Scintillation Counter

In this counter, light flashes produced in a scintillator (ZnS [Ag]) by ionizing radiation are converted into electrical pulses by a photo-multiplier tube. The scintillation counter is especially suited for the analysis of alpha-emitting

gaseous radioisotopes such as radon. Radium 226 analysis by radon de-emanation into a Lucas cell is a classic use of the scintillation counter (Greenberg, Clesceri & Eaton 1992) (Figure 11.24.2). Calibration of each cell is required to obtain quantitative results.
