“[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.

“Relationship Between Exposure to ELF EMFs and Breast Cancer Risk: A Meta-Analysis,” European Journal of Gynecological Oncology, Vol.35, pp.264-269, 2014.

“[Our analysis] indicated that, for the premenopausal group, the occurrence of breast cancer may be related to exposure to ELF-EMFs, but for the menopausal group it has no relationship. The specific mechanism still requires further study. … It is suggested that premenopausal female should minimize exposure to ELF-EMFs.” From China.

“Our studies also emphasize that many more studies are urgently required to address the potentially hazardous effects of RF-EMF exposure on brain development.” From a Chinese military lab in Chongqing.

“Response in Animals Exposed to Non-Ionizing RF Fields: Some Underlying Mechanisms,” International Journal of Environmental Research and Public Health, posted April 22, 2014.

“The observations in the studies reviewed … suggested that RF exposure was beneficial and able to provide resistance in animals and human cells to the damage induced by subsequent exposure to sub-lethal and lethal doses of ionizing radiation and chemical mutage.” From China, open access.

“Association Between Mobile Phone Use and Semen Quality: A Systematic Review and Meta-Analysis,” Andrology, posted online April 3, 2014.

“[A]lthough the defined effect of mobile phone use on semen quality cannot be concluded from the existing studies, men should not keep mobile phone in their trousers pockets or near testicles to avoid the potential harmful effect of RF radiation on the male reproductive system.” From the 3rd Military University in Chongqing, China.

Five years ago we reported on what we thought was an important clue in the search for understanding the well-documented association between childhood leukemia and EMF exposure. A team based in Shanghai presented evidence that children carrying a genetic variation linked to DNA repair were four times more likely to develop leukemia than those without that genetic marker. We called the finding a “major breakthrough” and predicted, “It simply cannot be ignored.”

We were wrong. So wrong.

What happened next —or rather, what did not happen— sheds light on why EMF research treads water and never moves forward.

“Magnetic Fields Exposure and Childhood Leukemia Risk: A Meta-Analysis Based on 11,699 Cases and 13,194 Controls,” Leukemia Research, posted online, January 2, 2014.

More support for an association for exposures above 0.2 μT (2 mG) —from a group in China. See also the accompanying editorial which finds that this potential risk factor “deserves our attention.”

“EMF Exposure and Male Breast Cancer Risk: A Meta-Analysis of 18 Studies,” Asian Pacific Journal of Cancer Prevention, 2013; from Jing-Wen Sun and coworkers in Wuhan, China.

“The results suggest that EMF exposure may be associated with the increase risk of male breast cancer…” (open access).

“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…”

“Different EMF Waveforms Have Different Effects on Proliferation, Differentiation and Mineralization of Osteoblasts in Vitro,” Bioelectromag-netics, posted online June 17, 2013.

“[S]inusoidal EMFs inhibit osteoblast proliferation while square EMFs promote osteoblast proliferation. While the square and serrated EMFs have no appreciable effects on osteogenesis, triangular and sinusoidal EMFs enhance the osteogenic differentiation and mineralization of osteoblasts, with triangular EMFs being the most potent waveform.” Based on 50 Hz exposures at 1.8 mT (18 G) —from Lanzhou, China.

There are many reasons not to use a cell phone in an elevator. The most obvious would be as a courtesy to other passengers. Another is that a phone has to work harder in a shielded space. It's forced to operate at higher power levels for the signal to get out and reach the nearest tower and that leads to more ambient radiation in the elevator.

What most cell phone users would never consider is that a fellow passenger absorbs some of the radiation that would otherwise bounce back off the walls. It turns out, according to some new calculations from Japan, that a lone user can get a maximum exposure of about 1.6 W/Kg, 80% of the ICNIRP standard (2 W/Kg). But be advised that exposures could exceed the current U.S. FCC standard by a wide margin, under worst-case conditions. (This is a rare —no, unique— example of an American EMF standard being stricter than those in other countries.) The FCC limit is averaged over only 1g of tissue and, as Jim Lin, a member of ICNIRP, has often pointed out, increasing the averaging volume from 1 g to 10 g could triple the allowable radiation exposure (see MWN, N/D00, p.3). These new findings appear in the May issue of the IEEE Transactions on Microwave Theory and Techniques.
