Epidemiological Studies of Cancer and Occupational Exposure 
to Power-Frequency Fields also known as EMF (electromagnetic fields)

Field measurements: A number of studies have measured power-frequency fields in residences [C6, C7, C12,C18, C21, C30, C35, C36, C45, C46, C47, C59]. Both one-time (spot), peak, 24-hour and 48-hour average measurements have been made. Two of the studies [C47, C59] using measured fields have shown a statistically-significant relationship between exposure and childhood leukemia. No other types of cancer in either adults of children have been show to be associated with measured fields.

A report published in 2000 by Ahlbom et al [C54] calculated that if all the studies that included long-term measurements of magnetic fields were pooled, a statistically significant association could be found for children with 24-48 hr average exposures of 0.4 microT or greater. A second study published in 2000 by Greenland et al[C57] reported that if all the studies for that included estimated or measured magnetic fields were pooled, an association could be found for children with exposures of 0.3 microT or greater. A 2004 analysis by Greenland [C72] indicates that the association reported in 2000 is not statistically significant. No elevation of childhood leukemia was found in either analysis for children with average exposures below 0.3 microT.

A 2002 report [C64] found that measured electric fields had no significant association with overall childhood cancer or with any subtype of childhood cancer including leukemia, lymphoma or brain cancer.

Distance from lines: Many studies have used the distance from the power line to the residence as a measure of power-frequency fields [C4, C5, C9, C10, C13, C18, C20, C21, C33, C34, C53, C58, C74]. Four [C5, C18,C33, C74] of these studies have shown an association between distance from transmission lines and cancer rates. On particular note are:

·                     1993: A childhood cancer study [C18] reported an increase in leukemia incidence for residence within 50 m of high-voltage transmission lines.

·                     1997: An adult study [C33] reported an increase in leukemia incidence for residence within 100 m of high-voltage transmission lines.

·                     2000: A childhood cancer study [C58] found no association with any kind of cancer in children living within 50 m of power lines or substations.

·                     2005: A childhood cancer study [C74] reported an increase in leukemia incidence for birth addresses within 600 m of high-voltage transmission lines.

If there is a human health hazard from residential exposure to power-frequency fields it is highly unlikely to depend on anything as simple as the distance of the residence from the nearest powerline. Depending of the type of line and its current, magnetic fields from power lines become less than those produced by the typical residence at a distance of 20-70 meters (see figure below).

 What is known about "electrical occupations" and cancer rates?

Some studies have reported that people who work in some electrical occupations have higher than expected rates of some types of cancer. The original studies were only of leukemia. Some later studies also implicated brain, lymphoma and/or breast cancer. As with the residential studies, the associations found are weak, there are many negative studies, and there are no consistent dose-response relationships. Additionally, many these studies are based on job titles, not on measured exposures.

Meta-analysis [L9] of the occupational studies is even more difficult than for the residential studies. First, a variety of epidemiologic techniques are used, and studies using different techniques should not be combined. Second, a wide range of definitions of "electrical occupations" are used, and very few studies actually measured exposure. Lastly, there is little consensus as to the appropriate exposure metric. The following table summarizes the relative risks for the studies of occupational exposure.

16) Do laboratory studies indicate that power-frequency fields can cause cancer?

While the causes of specific cancers in individuals are still poorly understood, the mechanisms of carcinogenesis are sufficiently well understood that cellular and animal studies can provide information relevant to determining whether an agent causes or contributes to cancer [A2, A4, L13, L15]. Current research indicates that carcinogenesis is a multi-step process driven by a series of injuries to the genetic material of cells. Not surprisingly, this model of carcinogenesis is referred to as the multi-step carcinogenesis model.

What to do about EMF 

You should definitely listen to Camilla Rees, of Electromagnetic Health, interviewing Vicki Warren, the past executive director of the Institute for Bau Biology & Ecology. You'll learn how to lower your risk of EMF exposure around your house.  Warren discusses residual magnetism, static build-up, power charges (the field emitted by the wiring in your walls), power frequency magnetic fields, wireless communication electrosmog, and radioactivity and its by-product radon. She reveals how she examines a house for EMF dangers, and what you should avoid.
You're guaranteed to learn some things you didn't know, and improve your health, your sleep, and your life.
