Does a radon contractor need a license in Nebraska?
Yes. Anyone working on a radon project or in a radon occupation in Nebraska must be licensed by DHHS, both individuals (measurement or mitigation specialists) and businesses. DHHS has a free online license lookup.
No test is required. The seller disclosure statement asks about radon gas (yes, no or don't know), asks for copies of any test results, and asks whether the home has been mitigated and when.
Yes, under state law since Sept. 1, 2019: regularly occupied new construction must be radon-resistant, with sealed sump lids, a labeled passive vent pipe from under the slab out through the roof, and a wired circuit where a fan could go. Exceptions include designs by a licensed architect or engineer and counties the state finds average below 2.7 pCi/L.
