Here are three short videos I made on the main functions of the CDV-718 survey meter. This is the same as the military Radiac Set AN/VDR-2, except that it’s Civil Defense (FEMA) Yellow instead of Olive Drab green, and it reads in Roentgen (R) and mR, instead of Grey (Gy) and mGy. Continue Reading
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
The results are in!
I picked up a “Double Cooler” today, a drink cooler with internal and external compartments for the purpose of having two separate drinks in one cooler. 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.
