For Wisconsin Healthcare Providers: Helping Your Patients Reduce Radon Exposure
Wisconsin has elevated indoor radon — roughly 1 in 10 Wisconsin homes test above the EPA action level, and statewide levels run 4-5x the national average of 1.3 pCi/L (a defensible state-average figure is about 5.7 pCi/L, with state testing aggregates running higher). Radon is the leading environmental cause of lung cancer and the #2 overall cause after smoking. This page summarizes the American Lung Association Healthcare Provider framework, screening guidance, ICD-coding context, and the Wisconsin Radon Experts referral workflow for Wisconsin physicians, NPs, and PA-Cs.

How the calculator maps test results to EPA guidance
| Radon level (pCi/L) | Risk tier | EPA-aligned recommendation |
|---|---|---|
| 0.0 – 1.9 | Below average — low | No action needed. Re-test every 2 years or after major renovation. |
| 2.0 – 3.9 | Elevated — EPA "consider mitigating" | Consider mitigation, especially with smokers, children, or lower-level bedrooms. Run a long-term (90+ day) test for confirmation. |
| 4.0 or higher | EPA Action Level — fix the home | Install an active radon mitigation system. EPA recommends fixing the home as soon as practical. |
The American Lung Association Radon Risk Framework — Summary
The ALA Healthcare Provider Decision Support Tool (2024) is the most-cited US clinical framework for residential radon exposure screening. Below is the ALA + EPA modeled lifetime lung cancer risk table — useful for shared decision-making with Wisconsin patients on whether their home test result warrants mitigation.
| Indoor radon (pCi/L) | Never-smoker lifetime risk | Smoker lifetime risk | EPA / ALA recommendation |
|---|---|---|---|
| 1.3 (US avg) | ~2 in 1,000 | ~20 in 1,000 | No action required |
| 2.0 | ~4 in 1,000 | ~32 in 1,000 | Consider mitigation (esp. smokers / children) |
| 4.0 (EPA action level) | ~7 in 1,000 | ~62 in 1,000 | Mitigate — install active radon system |
| 5.7 (Wisconsin avg) | ~10 in 1,000 | ~85 in 1,000 | Mitigate — above EPA action level |
| 10.0 | ~18 in 1,000 | ~150 in 1,000 | Urgent mitigation; consider interim ventilation |
| 20.0+ | ~36+ in 1,000 | ~260+ in 1,000 | Emergency mitigation; limit time in affected levels |
How to Discuss Residential Radon Exposure with Wisconsin Patients
ALA-aligned conversation script for integrating radon exposure screening into primary care, pulmonology, and oncology visits.
1. Screen — single intake question
"Has your home been tested for radon in the last 2 years?" Add to standard intake forms or annual physical paperwork. Wisconsin's elevated radon levels — roughly 1 in 10 homes above the action level and 4-5x the national average — make this screen materially more clinically relevant than the national-average baseline would suggest.
2. If untested — recommend testing
"Wisconsin homes average several times the national indoor radon level, and about 1 in 10 test above the EPA action level. A short-term test kit costs $15-30, takes 48-96 hours, and tells you if your home is at or above the EPA action level of 4 pCi/L. I'd encourage you to test — particularly because you have [smoking history / children / chronic respiratory condition]." Kits available at hardware stores, ALA, or the Wisconsin Radon Program.
3. If tested above 4 pCi/L — recommend mitigation
"Your test result is above the EPA action level. The ALA framework places your annual lung cancer risk attributable to radon at about [X in 1,000] over a lifetime at this exposure level. EPA recommends installing an active radon mitigation system to bring the home below 2 pCi/L. Cost is $1,000-$2,500 in Wisconsin, not covered by insurance. I can refer you to Wisconsin Radon Experts, who route to NRPP/NRSB-certified mitigation specialists."
4. If tested 2.0-3.9 pCi/L — discuss "consider mitigation"
"Your reading is in the EPA 'consider mitigating' zone. For most non-smoker adults this is a re-test-in-2-years situation. But given your [smoking history / children / respiratory condition / basement bedroom], the ALA framework supports mitigation even in this range." Shared decision-making call.
5. For never-smoker lung cancer presentations — document radon
For Wisconsin never-smoker lung cancer presentations, residential radon is among the leading attributable risk factors. Document residential radon exposure history in social history (test results, mitigation status, duration of residence in home). No ICD-10 modifier exists, but social-history documentation supports clinical reasoning + future epidemiological research.
How Wisconsin Radon Experts Supports Your Patient Referrals
We route Wisconsin HCP-referred patients to NRPP/NRSB-certified mitigation specialists in their area. Free, clean clinical referral pattern — no fees to or from HCPs.
- Refer by phone: Call ((414) 386-2224) with patient consent — we collect patient address, document the HCP referral source, and route within 4 business hours.
- Refer by handoff: Have the patient call us directly + mention they were referred by their physician. We collect the same intake info.
- Refer by form: /contact form — note "HCP-referred" in the message field.
- Documentation provided to patient + HCP on request: NRPP/NRSB certification of installer, written quote, install warranty (5-year fan, lifetime piping), and post-mitigation verification test result documentation suitable for medical records.
- Cost transparency: Typical Wisconsin residential mitigation $1,000-$2,500. We do not charge HCPs or patients any referral fee. The patient pays the installing contractor directly upon completion.
- HIPAA-compatible: No PHI required from HCP — patient initiates contact or HCP shares only patient name + phone with consent.
