2. Presentation Outline Challenges Facing Environmental
Risk Research
II. Risk Assessment of Radon
A. Ionizing Radiation Dosimetry
B. Lung Cancer Risks
C. Stomach Cancer Risks
III. Conclusions
3. Challenges Facing Environmental Risk Research Majority of environmental causes of disease that we research today are associated with small to moderate risks (~10 to 50 percent increase in chances of getting cancer)
- Indoor air radon risk ~ 30% increase
Environmental exposures typically are small and/or low dose
4. Challenges (cont.) Environmental exposures will typically be to a mixture of plausible hazards
(smoking)
Involuntary and ubiquitous nature of environmental exposures makes it difficult to quantify the exposure
(determine exact “dose”)
Ethics prevent doing “clinical trial” type studies
