Modern technologies we use daily can provide wonderful tools to enhance our lives. However, they emit electromagnetic radiation that can penetrate and affect us, disturbing our environments and putting our health at risk. Our environments have dramatically changed over the last decade. We are exposed to electromagnetic radiation 100 million times more than our grandparents were, and our exposure grows each year.
What is electromagnetic radiation (EMR)?
Electromagnetic radiation is essentially the result of electromagnetic field (EMF). Which can be described as a series of electrically charged waves of force that oscillate at a particular frequency and have a certain distance between one wave and the next one.
Natural sources of electromagnetic fields
Electromagnetic fields are present everywhere in our environment but are invisible to the human eye. Electric fields are produced by the local build-up of electric charges in the atmosphere associated with thunderstorms. The earth's magnetic field causes a compass needle to orient in a North-South direction and is used by birds and fish for navigation.
We are all electromagnetic beings
Our bodies can be as easily penetrated as air by electromagnetic fields. This means if you are near a powerful EMF, electromagnetic radiation isn’t just around you, it’s inside you. Human beings are bioelectrical systems. Our hearts and brains are regulated by internal bioelectrical signals. An environmental exposures to artificial EMFs can interfere and disturb the fundamental biological processes in the human body.
There is 4 major kinds of EMF: Electric fields, Magnetic fields, Dirty Electricity and Radio Frequency.
AC Magnetic Fields
Magnetic fields are created by alternating electrical current flowing in conductors. Typical sources are power lines, building wiring, transformers, motors and appliances. They are low frequency typically running at 60Hz here in USA. This type of radiation will come as much as 6 feet into the living space. High magnetic fields can pose significant EMF health risks. Errors in the building’s wiring system, improper grounding, power lines stray currents that can travel on water and gas line are a significant source of elevated magnetic fields. These wiring flaws are also electrical code violations and should be eliminated. Magnetic fields are typically measured in milliGauss (mG) or microTelsa (uT) .
What is dirty electricity?
Dirty electricity is a form of electromagnetic pollution also called high frequency voltage transients and can be present on power lines and building wiring where only standard 60Hz electricity should be. Dirty electricity can interfere with the proper functioning of appliances and electronic equipment, a phenomenon known as electromagnetic interference. It is fast-growing source of electro-pollution in homes, schools, and businesses today.
Common sources include: light dimmer switches, fluorescent light bulbs, electronic devices, appliances, overhead power lines, smart utility meters, stray current on water and gas lines.
Radio frequency (RF) and Microwave Radiation
Radio frequencies allow for the effective transmission of information through the air, and are the basis for our wireless telecommunications and information systems. These high frequencies are used for AM and FM satellite radio, smart utility meters, television, radar, cell towers, cell phones, cordless phones, Bluetooth, wireless computer and data networks and baby monitors. The use of wireless technologies has exponentially increased over the last decade and has become a significant source of microwave radiation for occupants in the buildings. The strength of the field is often expressed as power density in microWatts per square meter (uW/m2).
