1. Summary
Your home’s radon level: _ pCi/L
Estimated annual radiation dose: _ mrem
Estimated 10‑year cumulative dose: _ mrem
Your radon level determines how much long‑term exposure your lungs receive. The dose numbers below help you understand the scale of that exposure so you can make a confident, informed decision.
2. Annual Dose Estimate
Estimated annual dose: _ mrem per year
This represents the estimated amount of radiation your lungs receive from radon and its decay products over a typical year of living in the home.
3. Cumulative Dose Over Time
- 5 years: _ mrem
- 10 years: _ mrem
- 20 years: _ mrem
Radon risk comes from long‑term exposure. The longer the exposure, the more opportunities for small cellular effects to accumulate.
4. Comparison to Familiar Exposures
- Natural background radiation in some higher‑elevation U.S. cities
- A few routine medical imaging procedures spread across a year
- Everyday environmental radiation from soil, building materials, and cosmic rays
These comparisons are not meant to minimize radon — they simply help you understand the magnitude of the exposure.
5. What Actually Accumulates
Radon gas does not build up in your body. Radiation does not accumulate.
What accumulates is:
- Small DNA effects caused by alpha particles
- Occasional misrepairs that leave behind tiny errors
- Long‑term cellular changes that can add up over decades
Reducing radon reduces how many of these “damage events” occur each year.
6. Decision Guidance
Radiation dose helps you understand the scale of exposure, but your mitigation decision is based primarily on your radon level, your home, and your personal circumstances.
Lowering radon reduces your long‑term cumulative exposure and your lifetime risk of lung cancer. Many homeowners choose to mitigate for peace of mind, long‑term health protection, and improved home value.
