Where Does Radon Come From?
• The natural radioactive decay of Uranium and other heavy elements (such as Vanadium) in the soil
• Radon is found everywhere in the United States• You get exposed to radon daily, but in
concentrations that are well below dangerous (but not risk free) levels – except at home, work, or in any building

How does radon get in?
• Through cracks in the foundation• Around plumbing and electrical lines• Through water when wells contain high levels
of radon gas

What level of radon is safe?
• Radon is measured in picoCurries per liter of air (pCi/L)
• The level or radon in outside air is 0.4 pCi/L on average
• The average indoor level is 1.3 pCiL• Mitigation should occur when levels exceed 2
pCi/L and MUST occur when over 4 pCi/L• THERE IS NO “SAFE” LEVEL in the home or
workplace.

How do I measure radon levels?
• There are a two test types, short term and long term
• Short term tests are less definitive and run from a few days to a few months.
• Long term tests are more definitive and take 6 months or more
• Since any level of radon be dangerous, either test is effective.

What should I know about radon?
• Mitigation should occur when levels exceed 2 pCi/L
• THERE IS NO “SAFE” LEVEL in the home or workplace.
• Smoking plus radon levels over 2 pCi/L magnify your risk of cancer several fold (4 times greater than dying from poison)
