Blue Plumbogummite Specimen with Yellow Pyromorphite on Matrix Mildly Radioactive
Shipped with USPS First Class
Alpha Particle Emitter
This specimen contains unknown natural radioisotopes. In the last pictures, a quick measurement with the Radiacode 101 shows peaks in the thorium decay chain. In the second picture, the measurement was taken with a pancake probe via the GQ GMC-600+.
If your Geiger counter does not detect alpha particles, you may be disappointed with this specimen. It is not detectible with the GQ GMC-300E Plus, which uses a beta gamma sensitive GM tube.
