Limits of detection for P32 Phosphor Screens
Known amounts of radioactivity, across 8 logs of specific activity, were counted in a scintillation counter. The same amount of radioactivity was spotted on a nylon membrane and exposed to a phosphorimager screen for various exposure times. Upper and lower limits of scintillation counter, and different exposure times is shown.
