WebThe choice of a particular detector type for an application depends upon the X-ray or gamma energy range of interest and the application’s resolution and efficiency requirements. Additional considerations include count rate performance, the suitability of the detector for timing experiments, and of course, price. DETECTOR EFFICIENCY. WebThe basic principle of operation involves the radiation reacting with a scintillator, which produces a series of flashes of varying intensity. The intensity of the flashes is proportional to the energy of the radiation, and this feature is very important.

WebThe ray or particle will be absorbed within the thin scintillator and the light produced by this interaction will be able to pass through the remaining thickness to allow the gamma ray to be detected. A high-energy gamma ray is likely to pass right through the thin scintillator without interacting. WebFeb 13, 2024 · It does not require any ionization event to happen so that the tube must not be used in this region. The Geiger Muller counter can account for about 500 particles per second. The GM counter will not register those particles that pass through it in the dead time. Dead time refers to the time taken by the tube to recover between counts. granola bar recipe without honey
