A comprehensive roadmap to an optimized electrical environment.
This environment has been evaluated according to the rigorous Building Biology Institute (BBI) guidelines. We test for and mitigate four primary exposures: Electric Fields (EF), Magnetic Fields (MF), Radio Frequency (RF), and Dirty Electricity (DE). We optionally evaluate Body Voltage, nearby cell phone towers, biological lighting quality, and appliance noise and load based on customer preference for allotted measurement time.

Hi {Client Names},
Thank you for trusting me to assess your home's electrical environment. Your property has an excellent foundation—specifically a remarkably clean grid baseline when internal loads are off. While we did find several severe localized point sources driven by standard modern technology (WiFi, network switch, smart controllers, LED lighting, and EV chargers), the great news is that these are highly fixable. We can eliminate many of the highest exposure peaks with simple, zero-cost adjustments. Taking the steps outlined in this report will create prompt, meaningful improvements to your daily biology and sleep quality.
The following ratings are based on the latest SBM-2024 Precautionary Guidelines and EMRS clinical daytime standards. These standards are significantly more stringent than FCC or utility guidelines, focusing on long-term biological health and minimizing cumulative daily load rather than short-term tissue heating.
No Concern
The ideal state. Matches nature closely and provides the optimal environment for biological resting and regeneration.
Slight Anomaly
A minor deviation from nature. Acceptable for daytime living/working areas.
Severe Anomaly
Not recommended for long-term exposure. Poses a biological burden. Remediation required.
Extreme Anomaly
Significantly elevated levels that require mitigation and protective strategies to restore biological safety.
*Note: The SBM-2024 standard uses intense terminology. An "Extreme Anomaly" simply indicates a significant deviation from natural background levels requiring mitigation, not an imminent danger. Don't panic—these are entirely resolvable.
**Note: The official SBM-2024 standard utilizes Nanotesla (nT) for magnetic fields. For ease of use with US standards, we have converted these to Milligauss (mG), where 1 mG = 100 nT.
How to Read This Report: The gauges below illustrate your CURRENT AMBIENT and CURRENT PEAK exposure levels, the improvements from free/easy QUICK start steps, and the final optimized levels after ADVANCED mitigation.
A Phased Approach: Do not feel pressured to tackle everything at once! EMF mitigation is best done in stages. Start with the Quick-Start checklist for prompt relief, and gradually implement the Advanced strategies over the coming months. Every single step is a win for your biology.
The Physics of Distance: While some peak readings below sound alarming, RF power and magnetic fields drop exponentially with distance via the inverse-square law. Moving just 6 to 10 feet away reduces this physical exposure by over 99%. Distance is your best friend!

By identifying and isolating point-sources during the visit, we were able to drop peak exposures drastically in key areas.
Bed 1 Ambient RF
Access Point Disabled
Before (Extreme)
726,000 µW/m²
After (No Concern)
97 µW/m²
We accomplished this by turning off the access point wifi in the Unifi network settings. Ethernet still works.
Bath Heat Controllers
Breaker Disabled
Before (Extreme)
249,000 µW/m²
After (No Concern)
28 µW/m²
We eliminated this microwave pulse source by identifying the dedicated circuit and shutting off the bathroom heat controller breaker.
Bed 3 Router
WiFi Low Power Mode
Before (Extreme)
1.05M µW/m²
After (Slight)
13,000 µW/m²
We accessed the router's administrative settings and reduced the transmit power from 100% down to a low-emission state.
Our comprehensive assessment of the primary residence and shop revealed several significant areas of concern regarding electromagnetic fields (EMF), along with some excellent baseline conditions. Understanding these key vectors will clarify why we are taking the steps outlined in the Quick-Start and Advanced strategies.
Multiple localized WiFi access points were acting as massive RF point sources. All three bedrooms had a WiFi access point located directly behind the headboard, emitting heavily into the sleeping environment. Smart floor heater controllers were also emitting continuous high-level RF pulses.
The most severe localized DE spikes are driven by LED flood lights on both the main house and shop (spiking up to 1950mV), the Ethernet switch on the dining circuit (spiking to 1440mV), {Client Name}'s personal computer (470mV), and both EV chargers (spiking over 1100mV when booted).
Beds 1 and 2 showed significant body voltage (up to 6.0 V) driven primarily by ungrounded, plugged-in bedside lamps and alarm clocks. This places a continuous biological stress on the body during hours designated for resting and regeneration.
When all breakers are turned off, the baseline DE from the grid is excellent (~20mV). This is a fantastic starting point. However, the "idle" baseline with circuits on operates at a highly elevated >1200mV due to internal loads (network switch, etc).
We've already taken several critical actions during the assessment. Follow these remaining zero-to-low-cost steps for an immediate, effective reduction in daily exposure.
This section provides a simplified overview of the most notable exposure points in the home. The tables below highlight the highest localized source found in each room alongside the general ambient level.

Think of Electric Fields (V/m) as the 'pressure' in the room, and Body Voltage (mV) as how much of that pressure is actually being absorbed by the human body. Body voltage is the ultimate proof of whether our AC Electric Field mitigation actually works. It measures the exact AC voltage induced directly onto the skin from the surrounding environment. During the assessment, we perform mock-ups of mitigation steps to gather estimated data before permanent mitigation is completed.
| Location | Baseline (mV) | Quick Mitigation (mV) | Net Change |
|---|---|---|---|
| Bed 1 | 3300 | 140 | -3160 mV (-96%) |
| Bed 2 | 6000 | 240 | -5760 mV (-96%) |
| Bed 3 | 700 | -- | -- |

| Massage Chair | 9500 | 1700 | -7800 mV (-82%) |
| Office Nook | 1700 | 1000 | -700 mV (-41%) |
Light is a profound biological trigger that regulates circadian rhythms, energy levels, and the nervous system. Not all artificial lighting is created equal. The bulbs and fixtures used in the home vary significantly in quality—ranging from healthy, biologically supportive options to those that cause unseen physiological stress through their color spectrum, invisible flicker, and electrical emissions.
External Radio Frequency (RF) sources, such as macro cell towers and microwave relay antennas, establish the baseline environmental exposure for the property.
Phase 2 Long-Term Upgrades
Because the baseline grid power is clean (~20mV) but the internal loads (network switch, solar inverter, EV chargers, subpanels) drive the ambient DE over 1200mV, a heavy-duty capacitive filter installed directly at the main panel is highly recommended.
The LED floodlights on both the main house and the shop are introducing severe transients onto your electrical wiring. These fixtures need to be replaced with low-EMI LED equivalents or traditional incandescent/halogen fixtures.
Since we've already turned off two of the three WiFi access points, the overall network emissions are vastly improved. For the final active access point in Bedroom 3, we recommend replacing it with a specialized Low-EMF WiFi router (such as a JRS Eco) that pulses significantly less. Additionally, moving the bed in Bedroom 3 to maximize physical distance from the access point / router will drop exposure further.
To prevent having to manually use outlet switches to turn off lamps and alarm clocks every night to achieve healthy Body Voltage, consider having an electrician install a remote cut-off switch (Demand Switch) for the sleeping quarters.
You do not have to navigate this alone. Now that you have the data and a clear roadmap, the next step is to review this together, answer any questions, and begin coordinating your Quick-Start items.
Included in your assessment is a follow-up call to review these findings and help you prioritize your remediation budget.

The tables below contain the full 9-point perimeter mapping data and localized condition tests for the property, provided for technical review and reference by mitigation contractors.
(Most Stringent Guidelines)
Measurements are collected by mapping each room to a standardized 9-point grid. The wall facing the property's main front door is designated as the "A-Wall." We record measurements at the four corners (AD, AB, BC, CD), the centers of the four walls (A, B, C, D), and the Center of the room to identify where fields are pooling or entering the space. All perimeter measurements are taken 18" from the wall.

Phased Ambient & Peak Exposure Estimates
This table explicitly documents the physical actions driving the visual gauges in Section 1. It details the precise Ambient and Peak measurements across all three implementation phases: Current (baseline), Quick (immediate remediation), and Advanced (long-term infrastructural upgrades).
| Type | Phase | Ambient | Peak | Rationale / Action Taken |
|---|---|---|---|---|
| Electric Fields (EF) SBM: <1 V/m | Current | 10 V/m | 60 V/m | Elevated ambient in Bed 3. High localized peaks from Bed 2 Lamp and Bed 3 Massage Chair. |
| Quick | 0 V/m | 1 V/m | Use manual outlet switches for Bed 1 & 2 lamps and Bed 3 massage chair. | |
| Advanced | 0 V/m | 1 V/m | Remote demand cut-off switches installed or bedroom breakers off at night. | |
| Magnetic Fields (MF) SBM: <0.2 mG | Current | 0.2 mG | 20.0 mG | Excellent grid baseline. Localized 20mG peak from old alarm clock by headboard. |
| Quick | 0.1 mG | 1.2 mG | Relocated alarm clock >6 feet from bed. | |
| Advanced | 0.1 mG | 0.1 mG | Demand switches eliminate all active current/magnetic field generation during sleep. | |
| Radio Frequency (RF) SBM: <10 µW/m² | Current | 5.4K µW/m² | 87K µW/m² | Multiple active APs. Bed 3 Printer idling. Floor heaters actively pulsing. |
| Quick | 13K µW/m² | 13K µW/m² | Disabled Bed 1 & 2 WiFi. Turned off Bath 1 & 2 Heaters. Set Bed 3 WiFi to Low Power (13K peak remains). | |
| Advanced | <10 µW/m² | <10 µW/m² | Full network hardwiring and/or installation of JRS Eco specialized low-EMF router in Bed 3. | |
| Dirty Electricity (DE) SBM: <25 mV | Current | >900 mV | >500 mV | House-wide noise from network switch, inverter, EV chargers, and floodlights corrupting sleeping circuits. |
| Quick | >900 mV | >500 mV | No effective quick step for grid-wide infrastructure line noise. Network switch local filtering will help. | |
| Advanced | ~20 mV | ~20 mV | Main panel heavy-duty capacitive filter installed, scrubbing noise before it enters branch circuits. |
| Vector | Phase | Ambient | Peak | Rationale / Action Taken |
|---|---|---|---|---|
| Electric Fields (EF) SBM: <1.5 V/m | Current | 1 V/m | 350 V/m | Ambient is naturally clean. High peaks when near active electric stove or plugged-in tea kettle. |
| Quick | 1 V/m | 350 V/m | Use manual outlet switch for tea kettle (removes 115 V/m). Stove peak remains as it is necessary for cooking. | |

| Dirty Electricity (DE) SBM: <25 mV | Current | >900 mV | 1950 mV | Massive switch-mode spikes from Dining Ethernet Switch (1440mV) and Flood Lights (1950mV). |
| Quick | >900 mV | 1950 mV | No effective quick step. | |
| Advanced | ~20 mV | ~20 mV | Whole house filter scrubs main panel. Replace LED floodlights with low-noise alternatives. |
| Vector | Phase | Ambient | Peak | Rationale / Action Taken |
|---|---|---|---|---|
| Electric Fields (EF) SBM: <1.5 V/m | Current | 0 V/m | 33 V/m | Excellent baseline, completely zeroed out in center. Mild peak near B Wall. |
| Quick | 0 V/m | 33 V/m | No action necessary. | |
| Advanced | 0 V/m | 33 V/m | No action necessary. | |
| Magnetic Fields (MF) SBM: <0.2 mG | Current | 0.1 mG | 6.0 mG | Shop naturally clean. 6.0 mG peak solely generated when EV Charger is actively drawing load. |
| Quick | 0.1 mG | 6.0 mG | Magnetic fields cannot be easily shielded; they must be managed via distance. | |
| Advanced | 0.1 mG | 6.0 mG | No infrastructural change planned. Maintain 3-5 feet of distance when EV is actively charging. | |
| Radio Frequency (RF) SBM: <100 µW/m² | Current | 1.5K µW/m² | 15K µW/m² | WiFi AP in Utility Closet broadcasting loudly (15K). |
| Quick | 1.5K µW/m² | 15K µW/m² | If WiFi is needed in Shop, no quick action taken. Values remain. | |
| Advanced | 1.5K µW/m² | 15K µW/m² | No infrastructural change planned for the Shop AP. Maintain distance or toggle off when not in use. | |
| Dirty Electricity (DE) SBM: <25 mV | Current | >900 mV | 1150 mV | Shared main subpanel noise (ambient). Massive spike when EV Charger is booted. |
| Quick | >900 mV | 1150 mV | No effective quick step. | |
| Advanced | ~20 mV | 1150 mV | Main panel filter scrubs ambient noise. The 1150mV EV peak will remain when actively charging, but will be isolated. |
