1. a radiation (20) detector cells (100,300), it comprises:

  • Transducer (10), it converts described radiation (20) to secondary photon (22);

    First photodetector (102,302), its optical coupled are to described transducer (10), and having has first of minimized radiation flux to survey dynamic range, and operates to convert at least a portion in the described secondary photon (22) to first electronic signal;

    Second photodetector (104,304), its optical coupled are to described transducer (10), and having has second of minimized radiation flux to survey dynamic range, and operates to convert at least a portion in the described secondary photon (22) to second electronic signal;

    Wherein, the minimized radiation flux of described first dynamic range is less than the minimized radiation flux of described second dynamic range.
