Abstract

The invention provides a radioactive water filter waste filter core measuring system and method. The method comprises the following steps that a machinery stand drives a waste filter core to be testedto do three-dimensional movement; a gamma spectrometer and gamma rays released by radionuclides in the waste filter core to be tested act on each other; the distribution of each radionuclide in the waste filter core to be tested, the total activity and the activity ratio are obtained through the total energy peak count rate analysis of each section of the waste filter core to be tested obtained through measurement; and a control unit selects a measuring point, plans a measuring path, automatically controls the movement of a rotating table and visually displays the measuring result. The systemand the method have the advantages that the sectioned multi-point detection on the waste filter core is realized; and a more precise and detailed gamma spectrum type of the waste filter core can be obtained. The guarantee is provided for nuclear power plants to more accurately evaluate the types and the activity of the radionuclides in waste filter core waste barrels by a dose rate reckoning method so that the radiation safety of measuring personnel is ensured and the relevant requirements on national radioactive waste treatment and disposal can be met.
