About EMF & Cell Towers in Portland
Oregon's electromagnetic field (EMF) exposure landscape reveals significant urban radiation concentrations, with a statewide ranking that places this metropolitan area at the highest risk level among major cities. Portland's EMF score of 65 out of 100 reflects an elevated exposure profile, driven by 783 total cell towers—including 184 5G installations—and a tower density of 5.9 per square mile that contributes to a wide-ranging EMF score spectrum from 10 to 100 across the city. This analysis provides critical insights into the electromagnetic radiation environment that could impact residents' long-term health and technological infrastructure.

Cell Tower Map & RF Exposure in Portland, OR
Carriers Operating in Portland
Portland Nationally
With an RF score of 65, Portland ranks among the lowest 10% nationally for cell tower exposure — significantly less wireless infrastructure than most US cities.
5G in Portland
Portland has 184 active 5G towers, accounting for 23.5% of the local network. T-Mobile leads 5G deployment in the area. The network is still primarily 4G LTE, but as 5G expands, more neighborhoods will have higher-frequency antennas nearby. Searching your address shows which towers — including 5G — are closest to your home.
What Portland's Tower Density Means for Residents
With 5.9/mi², Portland has moderate tower coverage. Some neighborhoods have multiple towers nearby while others have very few — and it shows in the data. Scores in Portland range from 35 to 100, so your specific address matters a lot.
Portland's RF exposure is rated Elevated
Many residents have elevated RF exposure from nearby towers. If you're concerned, search your address to see how your specific location compares and which towers are closest.
What This Means for You
RF exposure from cell towers drops sharply with distance. In Portland, scores range from 35 to 100, which means your specific location matters more than the city average. Search your address to see what's nearby — especially which direction towers are from your bedrooms.
Power Lines & ELF Exposure in Portland, OR
How Power Lines Affect Portland Residents
Portland has 117 transmission lines and 74 substations within 5 miles of the city center. ELF exposure drops off sharply with distance. Homes more than 500 meters from a transmission line or substation typically have very low ELF levels, while homes within a few hundred feet may experience noticeably higher exposure.
Substations Near Portland
With 74 substations in the area, Portland has significant power distribution infrastructure. These are the points where high-voltage power is stepped down for local use. Each one creates a localized ELF field — if you live within a few hundred meters of one, it likely contributes to your score. The map shows exactly where they are.
Portland's ELF exposure is rated Moderate
Some parts of the city are close to power grid infrastructure. If you live near visible power lines or a substation, checking your address will show how much they contribute to your personal EMF score.
RF vs ELF in Portland: Cell towers have a somewhat bigger impact than power lines in Portland (RF: 65, ELF: 49), though both contribute meaningfully. Checking your address shows which sources are most relevant to your specific location.
What This Means for You
Unlike cell tower RF, which is spread across many towers, ELF exposure is very location-specific. You could live a few blocks from a power line and barely notice it in your score, or live right next to one and see a significant impact. Check your address to see if any are close enough to affect your home.
How Portland Compares: Cell Towers & EMF Scores
Portland has significantly higher electromagnetic field (EMF) exposure compared to other Oregon cities, ranking at the top of the state with a score of 65 versus the state average of 41. While the city's elevated EMF levels exceed both state and national medians, nearby lower-exposure alternatives like Salem or Eugene might be preferable for individuals concerned about electromagnetic radiation.
