What is radon, and why do we care about it?

Radon is a naturally occurring radioactive gas that is produced by the radioactive decay of radium. Breathing high concentrations of radon can cause lung cancer.

Is it dangerous, and what can be done about it?

For  these answers, and more, visit the "Frequently Asked Questions (FAQ)" page.
Should I test my house for radon? The Environmental Protection Agency says yes, everyone should test.  But we, along with colleagues at Columbia University, have developed a web site that will help you decide whether to test, based on information about your home and your personal risk preferences.  We suggest that you visit that site to get specific advice for your home.

 What did the LBNL high-radon project do?

Predictions and maps   Predicted distributions of long-term, living-area radon concentrations for nearly all counties in the U.S. 
Geology Quantified the extent to which different types of geologic information can be used to predict indoor radon concentrations.
Measurements Found ways of calibrating different types of measurements without making multiple measurements in the same home (e.g. predicting long-term living-area concentrations based on short-term basement measurements).
Statistics Found ways of minimizing problems due to small sample sizes, when trying to estimate geologic effects or county average concentrations from small numbers of measured homes. Worked out implications for who should test for radon (You can visit a web site that we made along with colleagues at Columbia University).
