Are you a Rocky Flats Downwinder?

The Rocky Flats Plant operated from 1952 until 1989 as part of the United States’ nationwide nuclear weapons complex. The Rocky Flats facility manufactured plutonium trigger mechanisms for nuclear weapons from various radioactive and hazardous materials. Manufacturing activities, accidental industrial fires and spills, support activities, and waste management practices contaminated soil, sediment, groundwater and surface water with hazardous chemicals and radioactive constituents.

Fact Sheet 2017

In 2015 Metropolitan State University released Preliminary Results of its Health Survey of Rocky Flats Downwinders. Data pertaining to illness was geoplotted on a map of the survey area. Two sourced maps of contamination from the plant in the form of radiation and fires were overlaid on the geoplotted data to identify possible correlation between illness and radiation exposure in the area.iii The results are anecdotal, compelling, non-conclusive.
