7. Health Effects Lung cancer Leading cause of lung cancer in non- smokers 21,000 lung cancer deaths per year

8. 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

10. Measurement Long-term 6 to 12 months Alpha-track Most accurate Short-term Typically 2 days Passive (carbon or electric samples) Continuous

11. Test Preparations Close windows and doors 12 hours prior Maintain closed conditions Operate mechanical equipment as normal Do not touch monitors!!!

12. 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”
