24 Hour Infrastructure Assessment
For homes near power lines, substations, transformers, cell sites or data centers.
FieldWise EMF Consulting measures exactly how much of that infrastructure reaches inside your home, room by room, then logs your bedroom for a full 24 hours so you see what happens while you sleep. Every reading is compared to Building Biology SBM-2015 guidelines and explained in a written report with a clear action plan.
Is this for you?
If you can see one of these from your yard, or you've wondered whether it reaches your kids' rooms, this is the assessment that answers the question.
Why 24 hours
The magnetic field from a power line depends on how much current is flowing through it, and that changes all day long. When your neighborhood comes home in the evening and turns on lights, appliances and air conditioning, the load climbs. So does the field reaching your home.
That means a reading taken at 2 pm can look completely different from one taken at 10 pm, right when you're going to bed. The 24 hour log shows the whole pattern, including the hours you're asleep.
Night matters most. Dr. Robert O. Becker showed that the body runs on its own subtle electrical signals, and his research found that strong outside fields do interfere with them. Dr. Jack Kruse points to sleep as the time the body does its deepest repair. Knowing what your bedroom looks like overnight is the clearest place to start.

What the research shows
Researchers have measured homes near transmission lines, transformers and cell towers for decades. These findings are why the 24 Hour Infrastructure Assessment measures over a full day, room by room.
Adults living near a 735 kV transmission line wore meters for 24 hours. Their homes averaged 7.1 mG (6.8 mG during sleep), compared with 1.6 mG (1.1 mG during sleep) for people living far from any line. The field rose and fell with the electrical load on the line.

In 142 electric utility workers, those with the most steady magnetic field exposure had lower levels of a melatonin metabolite after work. The effect was stronger in workers who also got the least light during the day, which is why light and fields are worth measuring together.

The WHO’s International Agency for Research on Cancer classifies power frequency magnetic fields as Group 2B, possibly carcinogenic to humans. The classification rests mainly on studies linking long term average fields above about 3 to 4 mG with childhood leukemia.

A large UK study found a relative risk of 1.69 for childhood leukemia among children born within 200 m of high voltage lines, and 1.23 at 200 to 600 m. The authors noted the pattern reached farther than magnetic fields alone would explain, so the cause is still unclear.
Draper G, et al. BMJ, 2005. Read the study
In 41 apartments across 10 buildings with indoor transformer stations, apartments directly above the transformer averaged 4 mG, while all other apartments averaged 0.6 to 1.2 mG. What sits under or beside a room matters.

In 354 homes within 250 m of a cell tower, the tower was the main wireless source in 64% of them. Exposure depended on window position, line of sight to the antenna and which floor the home was on, not just distance.

Research on EMF and health is still developing, and some findings are mixed. FieldWise reports what is measured in your space, compared to Building Biology SBM-2015 guidelines. It does not diagnose or treat any condition. That is exactly why a 24 hour measurement beats a guess. See the full research library →
What's included
Radio frequency, AC magnetic and electric fields, body voltage with a 9 point sleeping area sweep, dirty electricity and lighting, measured room by room. See the Foundational
The Gigahertz Solutions NFA1000 records your bedroom around the clock, so the report shows exactly when fields peak and how high they go.
Measured with the TriField EM100 to help separate what's generated inside your home from what arrives on the utility line. That tells you which fixes are in your control.
Measurements taken toward the nearby line, substation or transformer, showing how the field changes with distance.
Room by room results interpreted against Building Biology SBM-2015, with prioritized steps starting with what matters most. Delivered within 4 days of logger pickup.
We walk through every number together until it all makes sense. Most calls run 30 to 60 minutes.
A second call after you've had time to act on the report and come back with questions.
Your 24 hour log as one clear graph with your sleep hours marked, easy to share with family or your utility.
Plain language questions to ask your utility, and what their answers mean.
Every reading is personally reviewed. After your visit, about 3 hours goes into going through your readings room by room, interpreting them against Building Biology SBM-2015 guidelines and building a prioritized plan specific to your home.

How it works
We talk through your home and what's nearby, and confirm this is the right fit.
3 to 4 hours of room by room measurement, property line readings, and the logger set in your bedroom.
I return to collect the logger. Your written report, with the 24 hour data, follows within 4 days.
Your action plan call to walk through everything, then a follow up consult when you're ready.

Our promise
If you complete a fix I recommend and the reading in that area doesn't measurably drop, I'll come back within 90 days and remeasure it at no charge.
Questions
Yes. The assessment measures the magnetic and electric fields in each room and logs your bedroom for 24 hours, so you can see exactly how much reaches the places you sleep and spend time, and when it peaks. It measures exposure. It does not diagnose health effects.
Fields from power lines and transformers rise and fall with how much electricity the neighborhood is using. A daytime reading can look very different from 10 pm, when homes nearby are running lights, appliances and air conditioning. The 24 hour log captures the full daily pattern, including the hours you are asleep.
No. The logger is placed during the visit, usually in the main bedroom, and stays in one spot. I return the next day to collect it. You can go about your normal routine.
Magnetic fields from outside lines pass through walls, so the most effective changes are usually about where you sleep and spend the most time. Your report shows where readings are lowest and lists prioritized options. FieldWise never recommends EMF protection gadgets.
Yes. Radio frequency from nearby cell sites is measured room by room during the visit, and dirty electricity is measured and checked for whether it starts inside the home or arrives on the utility line. The 24 hour log itself records magnetic and electric fields.

Booking details
A travel fee may apply outside the Front Range, based on location and scheduling. For this assessment it covers both the visit and the next day logger pickup.
Life happens, and rescheduling is easy. Each assessment reserves a half day or more on my calendar that no one else can book. With at least 24 hours notice, your deposit moves to your new date. Cancellations or missed appointments with less than 24 hours notice forfeit the deposit.
A 20% deposit ($290) reserves your date. The balance is due when the assessment is complete.
