Biological EMF-Safe Homes
Wellness begins with understanding the principles of life. Electromagnetic magnetic fields, water, and light — the “invisible fields” — are essential to life. In this section I go through the various electromagnetic fields that make up our living and work spaces. All information in this section is adapted from the WHO and studies by independent research bodies. Guidelines are from The International Institute for Building-Biology® & Ecology.
The earth and all living pulsate with electromagnetic energy. It is the basis of how life functions.
Manmade electromagnetic fields (EMFs) were introduced into our environment with the invention of modern electricity. These electric and magnetic fields are part of the electromagnetic spectrum which extends from static electric and magnetic fields, through radiofrequency and infrared radiation, to X-rays. All populations are now exposed to varying degrees of EMF, and the levels will continue to increase as technology advances.
These artificial EMFs have completely different intensities, pulsing patterns, and wave forms, that don’t exist in nature. In an age of wireless technology and mobile phones, much of the attention in the media has been on "wifi radiation", or high frequency radiation. It is probably the greatest technological leap in the past 100 years — and it’s changed the EMF landscape. However, there are other types of EMFs in our environment.
Anything that uses electricity creates an electric field. Electrical fields are created by voltage, or the potential difference in charge between two points in an electrical field. It exists even when there is no current flowing, i.e. when your television or lights are not turned on for use. Higher voltages create stronger electric fields. Electrical fields tend to attract to the human body.
Magnetic fields are created by the flow of an electric current. The intensity or strength of the magnetic field is directly related to the power consumption of the device. These fields usually remain close to their source, but can travel a few hundred metres, such as in the case of high voltage power lines.
Dirty electricity (DE) is the frequencies that travel on your home wiring from things like solar power inverters, fluorescent lighting, dimmer switches and wireless “smart” meters.
Radio Frequencies / Microwaves
As electric fields and magnetic fields approach higher frequencies, they become airborne and become radio waves. Everyday sources of radiofrequency electromagnetic fields are radio and television broadcasts, radar, satellite navigation, broadcasting antennas, and microwave ovens. These airborne waves can travel a huge distance.
EMFs and health
Typically EMFs are classified as ionising and non-ionising radiation. In the former, X-ray and gamma-rays consists of photons with sufficient energy to break molecular bonds. Non-ionising radiation do not have this ability and thus had been long thought of as “harmless”. But while they do not have the strength to break apart bonds, non-ionising radiation have biological impact on the body.
Testing your home for EMFs
Electromagnetic field testing is an intriguing science; it requires a good understanding of electrical principles, the ability to identify and quantify various EMFs that impact the environment using technical equipment, an understanding of how the building materials in a home may affect exposure to radiofrequencies, as well as a good understanding of how shielding solutions impact the environment.
