0 / 6 done

1. Check local radon guidance and obtain a recognized testing kit or qualified measuring professional.
2. Identify whether the test is short-term or long-term and follow the device's stated duration.
3. Choose a regularly occupied lower-level room per the kit instructions; avoid unsuitable places such as kitchens or bathrooms.
4. Follow closed-house and ventilation conditions exactly as specified for the test; requirements depend on device and duration.
5. Complete the full test period, use the approved analysis process and record the result with its units.
6. If results are elevated under local guidance, arrange follow-up testing or a qualified mitigation assessment rather than improvised fixes.
