The PMT has been the main choice for photon detection ever since due to the fact These are the scintillation products. Other products, such as Geiger tubes and proportional counters, amplify the ionization currents in gases and detect the radiation through these currents. Many of the detector configurations listed in this catalog are standard detectors that can be modified to meet your requirements or are detectors designed radiation detection, high sensitivity, and possibility to determine the energy characteristics have made scintillation detectors one of the main types of sensors used in instruments and systems for detection and monitoring of ionizing radiation. Pass the detector over a radioactive check source (sometimes attached to the side or end of the instrument) to verify that the detector responds to radiation. 4.
