A Report on Non-Ionizing Radiation

Last January, a team led by Yawei Zhang of the Yale School of Public Health in New Haven published an epidemiological study on the possible link between thyroid cancer and cell phones. Though some “suggestive” associations were seen among long-term users, none was statistically significant. Still, the results “warrant further investigation,” they advised.

Zhang did follow up, and what she found could well change the way people think about cell phone cancer risks.

She discovered that some people have an innate susceptibility to thyroid cancer when exposed to cell phone radiation. These individuals have small variations in their DNA which affect the functioning of seven different genes.

All seven genes regulate DNA repair.

Very low SARs lead to DNA breaks: 0.09 W/Kg @900 MHz and 0.169 W/Kg @1.8 GHz. Damage “more pronounced” at 1800 MHz. (Allium cepa = onion)

In summary, our evidence supports the hypothesis that sustained whole-body RF-EME is capable of inducing a state of oxidative stress in the male germ line, a cell vulnerable to the effects of ROS. … Furthermore, our data further implicate the mitochondria as the target for RF-EME biophysical interaction, with a consequential elevation of mitochondrial ROS generation being linked to reduced motility and elevated oxidative DNA damage and DNA fragmentation in the spermatozoa of exposed male.” From Australia.

From the NTP: "[S]ignificant increases in the levels of DNA damage measured by the comet assay were seen in several tissues from rats and mice, indicating that RFR may be capable of causing increases in DNA damage.” More here and here.

The U.S. National Toxicology Program (NTP) will soon embark on a new phase of its long-running RF project. Last year, the NTP concluded that RF radiation causes cancer; now it will begin a systematic search for mechanisms to explain how and why the tumors developed. Work is expected to begin by the end of the year.

The research plan is wide-ranging. It will include studies on gene expression, oxidative stress and DNA damage and repair, as well as on the possible role played by heat. Other priorities on the NTP agenda are studies on behavior and stress.

The National Toxicology Program (NTP) has changed course and will not —at least for the time being— publish its findings of increased DNA breaks among rats exposed to cell phone radiation as a stand-alone paper.

The DNA study, which is part of NTP’s landmark experiment showing that RF radiation can lead to tumors in the brains and hearts of laboratory animals, will now be incorporated in NTP’s Technical Report on the $25 million project, the NTP has told Microwave News.

“Induced oxidative stress causes DNA damage in germ cells, which alters cell cycle progression leading to low sperm count in mice.” These changes are reversible (from Assam University, India; open access).

In May, the U.S. National Toxicology Program (NTP) announced that male rats exposed to cell phone radiation developed higher rates of cancer. Soon, the NTP will explain how that might have happened.

The same RF/microwave radiation that led male rats to develop brain tumors also caused DNA breaks in their brains. Female rats —which did not have significant elevated tumor counts— had fewer DNA breaks.

All these findings are part of the same $25 million NTP project.

The NTP results provide “strong evidence for the genotoxicity of cell phone radiation,” Ron Melnick told Microwave News.

“Our main finding was the increased oxidative DNA damage to brain after 10 days of exposure with the decreased oxidative DNA damage following 40 days of exposure compared to their control groups.” This is yet another research paper from Turkey.

“[H]ands-free devices might reduce the MPR exposure intensity to the human head. However … the male reproductive system may be put into risks. Thus, it is important and urgent to establish feasible and effective strategies to prevent reproductive impairment following daily exposure to MPR. Significantly increased levels of DNA damage in the “dialing” and “dialed” modes were found in the present study…”

“In conclusion, two independent attempts failed to reproduce genotoxic effects of RF-EMF in HL-60 cells as reported by the REFLEX project. These repeat experiments were performed under the same experimental conditions as the original experiments and one part of the repeat study was performed by the scientists who also generated the REFLEX data.”

“Taken together, this suggests that the low intensity radiation emitted by a commercial GSM 900 MHz cell phone can result in either decrease of DNA strand breaks; or otherwise induce substantial DNA damage in cells of the developing bird embryo depending on the duration of the exposure. See also the group's earlier paper in Electromagnetic Biology and Medicine.

“Our study shows that exploratory activity, which is associated with physiological increases in neuronal activity and the encoding of new information, causes widespread increases in neuronal DSBs.”

We haven't posted many new items recently because we've been too busy fixing up the new Web site. In the process, we've been rereading many of our old stories. Last night, we came across an item from five years ago under the title "Cell Specific Responses to RF." It highlighted some new research from Finland, which found that cell phone radiation affected the activity of ODC, a biologically important enzyme, in...

Next Sunday, the New York Times Magazine will feature a long piece titled "Do Cell Phones Cause Brain Cancer?" by Siddhartha Mukherjee (it's already on the Times' Web site). It's a well-written article, as might be expected by his well-received book, Emperor of All Maladies: A Biography of Cancer. Yet an important part of the story is missing: the politics of cell...

If you want to see just how misguided the ICNIRP enterprise really is, take a look at its new EMF exposure guidelines in the December issue of Health Physics. [See also our November 10 post.]

Start at the end with the footnote that discloses the composition of its five-member ELF Task Group (p.830...

It's the strongest warning yet. John Aitken, a well-known fertility researcher, is advising men who want to have children not to keep active mobile phones below their waists. This issue, he says, "deserves our immediate attention."
