What You Need to Know About Radon

Radon cannot be seen, smelled, or tasted

Adverse health effects of radon – lung cancer - are not immediately experienced

You can be exposed to radon for years without ever detecting its presence in your home

Elevated levels of radon can be found in both new and old buildings

Can be found in all types of buildings – not just homes

Radon levels vary from house to house – only way to know for sure is by testing the house

The risk of developing lung cancer at 4.0 pCi/L is estimated at about 7 lung cancer deaths per 1000 persons - no single person’s risk of developing lung cancer can be estimated

Enters through the foundation - basement, crawlspace, or slab

Typically radon levels are highest in lowest areas of the home

Tests should be placed in lowest livable area - At least 20 inches from floor and at least 3 feet from openings in exterior walls

Short test usually takes 2-3 days - Data collected for less than 48 hours should be considered invalid

• Long term testing (at least 91 days) - Preferred method as radon levels can vary from season to season or if short term test reads above 4.0 pCi/L
