EMF Electric and Magnetic Field or, simply, electromagnetic radiation has, from time immemorial, been the major subject of research that has attracted the attention of many scholars. This, probably, maybe as a result of its effects on humanities. Despite our daily encounter or exposure to EMF, much is yet to be known about it by million users of electronic devices such as cell phones, television, wireless router, and other electrical appliances across the globe.
Obviously, most of us are enjoying the conveniences of modern lives made easy by modern technologies but very few know little or much about the radiation from them. Here, we have tried gathering a few information about EMF you need to know. Before unfolding the truth about EMF to you, it is very important to understand the term EMF for the sake of those who are yet to know or hear about EMF radiation upon experiencing it every day.
What is EMF:
Emf often referred to as radiation is electromagnetic energy that emits when charge particles change their velocities. It includes those radiations that emit from all electronic devices, electric power lines, and waves from suns. Unlike EMF sends out by the sun in the form of visible light,
Electric power lines, cell phones, microwaves, computers, WiFi routers, and other electrical appliances send out invisible energy waves that are worthy of being considered. Based on frequency, EMFs are typically group into ionizing and non-ionizing radiation you can check out EMF radiation Vs Ionizing radiation for more details.
Things You Must know About EMF Radiation.
Apart from knowing what EMF is, there are other lots of things one needs to about EMF like; the source of EMF, Classification of EMF, the effect of EMF on human health, EMF, and protection, and so on. We will briefly discuss each of these. See EMF Shielding: All You Need To Know. For more details.
SOURCES OF EMF.
Although they are invisible to the human eye, electromagnetic fields are everywhere electric and magnetic field exist. Electronic devices and electric power lines are not the only sources of EMF. There are other natural sources such as sun, atmosphere as in the case of lightning and thunderstorm. Earth has a magnetic field and since it is a good source of powerful positive and negative electric charges that apply forces on one another, it is also a very good source of EMF due to interactions of Earth’s magnetic and electric field.
Are All Electromagnetic Radiation The Same?
The major characteristics of the electromagnetic field are its wavelengths and frequencies. How the EMF interacts with different bodies within its reach depends largely on its frequency and wavelength just they are the bases upon which EMF radiation can be classified. There are low frequency, high frequency, ionizing, and non-ionizing EMF radiation.
The strength of each class of these radiations depends on their frequencies and wavelengths. The longer the wavelength, the lower the frequency while the shorter the wavelength, the longer the frequency. The EMF of higher frequency is often referred to as ionizing radiation while that of lower frequency is known as non-ionizing radiation.
Are EMF Radiation Really Harmful?
The harmfulness of EMF radiation depends on its type. For example, non-ionizing radiations which are mainly from our daily technologies like phones, computers, etc can potentially pose harm to our health over prolong exposure while ionizing radiations like X_ray, UV, gamma-ray are very harmful to human health. See 10 facts you need to know about ionizing radiation.
Can One Be Protected From Electromagnetic radiation?
The rising concerns of the harmful effect of radiation on our bodies have enforced a lot of people into an inquiry on how they can protect themselves from radiation. Obviously, our daily exposure to radiation is not that much to cause serious damage but it can result in some concerns if prolonged. The information from a Useful way to protect yourself from EMF radiation can guide you on how you can protect yourself from radiation. It will help you to know some precautions you can take to avoid much exposure to electromagnetic radiation.
The Danger level of EMF Radiation.
There are international guidelines on EMF exposure which are base on the finding of many years of scientific research. These guidelines are the guide to many industries producing electrical appliances. They test their products to ensure their EMF radiation falls within the ICNIRP’S guidelines before they are being sold. According to researchers, no known effect is expected if your exposure to EMF falls below the international guidelines.
A high level of exposure to EMF is very dangerous, it can cause neurological and physicological by disrupting human nerve functions. While it is unlikely that you can be exposed to such high-frequency radiation in your daily life, you should be aware that they exist. You need to be smart and careful about the high-level exposure to radiations like that of X-rays and sun.
