From Shivani Arjuna:
Regarding situations like the one you described at the Queensland Post Office [ message#480] that was next to an electrical substation, a crucial element is overlooked in the readings that are taken.
The readings focus on the strength of the magnetic fields. However, the FREQUENCIES present in the fields are of prime importance. I am sure these would have revealed much more relevant information if they had been checked.
The Russians have long been aware that frequency causes stress and disease, including cancer. Most of us who are deeply concerned about the health effects of EMF/EMR know this, yet for some reason the main focus in research and activism remains on field strength.
Please see http://www.lifeenergies.com/pollution/hemef/emfip1-11.htm for an oscilloscope image of the frequencies found in a classroom in a school where the present and previous teachers had gotten cancer, accompanied by the statement of Dr. Vitaly Reznik regarding the conditions caused by those frequencies.
My own Web site contains quite a bit of information about the improvement in various health conditions obtained when the damaging frequencies are removed from the living environment.
The Soviets and others have shown that frequency causes cancer and the many other conditions they list under the heading Radio Wave Sickness. It is not “magnetic field sickness.” It is frequency-caused. The harmful frequencies can be found in magnetic, as well as electric, fields, yes. However, removing the damaging frequencies results in health improvement even though field strength remains the same!
I am also speaking from personal experience when I say this. I suffered from painful and debilitating health symptoms, including extreme cardiac irregularities, that disappeared entirely after the offending frequencies were filtered from my home.
If the electric power companies in Queensland operate the way ones in the USA do, they are using the ground (terra firma) to return most of the current to the substations, and due to the “skin effect” high frequencies are subject to, that portion of the current returning via the ground is mostly high-frequency. Buildings near a substation, then, are in an area where the invisible rivers of high-frequency current are converging. As the Post Office is right next door to a substation, it would be very interesting to take ground current and frequency readings there.
Below is some information (from my Web site) about a second look at the famous Wertheimer study. This second look looked at the frequencies present, and found that it was frequency, not field strength, that correlated to the cancer.
Reported in Shocking News October 26, 2004:
[Indication that it was specifically the high frequencies that created leukemia in the famous Wertheimer study of 1979]
“Electrical engineers and epidemiologists re-examined the EMF-cancer hypothesis by measuring the current (amperes) at the utility neutral-to-ground wire at the transformer or pole near the homes, the amperage on water lines serving the homes, and the intensity of magnetic fields in the living areas most occupied by victims who had lived in the homes. BTD sampled 81 of the 579 cases (cancer) and control residences that were coded by Wertheimer and Leeper in 1979  and by Savitz et al. in 1988 [In ref. 11]. In this study 60 Hz, 180 Hz, and harmonic magnetic fields are associated with wire codes, but only 180 Hz and harmonic magnetic fields are associated with case/control status; case being a cancer victim lived at the residence.
The odds ratio (OR) combined across strata (HCC, LCC) for the 180 Hz and the sum of 3rd , 5th , and 7th harmonic fields were 4.0 and 4.3 respectively. Both were significantly elevated above the null value of 1 ( P = 0.0061) for either field components. The odds ratios iindicate cancer deaths were four times more likely among victims who lived in homes with high levels of 180Hz current or the 3rd , 5th and 7th harmonics than among controls with similar socioeconomic backgrounds. The conclusions reached 25 years earlier  were validated, but an improved measurement instrument with coil censor signal analyzer (HP Model 3561A) implicated harmonic currents which earlier test meters did not detect.
[180 Hz is a 3rd harmonic frequency that becomes an additive on 3-phase wiring. This means that once on the wiring it keeps adding its higher harmonics, up and up into higher frequencies.]
