• The scintillation counter that appears in Blau and Dreyfus's paper in 1945. (A) is a phototube enclosed in a metal box together with the optical bench (F) where stands the light-standard (E) and the alpha source (D), both mounted on movable carriages (G,I). The scintillation zinc sulfide screen (B) stands in front of the source and (C) is a removable shutter. The light-standard used to test the response of the tube to the light-emitting source.
