Terms of use
Last updated November 4, 2026
By using this site you agree to these terms. If you do not agree, do not use the site.
Information, not professional advice
Radon content is general information. Mitigation, electrical and building work must follow local code and the manufacturer's instructions. Verify a contractor's certification and any system recommendation with a qualified radon professional before you buy or install anything.
Estimates
Cost figures are estimates based on stated inputs. They are not quotes and do not guarantee a price, an installation outcome, or a radon-test result.
Radon and health
Radon is a radioactive gas, and the risk comes from long-term exposure, not from a single reading. Nothing on this site is medical advice. If a test reads at or above 4 pCi/L, EPA's guidance is to reduce the level; if you have health concerns, speak to a doctor. Do not rely on sealing cracks or opening windows as a substitute for a working mitigation system.

Limitation of liability
The site is provided "as is". To the extent permitted by law, RadonLab is not liable for losses arising from reliance on the content.
