Important Points for Research about Rocky Flats

Here are several important points for research:

  • April 2020, a new analysis of soil from near the former Rocky Flats nuclear weapons plant has documented widespread contamination by “hot particles” of plutonium. The research by Michael E. Ketterer and Scott C. Szechenyi from Northern Arizona University (NAU) concluded, “These particles are found to be pervasive in non-US Government land east of Rocky Flats, and it is reasonable to believe that ongoing wind transport is continuing to spread the contamination across open space used by the public, and toward residential areas.”

  • April 2020 update about Dr. Ketterer's research

  • September 2019 update about Dr. Ketterer's research

  • August 2019, a soil sample on the East side of Rocky Flats included an exceedingly high measurement of plutonium at 264 pCi/G. Consider this as opposed to background radiation of plutonium at .04 pCi/G.

  • The CDPHE Hazardous Materials and Waste Management Division receives federal grant money from the Department of Energy. Thus they operate under a conflict of interest with the federal agency responsible for nuclear bomb production.

  • Link to federal grant documentation

  • 7 local school districts made a commitment to not allow field trips to Rocky Flats. This includes BVSD, SVVSD, Adams 12, Adams 14, Jeffco Public Schools, and Denver Public Schools.

  • Link to The Nation Report Article

  • In 2016 property owners in the Cook V. Rockwell case received a settlement of $375 million due to contamination from the Rocky Flats Plant. The jury found that “plutonium will continue to be present on the class properties indefinitely”.

  • 6/18/2019 Broomfield City Council Study Session (video of the Jefferson Parkway agenda item begins at 2:43)

    • Presentations were heard from CDPHE, Engineering Analytics, and representatives from citizen groups.Here is a list of the citizen group speakers and their credentials:

  • Jon Lipsky, former FBI agent who led the 1989 raid on the Rocky Flats Nuclear Weapons Plant, presenting on environmental contamination by the Plant.

  • (Randy Stafford covered this presentation because Dr. Moore was unable to attend) Dr. LeRoy Moore, first-hand participant in setting plutonium soil standards for the Rocky Flats cleanup project, presenting on that soil standard setting process.

  • Dr. Harvey Nichols, CU professor emeritus of biology who studied Rocky Flats airborne contamination, presenting evidence that the entire Refuge was dusted with tiny plutonium particles; health implications.

  • Randy Stafford, presenting on his survey of all past offsite soil and public health impact studies listed in his JPAC position paper (linked from

  • Tiffany Hanson, founder of , presenting on reports her organization has received about sick and deceased downwinders, including the MSU health survey.

  • Dr. Gale Biggs, micro-meteorologist (retired) who chaired the Air Committee of Governor Romer’s Rocky Flats Scientific Monitoring Panel, presenting on air monitoring for plutonium.

  • Dr. Michael Ketterer, Northern Arizona University professor emeritus of chemistry and specialist in radionuclide soil studies, presenting on soil contamination in the Parkway right of way

  • Ms. Pat Mellen, Esq., subject matter expert on Rocky Flats cleanup history, presenting on the importance of the Special Grand Jury 89-2 records and why they should be reviewed.
