We treat the corrections log as part of the product. Any time we change a factual claim — in the dossier, on a guide page, or in the methodology — we post the change here with a date, the old text, the new text, and the source that triggered the fix. This is how an honest reference works.
Current log
This page is intentionally empty for now. The site launched its public Tier 1 and Tier 2 content on 30 June 2026; corrections will be appended below as they occur. The existence of this page — and the editorial commitment to use it — is the EEAT signal, not the count of entries.
How to report a factual error
Email hello@radonzonereport.com with:
- The exact URL where the error appears (e.g.
/guide/epa-radon-zones-explained/). - The exact text of the claim you believe is wrong.
- The source you believe contradicts it (a federal publication, peer-reviewed paper, or state agency dataset).
We respond within five business days. Confirmed errors are corrected on the page within 24 hours of confirmation and logged here within 7 days.
What we will log
We log any change that affects a factual claim — a number, a citation, a date, a regulatory threshold, a publication ID, a study finding, or a statement of fact about radon, mitigation, EPA policy, or AARST standards.
We do not log:
- Minor copy-editing (typos, formatting, broken HTML).
- Design or layout changes that do not change the substance of any claim.
- The addition of new pages, guides, or sources (those are noted in the changelog, not as corrections).
- Re-wording for clarity where the underlying claim is unchanged.
Entry format (for reference)
When entries are added, each will follow this format:
| Date | Page | Previous claim | Corrected claim | Source |
|---|---|---|---|---|
| YYYY-MM-DD | /path/ | Old text | New text | Publication ID and link |

Every figure dated. Every source named. If we're wrong, the fix lands here.
