered electrophysiological properties of Purkinje neurons."
http://communities.washingtontimes.com - Technological development of wireless communication has brought an unprecedented increase in human, animal and plant exposure to microwave radiation.
Currently available biomedical research indicates that even at the low levels permitted by the safety standards, radiation exposures induce acute biological effects. The possible impact of the chronic exposures is not known beyond, at the most, the first 10-15 years. We do not have the faintest idea what will happen when exposures will last for a lifetime.
Experimental Oncology (full text beschikbaar als PDF)/ PubMed - In this review we discuss alarming epidemiological and experimental data on possible carcinogenic effects of long term exposure to low intensity microwave (MW) radiation. Recently, a number of reports revealed that under certain conditions the irradiation by low intensity MW can substantially induce cancer progression in humans and in animal models. The carcinogenic effect of MW irradiation is typically manifested after long term (up to 10 years and more) exposure. Nevertheless, even a year of operation of a powerful base transmitting station for mobile communication reportedly resulted in a dramatic increase of cancer incidence among population living nearby. In addition, model studies in rodents unveiled a significant increase in carcinogenesis after 17-24 months of MW exposure both in tumor-prone and intact animals.
The EMR Policy Institute - Author Martin Pall PhD writes:
One of the great puzzles about the action of electromagnetic fields is how can they influence the biology of our bodies? The reason that this is such a great puzzle is that these fields are comprised of low energy photons, with energies too low to influence the chemistry of our bodies. So how can they possibly influence our biology? Many have argued that the only thing that they can possibly do is to heat things, and yet it is very clear that levels of exposure that produce only the slightest heating have been repeatedly shown to produce substantial biological effects. Now this puzzle has been solved in a paper with the title of this email, published on line in the Journal of Cellular and Molecular Medicine, freely available on the publisher's web site:

"The cell viability of MW-exposed cells was decreased significantly. (...) The results of this study showed that 2.1 GHz W-CDMA modulated MW radiation-induced apoptotic cell death via the mitochondrial pathway"

Note: W-CDMA is a 3G cell phone carrier system used in the U.S. by Verizon and Sprint to handle data transmission. We have few studies on this type of modulation.
Effect of low level microwave radiation exposure on cognitive function and oxidative stress in rats
Use of wireless communicating devices is increasing at an exponential rate in present time and is raising serious concerns about possible adverse effects of microwave (MW) radiation emitted from these devices on human health. The present study aimed to evaluate the effects of 900 MHz MW radiation exposure on cognitive function and oxidative stress in blood of Fischer rats. Animals were divided into two groups (6 animals/group): Group I (MW-exposed) and Group II (Sham-exposed). Animals were subjected to MW exposure (Frequency 900 MHz; specific absorption rate 8.4738 x 10(-5) W/kg) in Gigahertz transverse electromagnetic cell (GTEM) for 30 days (2 h/day, 5 days/week). Subsequently, cognitive function and oxidative stress parameters were examined for each group. Results showed significant impairment in cognitive function and increase in oxidative stress, as evidenced by the increase in levels of MDA (a marker of lipid peroxidation) and protein carbonyl (a marker of protein oxidation) and unaltered GSH content in blood. Thus, the study demonstrated that low level MW radiation had significant effect on cognitive function and was also capable of leading to oxidative stress.
