Radiation detector and X-ray analysis apparatus and radiation detection method using the same

摘要

There is provided a radiation detector capable of detecting radiation without occurrence of dead time while maintaining an exposure state by continuously penetrating radiation, and an X-ray analysis device and a radiation detection method using the radiation detector. A radiation detector 100 that detects radiation synchronously with an external device 200 includes: a sensor 110 that generates pulses when radiation particles are detected; a plurality of counters 140a, 140b provided so as to be capable of counting the pulses; and a control circuit 160 configured to switch a counter for counting the pulses from the plurality of counters 140a, 140b when receiving a synchronization signal from the external device 200.
