Kaiser Permanente researchers have published several studies linking pregnant women’s exposure to electromagnetic fields to increased miscarriage as well as increased ADHDobesity  and asthma in their children.

In 2001, the World Health Organization’s International Agency for the Research on Cancer  classified ELF magnetic fields as “possibly carcinogenic to humans” based on the consistent research finding a two-fold increase in childhood leukemia associated with residential exposure to magnetic fields. The research finding effects has increased since that date. (Read the research studies here.) 

Over a dozen countries already have some level of protective policy in place regarding this type of electromagnetic radiation. The countries of Croatia, Finland, France, Israel, Italy, Netherlands, Norway, Slovenia, Switzerland, Germany, Spain, Belgium (Wallonia, Flanders) Denmark, Liechtenstein, Luxemburg, Lithuania, Poland have a magnetic field radiation limit for  “sensitive areas” far far lower than ICNIRP.  Sensitive areas are generally defined as areas where children live and play such as schools, kindergartens or recreation areas. Sometimes the definition includes hospitals and residential areas. These countries’ magnetic field EMF limits are 3 or 4 milligauss, the level of milligauss associated with childhood leukemia in repeated published studies. However ICNIRP recommends a residential magnetic field exposure limit of 2,000 milligauss (mG) and an occupational exposure limit of 10,000 mG.

The United States has no limit on legal levels of milligauss electromagnetic radiation. However the California Department of Education enacted a regulation to  require minimum distances between new schools and the edge of a transmission line “right-of-way.”

2020 research investigating ELF-EMF levels in schools has found exposure at students’ seat positions was mostly caused by electrical appliances, electronic wiring, and distribution boxes and the authors conclude that, “it is important to design safe and appropriate environments for digital learning in schools, such as proper seating arrangements, to avoid ELF-MFs exposure to students as much as possible.”

Reducing Exposure to ELF-EMF in Your Home

ELF-EMF fields from electronics and appliances fall off rapidly with distance. Experts are less concerned about the brief exposures to ELF-EMF we encounter everyday but far more concerned about longer-term chronic exposures, including at night while we sleep. Here are some ways to reduce your daily exposure:

  • Do not rest a laptop or electric on your lap. Keep electronics on a table.
  • Do not sleep near a charging cell phone or a charging laptop or digital device. Always charge devices away from sleeping/living  spaces and preferable during the daytime. Charging generates high EMFs near the cord and batteries can catch fire during charging.
  • Do not use a cell phone while it is charging as the ELF-EMF field is high. Likewise, try to use your laptop on battery rather than while charging. Always unplug the laptop once it is charged.
  • Corded alarm clocks and radios can have intense EMFs, so replace your alarm clock with a battery powered alarm clock. This will reduce your exposure at night.
  • Do not sleep with your head or body near a wall that has the electric panel, electric meter or appliance on the other side.
  • Unplug appliances and electronics such as TV’s and microwaves ovens when not in use. This reduces ELF and also reduces energy consumption. An easy way to do this for electronics is to get a powerstrip that you can easily switch off.
  • Remove electronics from the bedroom—especially around your bed and the crib.
  • Avoid sleeping with electric blankets and heating pads; if you use an electric blanket to preheat your bed, unplug it before sleeping. If you only turn it off, the EMF will still be present.
  • Do not stand near a microwave oven when it is on. Better yet, use a toaster oven.
  • EMFs from electrical wiring can be reduced if you flip the switch on the breaker for the electrical circuits near the bedroom at night. However circuits are not designed to be flipped every night.  Some people use a “kill switch” so all you have to do is flip one switch at night to turn off breakers all at once.
  • Get a magnetic field meter to take measurements in your home. If your ELF measurements show high levels in your home, it could be faulty wiring which an electrician can fix. Often simple fixes can greatly reduce ELF-EMF exposure.
  • Take measurements in your home if you live near powerlines because levels can be high throughout the house from the EMF emanating from high voltage powerlines.
