| A simple form of apparatus called the spinthariscope has been devised to show these scintillations. |
| Unlike other carbon-dating methods that monitor scintillations produced by radioactive decay, the TAMS method counts the actual number of carbon isotope atoms in a sample. |
| I loved to hold its face close to mine in the dark and watch the scintillations produced every time a radium nucleus decayed. |
| When alpha particles bombard a crystal phosphor, tiny scintillations are visible to microscopic observation. |
| The young physicists beamed alpha particles through gold foil and detected them as flashes of light or scintillations on a screen. |
| Bill handed out two spinthariscopes, which we passed around in the dark room to see the scintillations for ourselves. |
