Understanding EMF Exposure by Region

EMF Radar tracks both RF sources (cell towers) and ELF sources (transmission lines, substations) to give you a complete picture.

Urban Areas

NYC, LA, Chicago, etc.
Cell Tower Density Very High
Power Grid Density High
Typical EMF Score 60–90

Dense concentrations of 5G and LTE towers plus extensive power grid infrastructure produce the highest EMF scores.

Rural & Suburban

Smaller cities, rural towns
Cell Tower Density Low
Power Grid Density Varies
Typical EMF Score 10–40

Fewer towers and less infrastructure mean lower RF scores, though proximity to transmission lines can still create ELF hotspots.

Combined exposure

The combined EMF score is weighted toward whichever source contributes more exposure at your location. A city with many cell towers but no power lines will have a high RF sub-score but a low ELF sub-score.

What the Scores Mean

0 25 50 75 100
Low (0–40)

Common in suburban and rural areas. Fewer towers and limited power infrastructure nearby.

Moderate (41–70)

Typical of mid-size cities or suburbs near major infrastructure corridors.

High (71–100)

Dense urban areas with many towers, power lines, and substations concentrated nearby.
