G21148 - UV LED, Battery Radioactive Vaseline Powder/Chunks

The Electronic Goldmine Verified independent store

→

Small glass vial 1.10" tall X 0.58" diameter is about half full of small radioactive Vaseline glass chunks and ground up Vaseline glass powder. The combo package includes a UV LED and a CR2032 coin battery. When you place the leads across the coin battery (long lead on +), the vial will light up a bright green from the fluorescence property of the Vaseline glass. If you pour out the glass powder/chunks in a pile and bring a sensitive Geiger counter near it (such as our C8600 with a SBM20 tube) the counter will increase its clicking, indicating the slight radioactivity of the Vaseline glass particles.
