PURPOSE: To remove elements activated by irradiation which have respectively different magnetic characteristics and which comprise elements of high activity and low activity effectively. CONSTITUTION: Activated elements 4 which have respectively different magnetic characteristics and comprise constitution components of high activity and low activity are ground into ground groups of the both constitution components. Fragments of the first constitution component are separated by a magnetic means 12 and fed to first discharge and storing parts 18, 19, 20. Fragments of the second constitution component are separated by the magnetic means and fed to a continuous carrying means 21. The detection of the fragments of the first constitution component are performed in the continuous carrying means 21 and, when this component is not detected, the fragments in the carrying means 21 are fed to second discharge and package parts, 24, 25, 26. |
