<P>PROBLEM TO BE SOLVED: To improve a contaminant selecting method for continuous flow and an adaptive device. <P>SOLUTION: The contaminant selecting method for continuous flow includes the steps of: carrying a contaminant from a supply point to a selection point by a first conveyor; measuring the radioactivity of the contaminant by a first sensor arranged between the supply point and selection point, and having its sending side facing an upper side of the conveyor; selecting the contaminant by a selection device at the selection point; measuring the radioactivity of the contaminant by a second sensor; calculating a difference measurement by subtracting a measurement of the second sensor from a measurement of the first sensor, the second sensor having its sensing side facing an upper side of the first conveyor and arranged upstream from the first sensor, or having its sensing side facing to a lower side of the first conveyor; and making the selection step subordinate to a result of comparison between some threshold and the measurement of the first sensor or the difference measurement. <P>COPYRIGHT: (C)2013,JPO&INPIT |
