To go along with my posts Radium Sources and Uranium Glass, here are my miscellaneous samples that don’t fit easily into either category (despite some having the same active elements). These are Fiestaware, uranium ore samples, thorium sources, and a few other things I have laying around. All these and more can also be found on my Instagram page. Enjoy! Continue Reading
To go along with my Uranium Glass and Other Sources posts, here are the pics of my radium sources; clocks, watches and compasses. In the first couple decades of the 1900’s, radium was painted onto things like clocks because it glows in the dark; hit it with a blacklight, and not only will it glow, but the glow fades away slowly too. Of course, that depends on how depleted the radium is. Again, like with the glass, these are very safe to own and keep, just wash your hands after handling and don’t touch any of the faces directly if you happen to have one missing a cover or something.

I’ve done CPM (counts-per-minute) readings on pretty much all of my radiation sources with the Radalert 50. Below are all my uranium-glass sources. Some are Vaseline glass, some are custard glass, some I’m not sure about, but they all were colored with uranium (or thorium) and so they read on the Geiger counters. They are perfectly safe to have and even to use; the radiation levels they emit are negligible. Continue Reading
Did a few Gamma Specs today, here are the results.
The first one was an orange Fiestaware cup. I believe they colored it with Uranium-Oxide, which is what makes it radioactive. The results here show us that Thorium-234 and Uranium-235 are both certainly present.
Gamma Spectroscopy is the identification of radioactive isotopes based on the gamma radiation energies emitted by a source. As a home gamma spectrometry hobbyist, I use radioactive sources such as vaseline glass (colored using Uranium), orange Fiestaware (colored with Uranium oxide), Radium-painted watches and clocks, Thorium lantern mantles, and even Uranium ore samples. Most of these are examples of common household items that emit radiation, and I find many of these items at antique stores (most of these things made today do not contain radioactive elements).

Less than a year ago I downloaded a joke Geiger Counter app that would sound like something hot was nearby if you turn your phone a certain way. I played with it at the grocery store to try to mess with people but I don’t think anyone even noticed. Continue Reading
