Terms of Use

Last updated: September 2026

By using radongrade.com you agree to these terms. If you do not agree, please do not use the site.

Informational content

All content is provided for general information. Predicted radon values are modeled estimates for areas and are not measurements of any property; they are not a substitute for a radon test. See the Disclaimer, which is part of these terms.

Use of the site

You may view and share pages for personal, non-commercial use. You may not scrape the site at a rate that degrades it, republish substantial portions of our pages as your own, or use the site for any unlawful purpose.

Data and licenses

Underlying radon predictions are from the National Radon Exposure Model (CC0 1.0). EPA and Census data are US-government public domain. Minnesota test data is published by the Minnesota Department of Health. Our text, page design and derived aggregations are ours; the underlying public data remains free for anyone to use from its original source.

Affiliate links

Some links are affiliate links; we may earn a commission on purchases. Merchants' own terms govern any purchase. We do not sell products.

The site is provided "as is" without warranties of any kind, express or implied, including accuracy, completeness, fitness for a particular purpose or availability.
