Seeing visible light flashes in the scintillator was one of oldest ways how we observed ionizing radiation. It's more then 100 years old method. "This built upon the work of earlier researchers such as Antoine Henri Becquerel, who discovered radioactivity whilst working on the phosphorescence of uranium salts in 1896. Previously, scintillation events had to be laboriously detected by eye, using a spinthariscope (a simple microscope) to observe light flashes in the scintillator." | ||
