Cancer Risk
The EPA chart below outlines the possible lung cancer risk per 1000 people at 4 different radon levels.
Risk per 1000 people
pCi/L = picoCuries per liter
| RN222 level | Non Smoker | Smoker |
|---|---|---|
| 10 pCi/L | 18 people | 150 people |
| 8 | 15 | 120 |
| 4 | 7 | 62 |
| 2 | 4 | 32 |
Radon Levels
Here are some radon levels to know about:
- Average Radon level in Air = 0.4 pCi/L
- Average Radon in US homes: 1.3 pCi/L
- EPA Action Level: at 4.0 pCi/L or above the EPA recommends mitigation.
- WHO (World Health Organization) Action Level: 2.7 pCi/L
- Mitigation brings homes below: 2.0 pCi/L
