“Miscarriages and Computers- Kaiser Permanente study determined that women who worked more than 20 hours a week with VDU’s miscarried at a rate 80% higher than women who did the same work without VDU’s.”

“VDU’s and Fetuses- Animal studies in Sweden have found that EMF similar to that emitted by VDU’s caused malformation in fetuses.”

“Miscarriages Among Female Physical Therapists Who Report using Radio and Microwave-Frequency Radiation- Johns Hopkins University researchers report that physical therapists who are exposed to microwave (but not short-wave) diathermy units while pregnant, have an increased risk of miscarriage.”

“Occupation and Pregnancy Outcome- Low birth weight was associated with woman who operated electrical equipment as their occupation.”

“Perinatal Depression- Women who lived within 100 meters of power lines at 132kV and above experience a statistically higher incident of perinatal depression. Study was done in England using 11,292 women.”

                “EMF and Sex-Distribution of Offspring- Children born near a high voltage power station in Baghdad were                         87% girls, and 13% boys. Author suggests high female percentages might also be related to the same                                     percentages seen in offspring of lymphoma patients. Speculations are that EMF exposure interferes with                         calcium and this in turn affects the Y- bearing sperm (male) more than the x-bearing sperm motility.                                 Association Between Childhood Cancer and Magnetic Fields from Ground Current Sources- University of                         North Carolina researchers concluded the risk of cancer is increased among persons with increased                                     magnetic field exposures from residential ground currents (the currents flow through plumbing lines into                     the home from grounding conductors off power poles).”

“There have been many studies in the literature reported by a variety of investigators using a large number of different in vitro systems which have suggested that cellular signal transduction pathways are affected by EMF. This finding is quite expected since the signal transduction pathways receive both physical and biological information from other cells, as well as the environment, and transmit them in a cellularly appropriate fashion to produce the biochemical signals that regulate cellular functions. The electric field is attenuated within the cell but is amplified across the plasma membrane; therefore, in the absence of a clear indication that the magnetic field alone is responsible for all observed EMF effects, we must hypothesize that recognition and amplification of the information carried in the EMF signal is the domain of the plasma membrane and its signaling systems.”

“There is reasonable agreement as well on which early signaling pathways may be affected. The agreement, however, does not extend to a consensus regarding whether or not EMF effects at the in vivo level can be directly ascribed to any one pathway.”
