Ecosense Launches US Interactive Radon Map

San Jose, California - February 19, 2026 - Understanding radon exposure starts with knowing where to find reliable information. Ecosense, an innovator in smart radon detection technology, has launched the Ecosense US Interactive Radon Map, a new online platform designed to make radon risk data easier to explore and understand.

Available at radonmap.ecosense.io, the interactive tool brings together publicly available environmental health data to help homeowners, renters, property managers, and building professionals explore regional radon trends. By making this information more accessible, Ecosense aims to help people make informed decisions about indoor radon testing and ongoing monitoring.

What Is the Ecosense Interactive Radon Map?

The Ecosense Radon Map is an online resource that visualizes radon-related data across the United States. Instead of navigating separate datasets and technical reports, visitors can explore geographic patterns through an interactive, color-coded map.

The platform combines publicly available information from participating state health department datasets and the CDC Environmental Public Health Tracking Network. Where appropriate, anonymized Ecosense measurement insights provide additional regional context.

Users can explore the national map, zoom into specific areas, and enter a ZIP code to access available local information. Regional summaries present key statistics that help visitors understand reported radon measurements in their area.

The platform is designed to make environmental health information easier to interpret, whether someone is researching a new home, managing a commercial property, or planning radon testing for an educational or assisted living facility.

How to Use the US Interactive Radon Map

Exploring local radon information is straightforward. Follow these steps to get started.

1. Open the map: Visit radonmap.ecosense.io to access the interactive platform.
2. Explore your location: Use the color-coded US map to review regional radon risk patterns.
3. Enter a ZIP code: Search for your area to access available local data.
4. Review the statistics: Examine the regional summary to understand reported radon levels and the proportion of readings above the EPA action level.
5. Plan your next step: Use the information as a starting point for deciding whether to test your indoor environment or investigate existing test results further.

Local summaries include several useful data points:

• Median radon test results: The middle value among the measurements represented in the dataset.
• Percentage above the EPA action level: The proportion of reported readings at or above 4 picocuries per liter (pCi/L).
• Highest recorded radon levels: The maximum measurement represented in the available data.
• Data source attribution: Information identifying the sources used to compile the regional statistics.

These indicators provide useful context, but their interpretation depends on the available data, the number of measurements, and the locations represented.

Why Radon Risk Data Matters

Radon is a naturally occurring radioactive gas produced by the breakdown of uranium in soil and rock. It can enter buildings through openings in foundations and accumulate indoors. Because it is invisible and odorless, people cannot reliably identify elevated radon levels through their senses alone.

Long-term exposure to radon increases the risk of lung cancer. The US Environmental Protection Agency identifies radon as a significant indoor air quality concern and recommends testing homes regardless of location.

Regional data can help communities understand where additional testing and awareness efforts may be valuable. It can also help homeowners and property professionals ask better questions about indoor air quality.

However, a geographic risk rating does not establish whether an individual property has elevated radon. Indoor levels can vary between neighboring buildings, even within the same ZIP code. A low-risk designation should never replace an actual radon test.

Understanding the EPA Radon Action Level

When reviewing local radon statistics, it is important to understand the EPA's recommended action threshold.

• At or above 4 pCi/L: The EPA recommends fixing a home when radon levels reach this concentration.
• Between 2 and 4 pCi/L: The EPA recommends considering a reduction in radon levels.
• Below 2 pCi/L: Lower readings indicate less exposure, but they do not mean that radon presents zero risk.

These guidelines help people interpret indoor radon test results and determine when further action may be appropriate. They should not be confused with the color categories used to represent regional risk on a map.

What Should You Do After Checking Your ZIP Code?

The map is a starting point for understanding local conditions, not a substitute for measuring radon inside your building.

Whether your area appears to have low, moderate, or high regional risk, consider these practical steps:

• Test your indoor environment. Use an appropriate radon test to measure the concentration inside your home or building.
• Understand your results. Review the measured level, testing duration, and applicable guidance before deciding what to do next.
• Follow up on elevated readings. If results are elevated, consult qualified radon professionals about appropriate confirmation and mitigation options.
• Consider ongoing monitoring. Radon concentrations can fluctuate over time. Continuous monitoring can help reveal changes and longer-term patterns in indoor conditions.

For homeowners who want more immediate visibility into indoor radon levels, Ecosense offers smart radon monitors that provide measurements and help users track changes over time. Explore the available Ecosense radon detectors to learn more about monitoring options.

How Ecosense Is Advancing Radon Awareness

The launch of the Ecosense Radon Map extends the company's work beyond radon detection devices into environmental data accessibility and education.

By bringing multiple public datasets into one interactive experience, the platform helps make regional information easier to explore. Its data-driven approach can support homeowners, property managers, educators, and other professionals who want to understand radon exposure and encourage informed testing decisions.

Ecosense CEO Insoo Park explains that making radon data easier to understand can help people and businesses make better-informed decisions about testing and continuous monitoring. The essential message remains that regional statistics cannot confirm the conditions inside a particular building.

As additional data becomes available, Ecosense intends to continue improving the map and expanding the information it provides.

Frequently Asked Questions

Can I check radon levels by ZIP code?

Yes. The Ecosense Radon Map allows visitors to enter a ZIP code and explore available regional radon information. The results provide context about reported measurements, not a direct measurement of your home.

Does a low-risk area mean my home is safe?

No. Elevated radon has been found in areas classified as low risk. The EPA recommends testing every home because geographic maps cannot determine the actual indoor concentration.

What radon level requires action?

The EPA recommends fixing a home at 4 pCi/L or above and considering action when levels fall between 2 and 4 pCi/L.

Why consider continuous radon monitoring?

Continuous monitoring can help users observe changes in indoor radon concentrations and review trends over time. It complements the process of understanding and managing indoor radon exposure.

Explore the Ecosense Radon Map

Understanding regional radon risk is an important first step toward better indoor air quality awareness. The Ecosense US Interactive Radon Map makes available data easier to explore, helping individuals and organizations make more informed decisions about testing.

Explore your area on the Ecosense Radon Map and use the information as a starting point for understanding local trends. Then take the next step: test your indoor environment and consider appropriate monitoring or mitigation measures based on your results.

Knowing your actual indoor radon level, not just your ZIP code's risk category, is the key to making informed decisions.
