How to understand your radon dose
Radon level describes what’s in the air. Dose describes how much of that air you personally breathe based on where you spend time in the home. Two people living in the same house can receive very different doses depending on their daily routines and sleeping location.

This estimate reflects your radon level and your time spent on the level where that measurement was taken.
What this means for you
Your radon level and your personal dose are related but not identical. Radon level shows the potential for exposure. Dose shows your actual exposure based on your home pattern. A higher radon level does not always mean a high dose, and a moderate dose does not mean the radon level is safe.

If your radon level is 4.0 pCi/L or higher, mitigation is still recommended—even when your personal dose falls in the low or moderate range—because reducing radon lowers long‑term risk for everyone in the home.
