Analyzing Radioactive Glass from the Trinity Test

The Trinity site is open twice a year to visitors. When I went 10 years ago there were still bits of the blueish-green glass mixed in with the grass and sandy soil. A small section was preserved and coverered with a low windowed box. The ground inside was entirely covered with the strange material.<p><a href="http://www.wsmr.army.mil/PAO/Trinity/Pages/HowtoGetThereDirectionstothesiteforthebiannualopenhouses.aspx" rel="nofollow">http://www.wsmr.army.mil/PAO/Trinity/Pages/HowtoGetThereDire...</a>

As an undergrad at Georgia Tech you should know that if one of my professors caught me writing some significant digit nonsense like 1.0272303 ± 1.031768 Bq/kg I would not have gotten a degree.<p>1.0272303 ± 1.031768 Bq/kg or rather 1.0 ± 1.0 Bq/kg means that your experimental error is so large that your result is compatible with both 0 and 2 Bq/Kg. What's the point of adding all those significant digits if you're telling us that your result is imprecise, or rather that your experiment can't effectively tell if there is any activity from Cs-60.<p>(edit: I wasn't an undergrad at GT)

Both of the videos at the end of the article are absolutely fascinating (as is the rest of the article, but I almost skipped the videos; I'm glad I didn't).

A Quote: "Kenneth Bainbridge, director of the Manhattan Project, was not amused with Fermi scaring all the guards."<p>Correction. Leslie R. Groves, Jr. was director of the Manhattan Project.

Wow, amazing<p>So I suppose what points this to being Trinity is the ratios, since the values are very off from the Trinity data in the tables (because of decay)
