A vintage 1962 Czechoslovak cold war military Geiger counter RBGT-62 in operation. After 55 years this amazing machine still works well. I am showing how to put it into operation and measuring some radioactive items like FiestaWare, thorium lantern mantle and radium watches.
WARNING:
Never try to do those experiments. Radioactive items may be quite dangerous. You do everything at your own risk!
