What is an EMF?

What is EMF?

EMF, or electromagnetic field, is a type of energy that results from the movement of electrical charges. It can be found in various sources, including power lines, cell phones, and household appliances. EMFs can be further divided into two groups: non-ionizing and ionizing radiation. Non-ionizing radiation, which is considered less harmful, includes radio frequency fields, AC magnetic fields, AC electric fields and dirty electricity. Radio frequency fields are emitted by wireless technologies such as cell phones, Wi-Fi and Bluetooth, while AC magnetic fields are generated by the flow of electric current through power lines and household wiring and AC electric fields are created by the voltage on power lines and household wiring. Dirty electricity refers to electrical noise on the wiring of buildings. Ionizing radiation, on the other hand, encompasses types of radiation such as gamma radiation and x-rays.

What is a Radiofrequency Field?

Radio frequency fields (RF) are a type of non-ionizing radiation that are emitted by wireless technologies such as cell phones, Wi-Fi, and Bluetooth. These fields are used to transmit information at a frequency measured in hertz (Hz). The frequency range for radio frequency fields is typically between 3 kilohertz (kHz) and 300 gigahertz (GHz). There are concerns about potential health effects from prolonged exposure to radio frequency field. There are a lot of independent research articles indicating non-thermal health effects caused by RF. 

What is an AC Magnetic Field?

AC magnetic fields are also a type of non-ionizing radiation. They are emitted by the flow of electric current through power lines and household wiring. The strength of these fields is measured in gauss (G) or tesla (T). AC magnetic fields at typical levels found in homes and workplaces are generally considered to be low risk. However, some studies have suggested a possible link between prolonged exposure to high levels of AC magnetic fields and an increased risk of cancer.

What is an AC Electric Field?

AC electric fields are another type of non-ionizing radiation. They are created by the voltage on power lines and household wiring. The strength of these fields is measured in volts per meter (V/m). At typical levels found in homes and workplaces, AC electric fields are considered to be low risk. However, there is some evidence to suggest that prolonged exposure to high levels of AC electric fields may increase the risk of certain health effects or sensitisation.

What is Dirty Electricity?

Dirty electricity is a type of non-ionizing radiation that refers to electrical noise on the wiring of buildings. It is caused by the use of certain types of electrical devices and can result in high levels of electromagnetic pollution. Some studies have suggested that exposure to dirty electricity may be linked to certain health effects, such as cancer and diabetes. However, more research is needed to fully understand the potential risks associated with dirty electricity.

In conclusion, EMF is a type of energy that is emitted by the movement of electric charges and can be found in a wide variety of sources. EMFs are generally classified into two categories: non-ionizing and ionizing radiation. The non-ionizing radiation includes radio frequency fields, AC magnetic fields, AC electric fields and dirty electricity. While there are concerns about potential health effects from prolonged exposure to certain types of EMFs, at present, the scientific evidence for such effects is inconclusive and more research is needed to understand the potential risks.
