2 Sal La Duca, BBEC, BSBA, CIEC, RFSO Environmental Assay Inc EMFs, The Hidden And Persistent Irritant (EMF = Electromagnetic Fields)

3 Acknowledgements I am deeply indebted and grateful to the U.S.A. for its Navy and its Applied Engineering And NASA for their Space Weather data

4 Like Air, we need EMFs to survive

5 Like Air, we need EMFs to survive But like Air, EMFs can have undesired qualities

6 Like Air, we need EMFs to survive But like Air, EMFs can have undesired qualities While touching very briefly on the desired qualities, I will elaborate on the undesired qualities

7 Electric Fields are produced by Voltage A Simple Capacitor

8 Electric Fields are produced by Voltage We live within a Planetary Electric Field that is necessary for life It can change with the weather A Simple Capacitor A Not-so-Simple Capacitor

9 Electric Fields are produced by Voltage We live within a Planetary Electric Field that is necessary for life It can change with the weather, and / or Solar interaction

10 Magnetic Fields are produced by Current Flow A Simple Coil

11 Magnetic Fields are produced by Current Flow We live within a Planetary Magnetic Field that is necessary for life A Simple Coil A Not-so-Simple Coil

12 Magnetic Fields are produced by Current Flow We live within a Planetary Magnetic Field that is necessary for life It can change with the weather, and / or Solar interaction

13 Summarizing... An Electric Field will exist between differently charged surfaces A Magnetic Field will surround the path of Current Flow

14 The Natural Fields aside, we make our own, and the greatest majority are Alternating Consider a typical neighborhood power line

15 And a slightly higher voltage one What s the difference?

16 And a slightly higher voltage one What s the difference? Clue: check Insulator sizes

17 The Electric Field Stress changes continuously in Intensity and Polarity. Above a certain level birds choose to stay away. Unhealthy?

18 <12,000V - E Field Stress

19 <12,000V - E Field Stress >300,000V - NO E Field Stress

20 In Perspective Content

21 Residential Electric Fields In about 80% of N American homes Content

22 Residential Electric Fields In about 80% of N American homes Relevant? Leukemia following Occupational Exposure to Content 60-Hz Electric and Magnetic Fields among Ontario Electric Utility Workers - Anthony B. Miller et.al (Dose-Response relationship with Electric Fields)

23 Residential Electric Fields In about 80% of N American homes Relevant? Leukemia following Occupational Exposure to Content 60-Hz Electric and Magnetic Fields among Ontario Electric Utility Workers - Anthony B. Miller et.al (Dose-Response relationship with Electric Fields) Historical Evidence that Residential Electrification Caused the Emergence of the Childhood Leukemia Peak - S. Milham, E. M. Ossiander 2001 (Children 2-4 yrs old)

24 Residential Electric Fields In about 80% of N American homes Relevant? Acceptable Risk? Leukemia following Occupational Exposure to Content 60-Hz Electric and Magnetic Fields among Ontario Electric Utility Workers - Anthony B. Miller et.al (Dose-Response relationship with Electric Fields) Historical Evidence that Residential Electrification Caused the Emergence of the Childhood Leukemia Peak - S. Milham, E. M. Ossiander 2001 (Children 2-4 yrs old)

25 Residential Magnetic Fields In about 40% of N American homes due to: 1) Power lines

26 Residential Magnetic Fields In about 40% of N American homes due to: 1) Power lines, 2) Plumbing Interconnections, and 3) Wiring Errors

27 Most structures are transparent to Magnetic fields Plumbing interconnections due to original (Edison s) design flaw (which causes Content house fires) Relevant?

28 Most structures are transparent to Magnetic fields Plumbing interconnections due to original (Edison s) design flaw (which causes Content house fires), or electrocution hazard when interconnected with plumbing Relevant?

29 Wiring errors mostly due to interconnecting return wires, and possible shock hazard - even to electricians

30 Most structures are transparent to Magnetic Fields Power line fields due to conductor separation Plumbing interconnections Content due to original (Edison s) design flaw and Parallel paths used as a bandage Wiring errors mostly due to interconnecting return wires, splitting return current over different paths

31 While the Earth Field is about 450 mg (milligauss), as little as 1% Alternating content appears to double the rate of Leukemia Relevant? Content A 1993 EPRI Study of 1000 homes: "The average spot measurement magnetic field exceeded 0.6 mg in 50 percent of residences, and exceeded 2.9 mg in 5 percent of the residences." So it would appear they are the Exception rather than the Rule

32 Content Linear Current Non-Linear Current Causes Harmonics Dark Blue: 120V Light Blue: Current

33 Content Harmonics

34 Harmonics Content Some Effects: Tinnitus, Seizures, Earthquake perception. The first does not stop if you put ear plugs in. The last two occur due to modulation.

35 Harmonics are the mystery ailment of electricity Some call it dirty electricity, to sell you something... There is No Content Human MPE (Maximum Permissible Exposure) They are produced by LED / Fluorescent lighting, Dimmers, ECM motors, and anything energy efficient or Digital

36 The most intense Harmonics are in the audio range, and are the same frequencies we are most sensitive to They can interfere Content directly with the cns (central nervous system) They can ride on ambient Electric or Magnetic Fields If intense enough they will spread far enough up the EM spectrum to produce / register as, genuine Radio Frequencies Armored / Shielded wiring eliminates about 98% of Electric and Harmonic field exposures

37 RF (Radio Frequencies) Shown are MPEs based on Thermal effects When using a cell Content phone by your head, you are at the MPEs, or above Nearby use can cause tumors, while distant use does not Tumors do not happen overnight, so long before they are detected, there is ongoing damage... Please have yours ready to use!

38 60 Hz Electric Field MPE 5000 V/m Earth s Field (DC mostly) 150 V/m Residential 60 Hz content: 1 to 10 V/m 60 Hz Magnetic Field MPE 9040 mg Earth s Field (DC mostly) 450 mg Residential 60 Hz content: < / = 0.6 mg Harmonics, No Human MPE, but 3% for any, or 5% of aggregates, for industrial users Residential content: varies with user choices RF MPE Frequency Variant Residential content: varies with user choices

39 Artificial EMFs have been around for only about 100 years Due to lack of knowledge, we now have embedded diseases Awareness can go a long way to avert ramifications You choose your level of action Beware of hucksters selling cures Much more at
