Now that you know the top EMF detectors, let’s explore key information about EMFs and how to use a quality EMF meter to analyze electromagnetic field exposure in your environments.
What are Electromagnetic Fields (EMFs)?
Electromagnetic fields encompass both electric and magnetic waves that surround electrical devices. Power lines, electrical wiring, appliances, and electronic devices all generate EMFs both at extremely low frequencies (ELF) and at higher radio/microwave frequencies.
The electromagnetic spectrum is divided into different types of non-ionizing radiation based on frequency including:
- Extremely low-frequency fields (ELF) – Generated by power lines and electronic devices operating on 50-60 Hz electrical power. ELF magnetic fields are the main concern with dirty electricity.
- Radiofrequency fields (RF) – Generated by communication transmission including cell towers, cell phones, wifi routers, smart meters, etc. RF encompasses frequencies from 3 KHz to 300 GHz including 4G and 5G networks.
- Very low frequency (VLF) – Frequency ranges from 3 kHz to 3 MHz. Signals in this range travel hundreds of miles bouncing between Earth and the ionosphere. Natural sources include lightning while man made contributors are radio towers and transformers.
- Microwave frequency (MW) – Includes signals from 300 MHz to 300 GHz including 4G/5G cell networks, smart meters, and wifi routers.
Overexposure to EMFs at certain frequencies may cause health issues ranging from fatigue, trouble sleeping, and headaches to more serious concerns like increased cancer risk. Using an EMF detector allows you to analyze the non-ionizing radiation in your home and work environments.
Top 5 Reasons To Use An EMF Detector
Here are the main reasons for using an EMF meter to monitor electromagnetic fields:
- Check Common EMF Sources – Test devices like computers, large appliances, Bluetooth speakers, and electronics for high magnetic fields, electric fields, and dirty electricity. Also check smart meters, router EMF, substations, and power lines.
- Find EMF Hotspots – Scan an entire house or office to locate hotspots with elevated EMF exposures. Check bedrooms, office spaces, and areas where people spend considerable time.
- Measure 5G/Cell Tower Radiation – Use an RF meter to check for cell tower microwave transmissions indoors and outdoors including new 5G small cell sites. Useful for EHS (electromagnetic hypersensitivity).
- DIY Home EMF Remediation – Locating EMF hotspots allows you to install shields, filters and grounding to lower electromagnetic field levels. Check readings after changes to confirm reductions.
- EMF Litigation Evidence – Data recorded by EMF detectors has been used in court cases as evidence of excessive transmitter placements or emissions violations.
Using a quality EMF meter provides insight into invisible dangers allowing you to analyze the safety of spaces and make changes to reduce EMF exposure.
EMF Exposure Limits & Recommended Levels
Most government and health organizations release recommended maximum exposure levels for ELF magnetic fields, electric fields, and radio frequencies. However, some health experts argue that much lower levels are actually safe.
Here is a comparison of the most common EMF exposure limits:
ELF magnetic field limits tend to range from 2000 nT to 4000 nT depending on the country. Radiofrequency limits range from around 600-2,000 microwatts per square meter. Some health experts argue levels should not exceed 100 nT or 0.1 μW/m for ELF/RF
Since EMFs vary based on distance from the source, you must scan right at emission sources and then move further away to analyze the full field pattern. Compare measurements at different times of day as EMF levels fluctuate based on human activity and weather.
Also, pay attention to both average and peak measurements as certain equipment spikes during certain time intervals. And don’t forget to check multiple bands including ELF, RF, and microwaves for complete analysis.
How To Use An EMF Detector To Measure Radiation
Using an EMF meter properly ensures you obtain accurate data during testing. Follow this basic process when scanning for electromagnetic radiation:
- Select the frequency band you want to analyze – ELF, RF, or microwave
- Power on the EMF detector and allow it to zero/calibrate as needed per the instructions
- Slowly scan the sensor around the source or area in multiple directions
- Move closer and further away to map the full field pattern
- Note the peak levels and compare them to recommended limits or baseline averages
- Record data such as max readings, source type, and measurement times/places
- Repeat for all desired frequency ranges such as magnetic fields, electric fields, and radio frequencies
Tips when using an EMF detector:
- Move slowly during scanning and watch for spikes/drops – Stop to record peaks
- Check multiple sides/angles of sources for full analysis
- Be methodical during area scans to not miss hotspots
- Use max/peak hold functions to capture transients – Reset periodically
- Turn off other devices generating EMFs which may interfere
- Periodically zero out the sensor/recalibrate as needed
With practice, scanning for EMF hazards will become second nature. Just take your time, and be thorough in your measurements.
Now let’s take a closer look at key information on magnetic fields, electric fields, radio frequencies, and microwaves. Understanding the basics of these different EMF types will help you perform testing appropriately based on your meter specifications.
Magnetic Field Basics
Magnetic fields are areas of magnetism emitted by and surrounding electrical devices and wiring. Magnetic fields are generally the main concern with EMFs, particularly ELF magnetic fields from electrical current flowing through wires, circuits, appliances, and machines.
Most EMF experts recommend using a meter with AC magnetic field detection as this band causes most health issues. Many health experts argue that long-term exposure over 2 mG (0.2 μT) can be problematic.
Typical magnetic field levels:
- 2-20 mG – Typical background home/workplace
- 100+ mG – Near appliances, computers, and wiring (often brief exposures)
- 1,000+ mG – Very close to appliances and electrical devices
Common magnetic field sources:
- Power lines and transformers
- Electrical panels and wiring errors
- Wall sockets and switches
- Major appliances like refrigerators, washers/dryers and ovens
- Small appliances, computers, fans, chargers and other electronics
Magnetic fields drop off rapidly based on distance from the source providing the main emission control strategy. Maintain a 3-4+ feet distance from sources giving high mG readings for safer exposure levels.
Also, check electric devices for both when powered off and while operating to check for magnetic “dirty electricity” – These transient fields can penetrate walls throughout buildings.
Electric Field Basics
Electric fields derive from voltage and surround any electrically charged conductor such as power cords and wiring. Electric field strength varies based on the voltage level and drops off rapidly based on distance from the source.
Few EMF experts focus heavily on electric fields as most research implicates magnetic fields as the prime danger – However, quality EMF detectors often measure both.
Typical electric field levels:
- 10-50 V/m – Common background exposure
- 100-500 V/m – Near appliances/devices/wiring
- 1000+ V/m – Very close (< 1 foot) to operating electronics and appliances
Common electric field sources:
- Electrical wiring and cords
- Wall sockets and switches
- Televisions, computer monitors, and other electronics
- Large appliances and devices with transformers/converters or motors
Maintain a 1+ foot distance from electronics and ensure proper grounding to reduce electric field exposure similar to magnetic fields. Unlike magnetism, common building materials like wood and plaster provide effective electric field shielding as well as allowing containment.
Radio Frequency Radiation Basics
Radio frequencies encompass all electromagnetic radiation frequencies between 3 kHz to 300 GHz including microwave bands. Man-made RF radiation levels have increased exponentially in recent decades due to the expansion of wireless technology including:
- Cell networks – 2G, 3G, 4G & 5G towers
- Cell phones, tablets, and other mobile devices
- Wifi routers – WiFi, Bluetooth, DECT, Zigbee
- Smart appliances and smart utility meters
Radio frequencies induce internal electrical currents leading to cellular stress and inflammation. Many bioinitiative and health experts argue for much lower safety standards of 100 μW/m or lower.
Typical RF levels:
- 0.00001 – 0.5 μW/m2 – Natural background radiation
- 0.5 – 10 μW/m2 – Common urban background exposure
- 10 – 1,000 μW/m2+ – Close to cell towers, antennas, routers, smart meters, and devices
Control RF levels using distance from sources, additional shielding, and turning off wireless transmitting devices when not in use. Also, pay attention to neighbor’s signals crossing property lines indoors and outdoors.
Use a radio frequency (RF) meter specifically made for testing cell tower emissions, smart meter levels, and radiation from routers, smartphones, tablets, and other wireless-enabled devices.
Microwave Radiation Basics
Microwaves include radio frequencies ranging from about 300 MHz in the low microwave range up to 300 GHz at extremely high frequencies. Microwaves energize water molecules via dielectric heating leading to tissue damage at high exposures.
5G networks utilize new high band frequencies from 24 GHz to 90 GHz for faster data speeds. A microwave EMF meter specifically tuned for these wavelengths is important for analysis.
Typical microwave levels:
- 0.0001 μW/m2 – Natural background radiation
- 0.01 – 0.1 μW/m2 – Common outdoor/indoor background
- 1 – 100+ μW/m2 – Close to active microwave antennas and radar equipment
- 1000+ μW/m2 – Within operational microwave beam paths and dishes
5G small cell towers placed near homes and offices pose new microwave radiation threats from 24 GHz to 90 GHz beams for anyone nearby. Use a 5G meter specifically designed to check these levels.
Control microwave exposure by increasing distance from active emission equipment and using shielding like metal screens and specialized microwave-blocking materials.
Now that you understand the basics of EMFs and using a radiation detector, let’s explore methods for reducing high electromagnetic fields in your home and workplace environments.
