Public‑health agencies classify radon levels into several ranges based on long‑term exposure research. This tool shows you which category your radon test result falls into.
Your radon test result:
Does anyone who lives in the home smoke?
Check any that apply:
How long have you lived here?
Do you expect to stay in the home?
Major renovations in the last 12 months?
How comfortable are you with risk?
Would cost be a barrier to mitigation?

This tool estimates how much radiation each family member receives from your home’s radon level each year, based on their typical living patterns. It does not measure exact dose, but it shows how radon can affect people differently within the same home.
This level is used to estimate each family member’s annual radiation dose from radon.
Your radiation dose depends on two things: the radon level in the air and the amount of time you spend in your home. The higher the level and the more time spent breathing that air, the more radiation your lungs receive over time.
Radon gives off tiny bursts of energy that can occasionally damage DNA in the cells lining the lungs. The amount of this damage depends on both the radon level and how much time a person spends breathing that air. Very low levels add very small amounts of risk, while higher levels add more over many years.
Most radon guidance is based on generalized metrics. This report is different. It shows how radon affects each person in your home based on where they spend their time. The doses shown here are estimates, not precise medical measurements, and are intended to be considered together with your Navigator Home Report and other tools.
People who spend more time in higher-radon areas of the home receive higher estimated doses.
| Person / role | Estimated annual dose (mSv) | Context |
|---|
Context descriptions compare each person’s estimated dose to typical U.S. background radiation (about 3-4 mSv per year). Background radiation is the natural radiation everyone is exposed to every day from the earth, the air, cosmic rays, and ordinary life.
Different people in the same home can receive different amounts of radiation from the same radon level. This report helps you see who has the highest meaningful exposure while still making a decision that fits your whole family. Some families choose to mitigate now, others choose to monitor and plan. These individualized dose estimates are one piece of information to consider alongside your radon level, your home’s characteristics, and your family’s circumstances.
There is no single "right" choice—the best decision is the one that fits your family.
Mitigation reduces radon by creating controlled airflow beneath your home and safely venting it outside. This is the foundation for understanding the tradeoffs in the cards that follow.
Mitigation is a one‑time investment with long‑term benefits. Costs vary by home type, system design, and installer practices.
When installed correctly, mitigation reliably reduces radon — often by 80–99%. The system runs continuously to keep levels low.
Fans are quiet, but placement matters. Systems are visible outside the home, though good routing keeps them discreet.
Systems require very little from homeowners. Fans last many years, and most components never need replacement.
