The single sample that halted the construction of the Jefferson parkway was erroneous. Feel free to Google and you will see that there was limited media coverage of this sample turning out to be bunk. Naturally the media coverage was very heavy when the sample was initially taken.

Again, I have huge animosity towards antinuclear activist because they have completely sealed our grave when it comes to climate change. We could all be like France now if not for them.

It should be noted that the super fund site was cleared by scientists from the EPA, scientists from the state of Colorado, and scientist from Jefferson County separate from their public health division. Decades of testing have been done. Colorado State University has also done extensive independent testing.

The mainstream scientific organizations have concluded that it is a safe area. The same people who attack vaccine hesitant people for not following scientific authorities and instead embracing fringe scientists have embraced fringe scientists and opposed scientific organizations on this exact topic. It is truly hypocrisy.

This article details a Colorado State University and Colorado state government review of the soil samples that the Broomfield City council used as an excuse to embrace the whims of anti-nuclear activists. (You can say this isn't rooted in anti-nuclear activism all you want. I live here and I know exactly who the protesters are and what their thoughts are on nuclear power. I have yet to meet a single person protesting Rocky flats who also happens to believe nuclear power is okay. There aren't any.)

"In a 28-page report, the Colorado Department of Public Health and Environment determined that "remaining Rocky Flats plutonium in the Jefferson Parkway transportation corridor and offsite poses a small risk, well within regulatory limits for radiation."

The report included an independent review by Colorado State University researchers."

"The health risk associated with remaining radionuclides is very small," the report reads. "The Colorado Department of Public Health and Environment's Colorado Central Cancer Registry studies have not detected an overall pattern of cancers tied to Rocky Flats. However, interest in Rocky Flats remains strong."

The soil sample study, which was conducted by the Jefferson Parkway Public Highway Authority, began in May 2019. In August, the highway authority notified state public health officials of inconsistent testing results in one sample, which showed elevated plutonium levels. A second test from the same sample showed a much lower level, the authority said."

Note that that the above sentence is something showing that you fell into media misinformation based on an initial take without follow up.

When you live in Colorado at a high altitude, there are two sources of radiation that are all around us. The sun, where we get far higher UV exposure than others at lower elevations, and the naturally occurring uranium/radon in the rocky soil. I own a Geiger counter from a trip I took to Chernobyl many years ago. (My last company had an office in Kiev and I had to go there quite a bit). I really appreciate the lecture on the wildlife surrounding Chernobyl. I bet you haven't been there but I have.

There's a constant background radiation in Colorado. But guess what:
Like the rest of the state the incidence of cancer is far lower than in the rest of the country. My family in Southeastern Virginia lives in an area with vastly higher rates of cancer than where I do.
