Guides and sources

Guides are written or heavily edited by a named author, who fact-checks every claim against its source before the guide is published. Every health, safety, legal or numeric claim links to where it comes from.

We cite only primary, authoritative sources:

We don't cite blogs, manufacturers, retailers or other commercial sites for facts. Our build checks every guide's links against this list.

Guides are general information, not medical, legal or professional advice. We don't test or fix homes. For advice about your home, contact your state radon program or a certified radon professional.

Reviews

Reviews will be hands-on only. Products are bought or received, run in a real home, and photographed in that home. Readings are logged against a reference device or a lab test. No review is written from manufacturer specifications. We haven't published any reviews yet; seehow we test.

Corrections

If you spot an error, contact us. We fix it, and a corrected guide gets a new "last reviewed" date.
