Centennial Nationally

Centennial's RF score of 64 puts it in the bottom quarter nationally — lower cell tower exposure than roughly 75% of US cities we track.

5G in Centennial

Centennial has just 7 5G towers so far — a small fraction of the network. Most wireless coverage relies on 4G LTE and older technologies. As carriers like T-Mobile continue rolling out 5G, this will change, potentially shifting RF exposure patterns in the area.

What Centennial's Tower Density Means for Residents

With 22.2/mi², Centennial has dense tower coverage. Many residents have at least one tower within a few blocks, but EMF scores still range widely — from 11 to 100. Even in a dense tower environment, your exact location relative to tower clusters makes a significant difference.

64

Centennial's RF exposure is rated Elevated

Cell towers are the primary driver of EMF exposure in Centennial, and many residents have elevated RF from nearby infrastructure. Search your address to see how your specific location compares.

What This Means for You

For a city of 108,418 people, Centennial has a high concentration of wireless infrastructure — about 59.1 towers per 10,000 residents. Your personal exposure depends on how close towers are to your home, especially to bedrooms. Search your address to see exactly which towers affect you.

How Power Lines Affect Centennial Residents

Centennial has 20 transmission lines and 9 substations within 5 miles of the city center. The highest-voltage lines in the area carry up to 230 kV. ELF fields drop off sharply with distance — most homes beyond 300-500 meters from a transmission line see very low exposure. But for homes closer than that, especially near higher-voltage corridors, the impact can be significant.

Substations Near Centennial

There are 9 substations in the area, where high-voltage power is stepped down for local distribution. Like transmission lines, their ELF fields drop off quickly with distance. If you can see a substation from your home, it's worth checking your address to see how it affects your score.

19

Centennial's ELF exposure is rated Low

ELF isn't the main concern here — cell towers contribute far more to Centennial's overall EMF picture. Most residents are far enough from power infrastructure that it has minimal impact.

RF vs ELF in Centennial: Cell towers are the clear dominant factor in Centennial's EMF environment (RF: 64 vs ELF: 19). Choosing a home away from tower clusters will have the biggest effect on reducing your overall exposure.

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.

Understanding EMF, RF & ELF

What the scores mean and how they're measured in Centennial

EMF

Electromagnetic fields from cell towers and power lines. Centennial's combined score: 68/100.

RF

Radio frequency from wireless infrastructure. Centennial has 641 cell towers (7 are 5G) → RF score: 64.

ELF

Extremely low frequency from power grid. Centennial has 20 transmission lines and 9 substations → ELF score: 19.

EMF Exposure & Health

Centennial's Elevated EMF score means understanding exposure risks is especially relevant

Sleep Quality

Studies have found measurable effects on sleep quality from RF-EMF exposure, though effect sizes vary.

Children

Some researchers recommend lower limits for children, citing developing nervous systems and longer lifetime exposure.

Precautionary Principle

Many choose to minimize exposure based on the precautionary principle: when science is uncertain but consequences may be significant, reducing exposure is reasonable.

Cell Tower & EMF FAQ for Centennial

How many cell towers are in Centennial?
Centennial has 641 registered cell towers, of which 7 are 5G. That's a density of 22.2/mi² across the city's 28.9 square miles.
Is 5G available in Centennial?
Yes, Centennial has 7 active 5G towers. 5G uses higher-frequency RF signals and typically requires more antennas placed closer together, which can increase localized RF exposure.
What is the average EMF score in Centennial?
Centennial's overall EMF score is 68 out of 100 (Elevated). This breaks down into an RF score of 64 (cell towers & wireless) and an ELF score of 19 (power grid). Scores range from 11 to 100 across the city, so your specific location matters.
How does Centennial compare to other cities in Colorado?
Centennial ranks #10 out of 14 cities in Colorado for EMF exposure (lower rank = less exposure). Some of the lowest-exposure cities in the state include Greeley (40), Longmont (42), Boulder (45), Pueblo (47), Fort Collins (49).
Are there power lines and substations near Centennial?
Centennial has 20 high-voltage transmission lines and 9 substations within the city area. These contribute to ELF (extremely low frequency) exposure, which is measured separately from RF (cell tower) exposure. The ELF score for Centennial is 19 out of 100. Use the map above to see exactly where power grid infrastructure is located.
Which parts of Centennial have the lowest EMF?
EMF scores across Centennial range from 11 to 100, which means location within the city makes a real difference. Areas farther from cell tower clusters and major power line corridors typically score lower. Use the address search above to check specific streets and neighborhoods you're interested in.
