Case Study continued:
Church Rock Radon

• Is health of Church Rock residents at risk?
  • If still present, high outdoor Rn levels —
    • approach USEPA indoor-air "action level" of 4.0 pCi/l
    • range from 10-15 times > USNRC public dose limit
  • Time-activity patterns —
    • residents tied to land, captive to exposures
  • Combinations of exposures —
    • food, water consumption: animals studies confirmed bioaccumulation of contaminants in food chain
    • occupational: many former miners live in area
  • Socioeconomic status —
    • lower incomes, existing health conditions —> susceptibility
