Last updated: March 2026

By accessing and using RadonByZipCode.com (https://radonbyzipcode.com), you agree to the following terms and conditions. If you do not agree, please discontinue use of the site.

Use of Service

RadonByZipCode.com is a free informational tool that provides radon zone data based on the EPA Map of Radon Zones and CDC Environmental Health Tracking data. The service is intended for general reference and educational purposes only.

Data Accuracy

Radon zone data displayed on this site is sourced from the EPA Map of Radon Zones and CDC Environmental Health Tracking. These represent county-level averages and classifications. Radon levels are highly variable — homes in the same neighborhood can have vastly different radon concentrations.

The only way to know your home’s radon level is to test your home. You can purchase a radon test kit from your state radon program or a certified lab. Do not rely on zone classifications alone to determine your risk.

We make reasonable efforts to keep data accurate and up-to-date, but we do not guarantee the completeness, reliability, or accuracy of any information on this site.

The design, layout, and original content of RadonByZipCode.com are the property of the site operator. Radon data is derived from publicly available EPA and CDC sources. You may reference our data with attribution but may not reproduce the site’s design or substantial portions of content without permission.

Prohibited Uses

Scrape, crawl, or systematically download data from this site using automated tools
Use the site in any way that could damage, disable, or impair the service
Redistribute our data in bulk or create derivative datasets for commercial sale
Misrepresent the source or accuracy of information obtained from this site
