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.

Long-term exposure to microwave radiation provokes cancer growth: evidences from radars and mobile communication systems

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.

Plausible mechanism of action for low-intensity EMR exposure - voltage-gated calcium channels

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


Abstract

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.

Abstract (PubMed)

 

The twenty-first century is marked with exponentially increasing development of technologies that provide wireless communications. To the pollution of the atmosphere with radio and TV signals, not only satellite communications but also any varieties of the Wi-Fi networks are added. By 2010 in the USA, 285 million mobile phone subscribers have been registered (for a little bit more than 300 million inhabitants). The estimate for the world is more than 5 billion mobile phone users at approximately 7 billion people living on this planet. Approximately 2 years ago, the International Agency of Research on Cancer (IARC) classified the electromagnetic fields used in mobile communication as a possible cancerogene. This paper discusses the potential health hazard and lack of scientific assessment and regulatory actions in protection of the life on the planet.

Review: Cell and cordless phone radiation probable human carcinogen

De Wereldgezondheidsorganisatie categoriseerde elektromagnetische straling van gsm's en andere draadloze apparaten als 'potentieel kankerverwekkend'. In een overzichtsstudie argumenteren verschillende wetenschappers nu dat er genoeg bewijzen zijn om deze straling te categoriseren als 'waarschijnlijk kankerverwekkend' en dat hersentumoren slechts de top van de ijsberg zijn.

Brain Diseases Affecting More People and Starting Earlier Than Ever Before

Science Daily - Professor Colin Pritchard's latest research published in journal Public Health has found that the sharp rise of dementia and other neurological deaths in people under 74 cannot be put down to the fact that we are living longer. The rise is because a higher proportion of old people are being affected by such conditions -- and what is really alarming, it is starting earlier and affecting people under 55 years.

 

Professor Pritchard of Bournemouth University says: "These statistics are about real people and families, and we need to recognise that there is an 'epidemic' that clearly is influenced by environmental and societal changes."
