“Geek Speak”
“Geek Speak”
Health Effects
• Lung cancer• Leading cause of lung
cancer in non-smokers
• 21,000 lung cancer deaths per year
EPA/WHO
• EPA: 4.0 picocuries per liter of air – action level• Below 4.0 pCi/L, suggest action
• WHO: 2.7 pCi/L• NOT U.S. guideline• Will eventually be EPA guideline
EPA/WHO
pCi/L Never Smoked Smokers

Number of people in 1,000 that will develop cancer from radon
Measurement
•Long-term • 6 to 12 months• Alpha-track• Most accurate
•Short-term• Typically 2 days• Passive (carbon or electric samples)• Continuous
Test Preparations
•Close windows and doors 12 hours prior
•Maintain closed conditions
•Operate mechanical equipment as normal
•Do not touch monitors!!!
Items that affect results
• Winter• Elevated
• Stack effect• Snow cover
• “Normal”
• Storms• Elevated
• Wind• Barometric
pressure• Rain cover
• Not “Normal”
• Furnace• Elevated
• Non-High Efficiency Furnace
• Ductwork• “Normal”
• Air Exchangers• Lowered• “Normal”
Mitigation systems
