Webscintillation counter, radiation detector that is triggered by a flash of light (or scintillation) produced when ionizing radiation traverses certain solid or liquid substances (phosphors), among which are thallium-activated sodium iodide, zinc sulfide, and organic compounds such as anthracene incorporated into solid plastics or liquid solvents. The light flashes … The first electronic scintillation counter was invented in 1944 by Sir Samuel Curran whilst he was working on the Manhattan Project at the University of California at Berkeley. There was a requirement to measure the radiation from small quantities of uranium and his innovation was to use one of the newly-available highly sensitive photomultiplier tubes made by the Radio Corporation of America to accurately count the flashes of light from a scintillator subjected to radi…
