According to the radioactive ray detector and the sensitivity calibration method of the radioactive ray detector in the normal and redundant working states, the plateau characteristic curve of each sub-detector is measured, and the benefit reduction state of the sub-detectors caused by partial pressure in a combined detector can be accurately obtained. By disconnecting the voltage of one sub-detector in the detector, the detector is in different detector states, a multivariate linear equation about the mutual shielding effect parameters of the sub-detectors can be obtained, and the benefit reduction caused by the mutual shielding effect to the sub-detectors can be accurately obtained by combining the obtained benefit reduction state parameters caused by the partial pressure of the detector. According to the method, the reduction and the benefit caused by the partial pressure of the detector and the reduction and the benefit caused by the mutual shielding effect of the sub-detectors are decoupled, the influenc
