RadioactivityCounterApp (iPhone): Private Mineral Collection, Part 1 – Pure Pitchblend, Bismuth

	RadioactivityCounterApp (iPhone): Private Mineral Collection, Part 1 - Pure Pitchblend, Bismuth Part 1 of my comparison of various radioactive mineral specimen. Beginning with pure Pitchblend, which was found in the old "SDAG Wismut, Schacht 309" - this little one is really hot. I use an asiatic Geiger-Müller Counter and the RadioactivityCounterApp of HotRay. The second mineral shown is non-radioactive Bismuth, from the same location.	From: Condordancer Views: 0 0 ratings
