Residential EMF Testing Checklist: What to expect…

We've provided a checklist to ensure that you receive a professional EMF/EMR survey of your home.
Elexana is the only company in America measuring EMF, Electromagnetic Field Radiation, from DC-60 GHz (beyond IoT and 5G to satellite transmissions and automobile guidance systems) using ISO 17025 certified-calibrated equipment to ensure accuracy and sound data for making our recommendations and producing official legal documents and reports.
Suppose your report does not include up-to-date ISO 17025 calibration certificates of the testing instruments used by your technical consultant. In that case, it is likely not a professional assessment that would hold up under a court of law.
If an EMF survey fails to consider all point-sources and frequency bands, then unfortunately you will not receive a complete EMF inspection and could remain exposured to potentially harmful levels of electromagnetic radiation.
(Please, see the checklist of services we provide, below.)

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 with an oscilloscope and flux density with a magnetometer and Spectrum Analyzer. (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. (Your electrician doesn’t even do this!)
(Please note: 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, must 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 is 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 of the 5G Network and much more, At Elexana, we can measure RF analyzed in 3-D as low from 50 Hz to 60 GHz.
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.
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.
