PURPOSE:To execute a work matching the timing of a measuring operation and a classifying operation in a radiant ray measuring part, by placing plural trucks which can move independently, and controlling the running and stopping of the truck in a truck control part. CONSTITUTION:A stop position of each truck is a saving area 11, for an object to be measured, the first holding place 12, a radiant ray measuring part 1, a radioactivity contaminated object saving area 14, a same non-contaminated object saving area 15, the second holding place 17 and the third holding place 18, and a truck control part 4 inputs output signals [truck exists], [no truck exists] {provided that [under measurement], [under non-measurement], [contamination exists], [no contamination exists] from the radiant ray measuring part 1} from detectors 21-27 provided on each position, outputs signals of [run] and [stop] to transmitters 31-37 provided on each position and moves a truck. According to such a constitution, each truck goes round on a rail successively, and when an object to be measured is loaded and unloaded to and from the truck in the saving area 11 for the object to be measured, the radioactivity contaminated object saving area 14 and the non-contaminated object saving area 15, measurement of existence of radioactivity contamination of the object to be measured, and classified custody according to existence of contamination are executed automatically, continuously and smoothly. |
