EMF Testing & Remediation in Seattle, WA

Electromagnetic fields (EMF) or electromagnetic radiation (EMR) are terms describing various frequencies of energy that exist throughout the universe.  All life has evolved under their influence.  In the last 130 years, mankind has harnessed some of these frequencies for the electrical power grid, wireless communication, artificial lighting, and others.  In doing so, we have made them more focused and powerful, but our biology has not yet adapted to coexist with them in a healthy way.

As a certified Building Biologist and Electromagnetic Radiation Specialist (EMRS) with over 10 years of experience, I provide one of the most thorough EMF assessments available. Unlike many consultants who only cover the basic three (AC Electric Fields, AC Magnetic Fields, and Radio Frequency), I conduct full-spectrum testing that also includes: High Frequency Voltage Transients (Dirty Electricity) measured professionally with an oscilloscope Artificial Light analysis: flicker, color temperature, and associated dirty electricity Comprehensive Electrical System Audit. These advanced evaluations are rarely performed, or are only given cursory attention with inadequate tools by less experienced practitioners. This depth ensures I identify hidden sources of electromagnetic pollution that others routinely miss, delivering truly effective mitigation strategies for sensitive clients. Alternating Current (AC) Electric Fields – AC Electric Fields are produced by the presence of electricity. Their strength is determined by voltage; the higher the voltage or number of sources, the stronger the field. AC Electric Fields are generated by live electrical wires and generally radiate outward 6-8 feet from the source, but in some cases further. An electric field will exist even when a plugged-in electric device is not in use (turned off). In other words, anything plugged in produces a continual emission. AC Electric Fields have a natural attraction to ground and are considered low frequency electromagnetic radiation (5 Hz – 400,000 Hz). AC Magnetic Fields – AC Magnetic Fields are produced by electrical current flow. Any device or appliance that consumes electricity will produce an AC Magnetic Field. A more powerful device will produce a higher magnetic field. These fields usually radiate out 2-3 feet from their source, but can radiate out several hundred feet in the case of high voltage power lines. AC Magnetic Fields are considered low-frequency electromagnetic radiation (5 Hz – 400,000 Hz). Radio Frequency (RF) – RF waves are used to convey information from one place to another through the air. They are used in mobile communication, radio and television broadcasts, radar, satellite navigation and homeland security. They are a core component of our wireless communication infrastructure. Common examples include: Cellular (4G, LTE, 5G mid-band and millimeter wave AM/FM radio weather and airport radar WiFi, BlueTooth, Zigby Digital/Analog TV Emergency Radio "Smart" utility meters These high-energy airborne waves are capable of traveling miles. RF waves are considered high frequency electromagnetic radiation (27 MHz -8 GHz + 20-40GHz 5G mmWave). Artificial Light – Modern artificial light sources connected to the AC power grid such as LEDs, fluorescent bulbs, compact fluorescents, and tech screens introduce multiple forms of biological stress. The vast majority emit significant levels of flicker (visually imperceptible), blue-rich spectra misaligned with natural circadian rhythms, and contribute to dirty electricity on building wiring. These factors are strongly linked in research to circadian disruption, melatonin suppression, sleep disturbances, migraines, eye strain, and increased seizure risk in sensitive individuals. High Frequency Voltage Transients (Dirty Electricity) – High Frequency Voltage Transients, commonly known as Dirty Electricity, consist of erratic high-frequency surges and noise that ride along standard 60 Hz AC electrical wiring. They are produced by core electricity generation, modern electronics, variable speed drives, dimmer switches, LED/CFL lighting, solar inverters, and other devices that interrupt or modulate current flow. These transients typically range from approximately 2 kHz to 100+ kHz (and sometimes higher) and propagate throughout a building’s electrical system, radiating low-level electric and magnetic fields into living spaces. Dirty electricity is considered a form of electromagnetic pollution that adds to the overall EMF burden in the home. Electrical System – National Electric Code violations, current on the grounding conductors, primary and secondary neutral deficiencies, wiring errors, cable current, grounding electrode resistance can all make the EMF profile of your home worse.

We use German engineered, professional grade equipment from Gigahertz Solutions. Additional high-end equipment from Fluke, UPR-Tek, PicoScope, and RFExplorer is used daily.

Building Biology is a discipline developed in Germany that works to maintain our connection to the natural world.  Although modern homes and technology do many wonderful things for us, they can create a disconnect from the health offered by the natural world. By paying attention to the building materials, air & water quality, light, and electromagnetic profile of a home, a health-promoting space can be created for you and your family

Yes, EMF levels are generally higher in dense urban areas like Portland, Seattle, and surrounding metro regions compared to suburban or rural locations. The primary driver is population density. Supporting more people and businesses requires significantly more infrastructure, including: Denser networks of power lines and electric utility substations (which produce stronger magnetic fields due to higher current loads) More 4G/5G cell towers and small cells handling heavy data traffic LED street lighting, public WiFi, and other smart city systems Closer proximity to neighboring homes, apartments, offices, and commercial buildings packed with WiFi routers, Bluetooth devices, smart TVs, digital assistants, computers, and other wireless technology All of these sources contribute to elevated RF radiation, magnetic fields, electric fields, and dirty electricity indoors and outdoors. Real-world data supports this: I consistently measure higher EMF exposures in cities like Seattle and Portland. Don’t let this overwhelm you. As a certified Building Biologist & EMRS with over 10 years of experience helping clients in Pacific Northwest urban environments, I’ve developed proven, practical low-EMF remediation strategies that make a meaningful difference. A professional EMF home inspection is the smartest first step. You’ll receive clear, actionable data on exactly what types of EMF you’re exposed to, their sources and strength levels, and prioritized solutions tailored to your space- whether you live in a high-rise apartment, townhome, or single-family home in Portland, Seattle, Hillsboro, Tacoma, Olympia or elsewhere in the region.

In the last 130 years, mankind has harnessed many of the electromagnetic frequencies in the universe for the electrical power grid, and wireless communication.  We have made them more focused and powerful, but our biology has not adapted to coexist with them in a healthy way. A significant body of research has been done on the biological impacts of non-ionizing EMF, dating back to the 1930s. Numerous recent scientific publications have shown that EMF affects living organisms at levels well below most international and national guidelines. Effects include increased cancer risk, cellular stress, increase in harmful free radicals, genetic damages, structural and functional changes of the reproductive system, learning and memory deficits, neurological disorders, and negative impacts on general well-being in humans. Damage goes well beyond the human race, as there is growing evidence of harmful effects to both plant and animal life. No studies have ever consclusively proved EMF exposures like those typically found in our homes and places of work to be safe. Read some of the research yourself: https://ehtrust.org/science/

Remediation is a separate cost from the inspection, and that is often the first thing people worry about. The honest truth: the scope and cost can vary widely, and it is impossible to say what your home will need before it has been evaluated.Over more than 10 years of hands-on remediations, we have seen the full range. Some homes respond beautifully to a DIY approach of a few hundred to a few thousand dollars: wiring a room for ethernet, changing a few lighting or sleep-area habits, adding targeted filters, or making other simple, high-leverage changes. Other homes need electricians, painters, or IT professionals, and those projects can run into the tens of thousands. We have walked both kinds of jobs, and we do not assume the expensive path is the right one.What the inspection is for is to take the guesswork out. Comprehensive testing shows the significant exposures actually affecting your home. We then turn that data into a prioritized plan in plain language, so you can start with the changes that matter most and skip the ones that do not.Just as important: after a decade of this work, we know there are often equally effective remediations at different price points. We will lay those options out so you can choose what fits your budget now, and what can wait, without feeling like you have to do everything at once.
