Questions about radon credentials in Kansas

Does Kansas license radon testers and mitigators?

KS KDHE certifies radon work in Kansas and publishes a current list with credential numbers. This site imports that list and re-checks it monthly. 237 current Kansas listings appear here as of August 29, 2026.

How do I verify a radon credential in Kansas?

Open the KS KDHE lookup at https://www.kdhe.ks.gov/1066/Radon-Professionals, search the name, and match the credential number digit for digit. Status can change between our monthly check on August 29, 2026 and the day you hire. If the official page disagrees with this directory, the official page is right.

Is an NRPP or NRSB certification enough in Kansas?

Kansas issues its own radon credential through KS KDHE, so a national NRPP or NRSB certification is not a substitute for it. Every Kansas listing on this site shows the KS KDHE number, not a national one.
