EMF & RF levels drastically vary in spaces. To test levels in the room and the effectiveness of the garments, obtain an RF meter, these are available at a number of locations and are usually simple to operate. We prefer to use TENMARS TN-195 Meter because this meter is specifically used to indicate electromagnetic pollution generated artificially. Wherever there is a voltage or a current, electric(E) and magnetic(H) fields arise. All types of radio broadcasting and TV transmitters produce electromagnetic fields, and they also arise in industry, business, and the home, where they affect us even if our sense organs perceive nothing. 

 

Introduction 

     Electromagnetic Field (EMF) is a zone of moving electrical charges. We are constantly exposed to EMF radiations in our everyday life; they are emitted from almost every electronic device such as microwave oven, cellphones, WiFi routers, wireless devices, etc. The radiations are harmful to our health when they exceed a threshold point. Electromagnetic Emissions influence our metabolic processes. Moreover, these harmful radiations have different biological effects on cells through various mechanisms. There are two different types of electromagnetic waves, i.e., low frequency and high frequency. They affect the human body in different ways. The issue with EMF is that the radiation is not visible to the naked eye since the field is invisible. However, there are a variety of methods for determining the amounts of EMF emissions in our environment. We'll go over a few of them in this article.

Units of EMF

     EMF is measured in terms of volts/meter (V/m). EMF will be 1 V/m when a one-volt electric potential is one meter away. EMF is also measured in kilovolts/meter (kV/m). 

The Importance of Measuring Electromagnetic Radiation

     According to the National Council for Radiation Protection, a consistent exposure that is greater than 10V/m is hazardous to human health. Prolonged exposure to EMF radiation can cause serious health concerns in the human body, such as headache, palpitations, chest pain, nausea, tiredness and fatigue, dizziness, irritability, insomnia, and so on. To keep ourselves safe from the EMF radiations. It is important to keep a track of emission levels. If you are walking around your home, not close to electronic devices such as computers or TV, you will get an EMF reading of between 1-5V/m. Different electronic devices emit different levels of EMF radiations when we express EMF in milliGauss. A typical TV set emits 25-500mG at 1 inch and 1 foot it is somewhere around 0.4-20mG. (6)

Ways to measure the levels of Electromagnetic Field (EMF) emission...

     The EMF levels in your home or office can be measured with the help of an EMF meter. This portable device can measure the level of radiation with satisfactory accuracy. The value of EMF is location-dependent. The intensity of an electromagnetic field is inversely proportional to the distance between the source and the receiver. The Electromagnetic field becomes weaker as you get further away from the source. 

 

emf and rf measuring device

The intensity of the electromagnetic field is measured in watts per square meter (W/m2). The rate of power flow in an electromagnetic field is measured through the basic relationship, i.e., W(Watt)=V(Volts) X A (Ampere). Furthermore, the energy density of an electromagnetic field is proportional to the square of the amplitude of the electric (or magnetic) field. For electromagnetic waves, the intensity can be expressed as Iave=cϵ0E202, whereas the Iave is the average intensity in W/m2. The intensity of EMF is directly proportional to the number of electronic devices. When an area has a greater number of electronic appliances, the induced electromagnetic field becomes stronger. The speed of the electric current is determined by the voltage potential; the greater the potential difference, the faster the electrons will travel. (2)

The Federal Communications Commission (FCC), which regulates mobile phones, has set a radiation threshold of 1.6 watts per kilogram averaged across 1 gram of tissue for cell phones. However, most cell phones surpassed that limit by 2 millimeters or the space between your phone and your pocket.  (1) Although in 2021, the Children’s Health Defense won a landmark lawsuit against the FCC for inadequate protection guidelines for EMF exposure due to widespread EMF sickness. The FCC is now required to revise the guidelines within the year. 

In short, we can conclude that it is very essential to have a device that can measure the intensity of the electromagnetic field to keep ourselves safe from higher levels of EMF radiation. 

When you are in areas of uncontrollably high EMF levels, Silver Affect garments made with pure Silver metal are perfect for protecting the most vulnerable body parts.
