Abstract: A method for acquiring a nuclide activity with high nuclide identification ability applicable to a spectroscopy measured from sodium iodide detector is described. In performing this, an electronic impulse signal received by the sodium iodide detector is transformed into a spectroscopy. Then, the resulting spectroscopy is analyzed in characteristics with some previous calculations. The analysis result provides an assistance in establishing a system capable of identifying a nuclide and calculating the activity of the nuclide, which not only features an excellent nuclide identification ability but also presents a fantabulous reconstruction result. Thereby the present invention may be used for establishing a system capable of qualitative nuclide identification and activity determination that can be adapted in applications of waste clearance management.
