If a survey omits one EMF source-point or one frequency band, then you did not receive a complete EMF inspection. - James Finn, EMRS
Elexana LLC conducts AEMC Certified Soil Resistivity/Ground Resistance Testing per NFPA/NEC requirements.
This is what you should expect from a full-panel home assessment:
Elexana’s Residential EMF Survey CHECKLIST
Stray Current can enter your building via water, gas, and coaxial internet service lines or your HVAC system. It is measured in amperes and flux density. Be sure your consultant can provide solutions compliant with the National Electric Code, NEC.
Complete Grounding System assessment check and measuring in mV, amperes, and fundamental frequencies on each, often they are not 60 Hertz. This check is for two tests: the EGC Equipment Ground Conductor System and the Overload Lightning Protection System. Singular to Elexana LLC, we measure your grounding system's impedance to ensure that it is < 25 Ohms.
(We can also conduct a soil resistivity test with a state-of-the-art 4-point ground rod Wenner Test and calculate how many ground rods you require to reach the NEC requirement of < 25 Ω, upon request.)
AC Magnetic Fields to 30 MHz, indoors and outdoors, must be measured. Most measure to 1 MHz at best, but we include the magnetic fields from HF High-Frequency sources. The spectrum range between 1 - 30 MHz is the most overlooked bandwidth because the equipment to measure this bandwidth correctly is so expensive. This may be why this ubiquitous field is not discussed much but should be included in every assessment. We identify and isolate the size, shape, coupled frequency bands, velocity, and all co-signaling fields. We identify source points and propose the best solutions. Many of these sources can be remediated. AC Magnetic emissions from your appliances and other source points, such as power lines, electrical conduits, risers, and heating panels need to be measured. If your work requires power tools, then your tools need to be measured. Your consultant must be trained and qualified to identify wiring errors and provide instructions to your electrician on how to fix them.
Airborne AC Electric Fields to 60 MHz, measured in Volts-per-meter, V/m. This includes all E-fields emitted by ungrounded lamps and appliances, Romex (unshielded home electrical wiring), and poorly grounded electrical distribution lines. Tip: sometimes, powering OFF a bedroom will increase the E-Field flux within a room, so please do not do this unless it is verified as safe.
DC Magnetic Fields, measured in nanoTesla (nT) with a state-of-the-art DC magnetometer used for scientific research. Geomagnetic stress can be a severe issue at specific locations and should not be overlooked.
DC Electrostatic Fields, measured for source-point identification. (We measure this in V/m for commercial interference applications and surface voltage for those with pacemakers and/or heart conditions.) Be sure to receive a solution plan. A DC static shock can cause serious harm.
Epidermal Voltage, measured at the workstations and sleeping areas to help determine and remediate source points. Much of this work is often done during an assessment. We measure our epidermal voltage as a reference. Clients can opt to have their voltage measured too.
Electromagnetic Interference, EMI, often incorrectly termed Dirty Electricity (DE) measured on the phase, neutral, and ground using an oscilloscope amplitude and FFT. Also, measuring airborne EMI is essential. (To only use a plug-in Broadband EMI Line Meter to sell wall outlet filters is an overdone sales tactic to ramp up commissions.) We use state-of-the-art equipment to accurately and thoroughly assess the harmonic transients coupled to your electrical system’s 60 Hertz sine wave.
Radio Frequencies for the 5G Network, At Elexana, we can measure RF analyzed in 3-D with a 100% POI (Percentage of Intercept) spectrum analyzer using units: dBm, Watts, Voltage, and Amperage from frequencies as low as 9kHz to determine and isolate source points directionality.
Note: The consultant should consider much more than power density levels: the number of signals and frequency clusters, reflection rate, phase distortions, signal coherence, multi-path interference, and more. Only measuring peak levels does NOT tell the whole story for providing the best RF solutions. Peak levels from a hand-held meter are almost always incorrect.
Baseline Testing of all Ambient Fields: A full and final conclusive EMF assessment of all emissions entering the home from outdoors or the surrounding apartments versus what is produced within the home. Make sure the consultant provides clear solutions. Simply recommending that you get some distance from a source point is not a professional solution.
This graphic above is data logging from the rear border of a rural property in Westchester nearest to a 23 kV power line. We walked a straight line perpendicular from the power line up to the front of the property and continued to the road out front. Notice that the entire property was in the green color. This is the “no-concern” range for a trained EMRS. This test is just one in a series of AC Magnetic Field tests we run for a property.
Prospective New Home Purchase Survey Checklist
A. If your concern is a power station, an electrical transmission line, a sub-station, or a transformer nearby the property:
1. We simply do more. We have years of experience, knowledge, and training from the Institute of Building Biology’s Advanced Electromagnetic Radiation Program.
We measure AC Magnetic Fields with our certified-calibrated gaussmeter to provide a thorough and professional assessment of the property. We can then calculate daily and seasonal emissions.
Power Transmission Lines emit ELF (Extremely Low-Frequency Radiation) @ 60 Hertz. The nature of this energy enables us to measure this frequency range as two separate fields; magnetic and electric fields.
2. Power lines can cause stray currents to run through the ground. We insert electrodes into the Earth to measure these currents and the corresponding ground resistance, ohms-meters. We do this with state-of-the-art Electrical Engineering tools.
4. If we have access to the basement of your prospective new home, we can check for stray current entering into the home, too.
5. We provide a baseline examination to quickly determine if you have magnetic fields caused by electrical wiring errors.
6. We will then present to you a hierarchy of solutions if required. Often, this allows you to receive credit from the bid or justify a reduced offer.
B. If your concerns are the nearby cell tower transmitters, airport radar, or neighbor’s smart meter and WiFi:
1. We test airborne electric fields from 60 Hertz all the way up to the 5G network.
2. We measure the power flux density and the frequency of these signals. You can watch the action of your neighbor’s smart meter or the nearby cellphone tower.
3. We will then share with you the best mitigation strategies for your situation.
C. If you are concerned about Geomagnetic Stress resulting in strong DC magnetic fields in the Earth:
1. We test the DC Magnetic Fields with a state-of-the-art certified-calibrated DC Magnetometer used for scientific laboratory work.
2. We’ll advise you on the best location to build your new home. This testing will also help to avoid rebar and other metallic structures from becoming magnetized or to create potential stress fractures to the home’s concrete foundation.
D. If you need any or all of these services, then please just let us know. We are happy to answer any of your questions.

✅ Clarification: An EMRS surveys electromagnetic fields and consults with your engineers, electricians, and contractors when there is an electromagnetic interference issue requiring a specific mitigation plan, operation, or application. Unless an EMRS is also an electrician, an EMRS does not perform electrical services. An EMRS is trained to guide your electrician in completing the required corrections; however, your locally licensed electricians can only provide all electrical services.
✅ Disclaimer: All of our residential EMF testing and electrical system tests and measurements are non-invasive. We do not remove electrical panel covers, junction box covers, or outlet receptacle cover plates. The conducting of our specific tests and measurements does NOT require licensing, only the proper training and certifications we have acquired. Any objectionable findings that require reporting to your local power company are fully backed, verified, and supported by Einstein Electrical Corporation, our licensed partner. Only our affiliate-licensed electricians will provide electrical repair and installation services.
✅ Clarification: There is no state licensing offered by any state in the USA for residential EMF Testing, dowsing, Feng Shui, or any other practices related to testing the energies at your residence once granted your permission to do so. Any person claiming to hold a state license violates fair business principles and ethics and possibly breaks the law. If he/she insists that there is a state license for EMF Testing and that they have this license, please ask that it be emailed as a PDF photocopy for you to send to us, your local chamber of commerce, and your local county courthouse.
✅ Clarification: Although we feel strongly that actionable levels of electromagnetic radiation exposure pose serious health and safety issues, we do our best to defer all health-related questions and concerns to our affiliate licensed medical professionals. All “medical experts” should be licensed physicians or licensed chiropractors.
