17 th National Radon Conference 2007 International Radon

17 th National Radon Conference 2007 International Radon Symposium Sept 9 -12, 2007 ~ Draft Estimate ~ State Radon-related Lung Cancer Deaths • These are unofficial preliminary draft estimates, and modest changes are likely as EPA refines the data and methodology. These estimates will be updated periodically. • These estimates were derived using a methodology similar to that used in EPA’s 2003 risk assessment (www. epa. gov/radon/risk_assessment. html). • The data, methodology and other factors used in calculating the state estimates will be included in a short paper being prepared now. • These estimates are intended to put the state specific risks in context to the national risk estimate (i. e. , the 21, 100 annual radon-related lung cancer deaths). States should also consider how to use these estimates strategically in their SIRG program and related risk reducing activities. • Remember, the SIRG program has three general criteria for making State grant award decisions: (1) degree of risk; (2) funding/match; and (3) measurable results/performance. 1 -5 Draft Sep-07 Jalbert/Pawel/Carter/IED
