Yes. Iowa HHS certifies radon testers (measurement specialists, numbers starting RNTST) and credentials installers (mitigation specialists, numbers starting RNMIT). Mitigation rules in effect since July 1, 2026 require national ANSI/AARST installation standards and a level below 4 pCi/L after the system is installed.
