Method for Analyzing Radionuclide and Apparatus for Analyzing Radionuclide

摘要

The present invention (A) preparing a sample containing Fe-55 and Ni-59; (B) Converting X-rays generated from Fe-55 and Ni-59 contained in the sample into electric charges, and measuring the intensity of photon energy using silicon as a medium when the electric charges move in a drift electric field Obtaining an X-ray-derived energy spectrum of the Fe-55 and Ni-59 by detecting with at least one X-ray detector; And (C) determining the radioactivity of Fe-55 and Ni-59 contained in the sample from the X-ray-derived energy spectrum of the obtained Fe-55 and Ni-59; a method for analyzing a radionuclide comprising And a first storage container for storing samples containing Fe-55 and Ni-59. It is disposed at a certain distance from the first storage container, converts X-rays generated from Fe-55 and Ni-59 contained in the sample into electric charges, and uses silicon as a medium when the electric charges move in a drift electric field. At least one X-ray detector for measuring the intensity of photon energy to obtain an X-ray-derived energy spectrum of the Fe-55 and Ni-59; And a measuring unit for determining the radioactivity of Fe-55 and Ni-59 contained in the sample from the energy spectrum derived from X-rays of the obtained Fe-55 and Ni-59; and a radionuclide analysis apparatus comprising will be.
