A live number, not a screenshot

Every county on this site has a small live badge version of its own EPA zone rating — meant for a real-estate listing page, a home-inspection report site, or a local-news piece that references a specific county's rating instead of a screenshot that goes stale if EPA revises the map.

How to add one

Pick any county from this site and use its slug — the part of the URL after the domain, e.g. los-angeles-county-ca for Los Angeles County, CA — in this snippet:

<iframe src="https://radonzonecheck.com/embed?county=COUNTY-SLUG" width="320" height="200"
  style="border:0" loading="lazy" title="Radon zone widget"></iframe>

The credit link inside the widget points back to the county's full page and is marked rel="nofollow", in line with Google's policy on links inside syndicated or embeddable widgets.
