Powerlines

Measure Fields from Powerlines

Power lines

All powerlines emit magnetic fields and the closer the powerline is to the home or workplace, the higher the field will be.

Magnetic fields pass through the earth, so locating powerlines underground does not block the fields they emit.

In two decades of testing fields in homes, we’ve found that many homes are located near underground powerlines and most homeowners don’t know that they’re there.

Many studies have shown that being exposed to magnetic fields above 4 milliGauss (mG) increased the risk of childhood leukemia and the International Agency for Research on Cancer has classified these fields as Class 2B carcinogens, in the same category as lead.

A study by Dr Malka Halgamuge and Lyn McLean found that fields of 4 mG and more are present in many homes. MORE details here.

Many authorities worldwide, including Australia’s Energy Networks Association, have adopted policies of ‘prudent avoidance’ or ‘precaution’ to reduce exposure.

[Studies]Taken in conjunction they suggest that relatively heavy average exposures of 0.4 µT [4 milliGauss (mG)] or more are associated with a doubling of the risk of leukaemia in children under 15 years of age

Magnetic fields increase: 

  • childhood leukemia
  • adult leukemia
  • brain tumours
  • neurodegenerative diseases
  • oxidative stress (free radical damage) that is found in many health problems and contributes to ageing
  • depression

Measuring fields from powerlines

The meter we recommend for measuring fields from an overhead or underground powerline is the FW Bell 4180 magnetic field meter (gaussmeter).

Buying a new home?

It’s important to find out what magnetic fields are affecting your home before you buy, as not all magnetic fields can be reduced or shielded afterwards.

You can either purchase or hire our FW Bell 4180 magnetic field meter.

Warning

Be sure to use only products that can be demonstrated to work. Some companies make claims that their products protect against electromagnetic radiation or ‘harmonise’ radiation, however their products are not tested to demonstrate they are effective in reducing exposure and we’ve often measured the same exposures with and without harmonising devices in place.

We advise only using products that can be demonstrated to work to give you the peace of mind that you’re actually being protected.

You can see the test reports demonstrating the effectiveness of our products on this website. 

I’m interested in more information. Please sign me up to the EMR newsletter so that I can find out about the latest research.
