Connected the Mirion HDS-101 to the new laptop wirelessly via Bluetooth. To make it work you have to go into Bluetooth settings and see which Com port is being used, then in the software go to Bluetooth configuration and set it to that port (I’ll do a video in the near future). The last pic is just a background run I did, the other graph is the Cs137 source attached to my Ludlum model 2.
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).
