The invention relates to the technical field of scintillation detector detection control, and discloses an automatic detection control circuit and method suitable for a scintillation detector. The automatic detection control circuit comprises a light controller module used for periodically outputting light pulse signals; the detection control module is used for detecting the amplitude of an electric pulse signal output by a main channel of the scintillation detector in real time, outputting the electric pulse signal from the main channel if the amplitude of the electric pulse signal is greater than a preset voltage amplitude, and outputting the electric pulse signal from the main channel if the amplitude of the electric pulse signal is less than or equal to the preset voltage amplitude; and if so, outputting an electric pulse signal from the standby channel of the scintillation detector. The problem that an existing circuit for achieving automatic switching output of the scintillation detector channel is comp
