About What It Measures
Should You Test Your Home for Radon?
Why radon is a leading cause of lung cancer after smoking, the EPA's 4 pCi/L action level and the WHO's 100 Bq/m³ reference level, how to test, and why long-term averages matter more than one reading.
What's the Right Humidity at Home?
Why the US EPA suggests keeping indoor humidity between 30 and 50 percent and under 60, what too damp and too dry air do, how temperature changes the reading, and how to follow your home's humidity.
