    The damage caused by the alpha particle in Colorado was not from a Uranium mine, but rather a fire at a fuse plant, for atomic bombs, resulting in massive contamination in the Denver area, in the early post-war period. The incident has been air brushed from history, but a little scratching around your search engine will soon start turning up snippets.

    Ah, here's an interesting story. So one day back in like the 2000s, there was a comet shower or something. Now my family decided to go and watch it along with me of course and we went to our observation area. So while we were watching these star shower a bright light flashed in my eyes, and I was like 10 years old or something at the time maybe even less, so this bright light flashes and I scurry inside the house. They ask "Hey, why did you go back inside the house?" but I was so scared and confused on why nobody reacted the same way. Now years later, I think I finally have the answer.
