EMF Monitoring, Measurement, Detection & Testing – Monitoring (measurement, detecting, and testing) the EMF radiation levels in your surroundings will allow you to understand it and then control it. without measurements, the understanding of EMF is very limited and narrow, and the exposure reduction becomes a guessing game. Without measurements, there will be no way to predict or monitor changes in the exposure levels.

EMF Monitoring, Measurement, Detection & Testing is the second step in handling EMF and its’ effects. Before trying to measure EMF, we recommend learning about EMF, at least knowing the main types of EMF (RF and ELF) their sources, and measuring units. EMF measurement will allow you to better reduce your exposure and use EMF protection in the best way.

Since Electromagnetic Radiant (EMF/EMR) can’t be seen and have no smell, you can’t touch it and even EHS (Electromagnetic Hypersensitive) people usually can’t feel it right away, measurement is usually the only way to know that it’s there, to record the levels, to find the sources and penetration points. Measuring EMF will allow us to improve our understanding of EMF, reduce exposure, find safety distances, and test that the protection we use is working.

EHS people are not an EMF meter

Electromagnetic Hyper Sensitive (EHS) people will feel EMF radiation in most cases, but usually, the symptoms will appear at some delay. Therefore EHS people are not EMF meters and also need to use an EMF meter as an objective method of measuring the radiation.

The Only way to “see” EMF

Without measurement, there is no deep understanding of EMF, and the chances for doing the right steps is lower. The only way to “see” Electromagnetic Radiation (EMR) or Electromagnetic Frequencies(EMF) Radiation is by measuring the levels of different types of EMF.

2 ways to measure EMF

Measuring EMF is possible by two methods:
1. Getting the help of a professional tester
2. DIY – ordering a fast EMF meter and doing the measurements yourself.

Professional measurements

If you chose option one, I suggest you make sure that the tester is not obligated to work according to the very high ICNIRP so-called safety standards and measurement protocols. If they follow the ICNIRP guidelines and protocols, it is possible that their meter will have a very slow sampling rate (very bad for RF) and for the outcomes of the test to be “all OK” with “very low” levels, and misleading in case you already holding the opining that EMF exposure is not healthy and/or suffering from EHS. Check with the professional tester, before ordering his service, that he is using fast EMF meters (high sampling rate, higher than 1000 per second), show and record peak levels (and not average), and give an informative report with level down to 0.00001 uW/m2. Also, ask him/her about his perception of the ICNIRP guidelines and the possible health risk.

DIY EMF Measurement

We believe that doing the measurement yourself, using a fast EMF meter, is the best way to improve your knowledge, to better understand EMF, find the sources, keep safety distances, find penetration points, and to see if your EMF protection really works.

We believe that DIY EMF testing is the best way to test the EMF levels in the house and to handle EMF problems before any damage is done.

We will emphasize again that in order to measure RF radiation in the best way, in order to find and identify RF sources (WIFI routers, smartphones, wireless laptops, and tablets) and penetration points you will need a fast (high sampling rate) RF Meter that samples the RF levels thousands of times every second.

A slow RF meter will not be able to “see” the low-duty-cycle signals from home and personal use RF sources such as smart meters, smartphones, tablets, laptops, WIFI routers, Bluetooth devices, and other wireless devices. A fast EMF meter is a basic “must-have” tool in the hand of every EHS person. A fast EMF meter can serve you for several years, for countless times and occasions, where and when there is a need.

We currently (2025) recommend the very simple to use ENV RD-100 or the numeric EMF meter the CORNET ED98QPRO5G.

Slow meters that show nothing

On the market today your can find even cheaper meters, usually from China, but they will not be suitable for home use, mainly because of the low sampling rate of 2-10 times per second (the same problem in some of the more professional meters that are built according to ICNIRP requirements).

As I noted before, measuring low duty cycle signals from WIFI routers, smartphones, tablets, laptops, and other wireless devices requires a very high sampling rate that these cheap china-made meters lack.

Accuracy, is it critical?

Well, obviously, accuracy is important but not critical. If the level of RF is 10mW/m2 and the meter shows 1mW/m2 , there is a problem. But if it showed 9.5 and not 10, or even 7 and not 10, I don’t think there is a problem there. As long as it shows the radiation (In RF meters, the ability to show the radiation is highly dependent on the speed at which the meter can measure it, the sampling rate. Which makes the sampling rate of the meter, in my opinion, the most important characteristic of a meter. and allows you to find the source or penetration point, the meter has done it’s job. Therefore, I believe that finding the sources and penetration points of the radiation is more important in EMF measurement than the accuracy of the measurement.

Discover EMF Sources

Today, in your house there could be many EMF/EMR sources, waiting to be discovered. These sources can emit dangerous levels of radiation, both on high (RF) and low frequencies (ELF), without you knowing about it. We think that measuring the levels of EMF/EMR in your house is an absolute must. We also recommend repeating the measurement several times, at different times and different days, in order to receive a good picture of the real radiation levels and to discover new sources of radiation within and from outside the house, once in a while.

In this section of the site, we will review methods and whys to measure EMF/EMR. We will review different meters that are available on the market. In addition, we will report about measurements we did (text, pictures, and videos).

Please note

It is important to remember that in front of a cell phone mast, or in other test environments there are sometimes many sources of EMF/EMR in different frequencies, and the meter can usually measure only the highest level but can’t measure or calculate all (read more about it in the Professional EMR tester page).
