cell phones: Microwave News Article Archive (2004 - )
“The results indicate that the current densities induced in the brain during DECT calls are likely to be an order of magnitude lower than those generated during GSM calls but over twice that during UMTS calls.” See also the group’s earlier paper.
“Our results suggest that certain aspects of cell phone use may negatively affect sperm quality in men by decreasing the semen volume, sperm concentration, or sperm count, thus impairing male fertility.” Click here for more on the growing literature detailing effects on fertility.
In August 2014, the Centers for Disease Control (CDC) issued and then rescinded precautionary advice on the use of cell phones. See our story, “CDC Calls for Caution on Cell Phones, Then Gets Cold Feet.”
Today,* Danny Hakim, an investigative reporter at the New York Times, has published a behind-the-scenes look at what was going on at the time, based on more than 500 pages of CDC internal documents, including e-mails, together with follow-up interviews. His story,...
The testes of rats exposed to 24hr of cell phone radiation (8hr in talk mode & 16hr in standby mode) for 20 days showed statistically signifcant changes in tissue structure. The authors caution against “unnecessary use of cell phones.” From Turkey. Open access.
“[T]his is the first study to demonstarte that 900 MHz EMF affected spatial memory in rats exposed to EMF for 28 days but not in rats exposed to EMFs for 14 days.” … Also “provides evidence that 900 MHz [EMFs] resulted in the disruption of BBB permeability…” From China’s 3rd Military Medical University in Chongqing.
“Students using mobile for > 2 hours/day may cause sleep deprivation and day sleepiness affecting cognitive and learning abilities of medical students.” Open access.
“Until proven otherwise, it is recommended that those with subfertility issues or seeking assisted reproduction minimize their exposure to environmental RF‐EMW radiation to alleviate its potential negative impact on sperm quality.” By Ashok Agarwal and Damayanthi Durairajanayagam of the Cleveland Clinic; open access.
“Headaches were reported significantly more often by the people who talked frequently and long in comparison with other users (63.2% of the subjects, p=0.0029), just like the symptoms of fatigue (45%, p=0.013).” Two years ago, members of the same Polish team published a similar study on mobile phone towers, with ambiguous results.
“The LF fields [<20 kHz] generated by mobile phone battery currents are, thus, not compliant with the ICNIRP reference levels for normal use, i.e., at the head.”
Based on four cases among women, aged 21 to 39. “[U]nlike the brain which is protected by the skull as well as a spatial distance from the cellular device, each patient here had direct contact between their device and their breast.” Open access paper from a team of California physicians. For a local TV news report featuring two of the authors of these case reports, click here. And here is the...
“Mobile Phone Radiation [MPR] Induces Mode-Dependent DNA Damage in a Mouse Spermatocyte-Derived Cell Line: a Protective Role of Melatonin,” International Journal of Radiation Biology, posted online August 19, 2013, from Chongqing, China.
“[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…”
“GSM 900 MHz Cellular Phone Radiation Can Either Stimulate or Depress Early Embryogenesis in Japanese Quails Depending on the Duration of Exposure,” International Journal of Radiation Biology, posted online April 10, 2013, from a group in the Ukraine.
“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.
by Poland's Stan Szmigielski, posted online by Electromagnetic Medicine and Biology, on January 15, 2013: "[S]o far, the published studies do not show that mobile phones can increase considerably the risk of cancer. This conclusion is backed up by the lack of a solid biological mechanism, and the fact that brain cancer rates are not going up significantly. However, all of the studies so far have weaknesses, which make it impossible to entirely rule out a risk."
Journal of Exposure Science and Environmental Epidemiology, posted online October 24, 2012. “This study demonstrates that personal RF-EMF exposure is affected by one’s own mobile phone in stand-by mode because of its regular location update.” From the University of Basel, Switzerland.

Times of India, August 15, 2012. The new limits will be 1/10th the current ones. Also, India will adopt an SAR standard for cell phones like that of the U.S. FCC —1.6 W/Kg, averaged over 1 g.
