回転検出機構。 The drum is rotated around its axis using a rotary table, and a radiation detector placed opposite to the side of the drum is moved in the direction of the drum's axis to scan the entire surface of the drum to determine the intensity and distribution of radioactivity in the radioactive waste contained in the drum. In a drum monitor that measures the temperature of the drum, a plurality of gap analog sensors are positioned on a vertical plane close to the side surface of the drum and in a vertical straight line over a length that is a large proportion of the total axial length of the drum. One revolution detection mechanism for a drum monitor, characterized in that it is equipped with a detection unit that outputs a detection signal for one revolution of the drum by simultaneously detecting the step at the joint of the drum with each of these gap analog sensors. .
