レベル計校正装置。[Claims for Utility Model Registration] 1. A wide range detector, a radiation source container that irradiates the entire detector with gamma rays, a converter that converts the output from the detector into a necessary signal, and a converter. A continuous gamma ray level meter consists of a linearization circuit that linearizes the output, and a calibration plate that produces gamma ray absorption equivalent to that of the object to be measured, which is installed in front of the irradiation port of the radiation source container, and this calibration plate is connected to the measurement object. 1. A gamma ray level meter calibration device comprising a mounting mechanism that moves so as to correspond to changes in the level of an object. 2. A gamma ray level meter calibration device as set forth in claim 1 of the utility model registration claim, characterized in that it is provided in front of a wide range detector.
